機房建置,採用電源循環測試查找硬件故障

機房建置,企業採取各種措施不讓意外停機時間中斷其數據中心業務。而進行電源循環測試,以主動監控系統並以有條不紊,有序的方式識別硬件故障是一種很好的措施。

由於在數據中心日常操作期間可能不會使用它系統的所有部分,因此這組件可能會失效或軟件模塊可能崩潰,但系統可能會正常運行數月甚至數年。在系統重新啓動(通常意外)之前,故障可能無法顯示,從而導致意外的工作負載中斷和停機時間。而企業需要通過週期性電源循環測試,以識別可能出現的問題並主動解決問題。
如果沒有看到任何問題,爲什麼要執行電源循環測試嗎?
數據中心所採用的系統管理工具包括MicrosoftSystemCenter,SolarWinds,Nagios和Zabbix這些強大的多功能平臺。幾乎所有的系統管理工具都可以提供故障,配置,會計,性能和安全管理等功能,使其成爲現代企業不可或缺的一部分。
但是,某些故障可能發生在硬件級別,但可能不會立即影響系統或工作負載,例如,可能在服務器的雙列直插存儲器模塊(DIMM)中檢測到存儲器故障。但是,如果沒有工作負載使用該內存空間,或者故障DIMM採用了故障糾正技術保護,則服務器可以繼續工作,很少向系統管理報告其直接錯誤。在大多數情況下,現代服務器的智能平臺管理界面或基板管理系統可以報告這些錯誤,但是該信息通常只是記錄,系統及其工作負載將繼續運行。
而那些未檢測到的和未解決的硬件問題纔是最大的問題。如果意外的系統崩潰或電源中斷導致計劃外的系統重新啓動,則系統的內部固件可能會看到這些問題並拒絕完成引導過程,例如,如果服務器的南橋芯片出現故障,並且USB或板載磁盤控制器功能未初始化或響應,則引導過程將停止,即使企業可能不使用服務器的USB端口,而是通過網絡訪問存儲。現在,那部門必須嘗試從意外中斷中恢復,並同時解決有缺陷的系統。
爲了避免出這種情況,請進行定期現,並主動進行電源循環測試,以強制在低級別硬件中重新啓動系統。除了在計劃外中斷或停機期間進行加擾,還可以使用計劃的重新啓動來確保數據保護,並以有組織的方式將虛擬機或存儲實例遷移到目標設備之外。接下來,循環上電,並允許硬件系統完全啓動,以顯示潛在的未知或未解決的問題。系統電源循環通常作爲組織現有關閉文檔的一部分。如果在重新啓動過程中出現問題,企業將採取更好的準備採取糾正措施。
應該如何接近電源循環測試,以及應該多久進行一次嗎?
具有高質量設計的服務器可以運行多年。當企業在彈性配置(例如服務器集羣)中部署這些服務器設計時,這些系統上支持的工作負載幾乎是不可破壞的。事實上,強調系統彈性和正常運行時間常常導致許多組織放棄週期性的功率循環。
但是如果一個服務器或存儲子系統運行了幾年,你怎麼知道它會正常啓動?如果不知道,那麼希望系統能夠成功冷啓動的唯一方法是定期進行測試。
電源循環測試需要什麼樣的依賴關係?
企業的數據中心根據需要進行電源循環測試,以便爲其業務需求達到合理的置信水平。通常,可以每幾個月或每年進行幾次電源循環。將電源循環測試與常規災難恢復和關閉測試保持同步,以便同時處理這兩個目標可能是一個好主意。
有時,也有一些外部因素影響數據中心的正常運行,例如變電站升級改造或重要的建築物改造,迫使企業使數據中心離線一段時間。如今,計劃停機可以減少業務中斷,因爲企業的數據中心可以輕鬆地將工作負載遷移到輔助數據中心或雲計算,所以任何這團隊準備處理計劃內的設施關閉也應該能夠進行常規電源循環。
服務器硬件有任何風險嗎?
當數據中心啓動和運行服務器或存儲陣列時,總是有一定程度的電、熱和機械應力。當允許電子元件冷卻並再次升溫時,可能會導致熱應力,可能會導致邊緣連接失效,並導致過早的系統故障。類似地,如果讓老化的磁盤或冷卻風扇冷卻,它可能因潤滑劑耗盡而卡住,並導致磁盤/風扇主軸或產生其他微妙機制的問題。
另外,還存在潛在的邏輯風險。意外的配置更改可能會使它系統超出範圍,並導致由於系統配置管理工具的警告或應用程序啓動問題,例如,如果系統重新啓動並嘗試安裝意外或未批准的修補程序,則配置管理工具可能會暫停工作負載或服務器集羣啓動,直到系統的批准配置恢復爲止。
這樣的問題是罕見的,特別是在現代的數據中心節能系統中。雖然一些它專家認爲電源循環可以減少這種故障的可能性,但是計劃的電源循環測試正是沉澱,隔離和解決這些類型問題的辦法。早期暴露任何問題最好等到意外的電源故障或應用程序崩潰,並發現系統未正常啓動的隱患。
隨着數據中心使用虛擬化和羣集,其工作負載將繼續運行,同時識別和修復故障系統。

How does the datacenter migration and how to store the infrastructure?

Datacenter migration, big data analysis and the Internet of things are helping organizations build smarter storage infrastructure.Cheaper and more intensive cpus drive smarter built-in intelligence to every layer of the data storage infrastructure stack.

In storage, for example, too much computing power can be used to deploy agile software defined storage (for example, HP EnterpriseStoreVirtual), switch to super fusion architecture (for example, HyperGrid Nutanix Pivot3, SimpliVity), or by intelligently redistribution storage function to optimize the application server and disk I/O host.
However, all of these built-in intelligence have a fault, is may reduce people in data storage infrastructure and change (any IT changes) between visibility, whether IT is due to the repair and upgrade the user, extension, or complex error and component failures.Or, in other words, with powerful and cheap processors, dynamic optimization makes it increasingly difficult to determine what is happening to its infrastructure.
So when people don't need to know any details and can simply rely on low-level components to do the right thing, until they have an absolutely autonomous data center.Now that corporate public cloud computing does not eliminate the need for in-house expertise, IT may find IT a double-edged sword.In addition, although more intelligent data storage infrastructure to help people configuration, optimization, growth plans, and troubleshooting, it may make people blind or fool, infrastructure and positive efforts to people's "will".
Although all these potential downsides require choices, people want to be in a smarter, more autonomous IT world (even if there is some risk of ai getting out of control).
It's all about data
Remember that the previous analysis was an offline process?Capture some data in a file;Open Excel, SAS, or other desktop workers and receive a suggestion a few weeks later.Today, this analysis is too long and too simple.
Dynamic optimization, with its powerful, low-cost native processors, makes it increasingly difficult to determine what is happening to our infrastructure.
Given the speed and agility of applications and users, not to mention larger data streams and flexible cloud proxies, people need insight and faster answers than ever before.The smart start from a large number of reliable data, produce more and more every day in today's infrastructure data (in fact, due to the rise of the Internet of things, people will soon be submerged in the new data), and to deal with and manage all of this information.
Storage arrays, for example, have long provided insightful data, but historically required vendor-specific, complex and expensive storage resource management applications to take full advantage of it.Fortunately, there have been a number of developments today that have enabled people to have smarter IT systems management and better and faster generation of user data:
Data processing.As the Internet of things grows, storage components are generating more and more detailed data.This growing data requires big data analysis techniques within IT itself.IT administrators spend some time learning Python and Spark skills.
Consumption API. Modern storage platform now offer or produce easy-to-use free apis (said state transfer (API), allowing anyone to (with permission) directly to use almost any type of third party access to critical data analysis tools.The standard API also enables and enhances third-party system management by integrating platforms such as OpenDataSource.
Home support calls.Most storage providers now call home support calls into their arrays, enabling them to send detailed machine logs to vendors for daily processing.Vendors can then use big data tools to aggregate data to provide proactive support and insight to customers for better product management and marketing.Family call function can also be from Glassbeam suppliers as a service, IT can also help provide a client portal as a "value added", directly to the IT end-users provide insight into use and performance.
Fortunately, today's infrastructure has a number of developments that can help people better manage smart IT systems and generate user data.
Visualization.Big data for IT provides a number of excellent visualization tools that are often used by enterprise business intelligence applications (such as Tableau).Therefore, IT itself can now build business-friendly dashboards and reports.At the same time, many vendors have made it easier to create and provide custom product dashboards and shareable widgets with a clearer and more accessible open source visual library, such as d3.js.
Next generation intelligence.Some vendors are doing really smart things outside of visualization.It is not enough for the supplier to help provide specific key performance indicators for advanced products (for example, VMwarevRealizeOperations, Tintri, Pernix/Nutanix) to transfer these detailed data to operational intelligence.As a first step, today's vendors can skillfully accumulate low-level data streams into expert "models" of health, capacity or risk.Some models generate linear predictions for unique "fractions" of each particular platform.Truly advanced modeling can take into account future workload growth and data storage infrastructure upgrade plans, and can predict non-linear performance based on analysis of queuing behavior.
Intelligent machines
With the development of big data analysis and the application of the Internet of things, there must be exciting new developments and more intelligent data storage infrastructure space.
For example, people only see the beginning of the application of machine learning in systems management.Pay attention to the machine learning more intelligent optimization, as software as a service analysis service, embedded client console for dynamic operations, strategic planning in the dashboard and portal for intelligence, and pushes it into the equipment to help them become more independent.
People should not be surprised if a car will drive itself soon.When storage arrays begin to tell people that they can process data.One day, people may have to conduct an enterprise-oriented IT intelligence test for new storage arrays to see if they are ready to run data centers.

What are the contents of website design and website maintenance?

Whether a website is successful or not, the two most important points are: website design and website maintenance.The page layout design of the website directly affects the overall visual effect and user experience of the website. The layout is disordered.Second, the maintenance of the website, slow opening of the website, or no content users want, will lead to the loss of customers.So how do you design and maintain your website?What exactly should be noted and included?

Key points of website design:
1. It is a basic principle for web designers to understand different audiences and different psychological needs at different social levels in accordance with the psychological and social psychological needs of audiences.Before the creation of website design, designers should make a series of corresponding understandings on the cultural background, aesthetic psychology and aesthetic perception of the objects they express.For different places, designers should also learn about the phenomena of regional folk culture.Only in this way can the design of web works and design objects have a close connection to achieve the hearts of readers and works, face and face exchanges.
2, web design and web maintenance to analyze user requirements, pay attention to the content layout designers in the design of the web site should be made of categories, such as enterprise website, the government website or personal web site, and so on.Because of the different types of web pages with different themes and styles, design the web cannot a presumptuous guest usurps the host's role, nor theme and site category attributes, used in text, images, colors to choose.Therefore, the first step of web design should be oriented towards users' needs and types of websites. All design work should be based on this premise and properly positioned, so as not to deviate from the theme.
3. Design theme positioning accurate web design is a kind of planning and reservation according to certain needs and purposes.Its outstanding feature is that it has considerable restraint and binding force, that is, it is restricted and constrained by the design theme.Web design works should have their own distinct themes, and the freshness of the themes determines the distinctive personality of the design.Design theme positioning requires accuracy, which is the primary problem in design principles.Deliver content web page subject is designed for information, the designer should be fully used to convey specific information, transfer the images of all the visual elements in to play the greatest visual effects, design orientation should always firmly grasp the design theme.
4. The download time of the website should not be too long. In order to ensure the website has an increasing click rate, besides attractive content, there should be a faster download speed.The speed of web page loading is very important for a website, which directly affects the user's access experience and satisfaction.If you can't open a web page for 20 or 30 seconds, the average person will be impatient.At the very least, make sure your home page is as fast as possible. If not necessary, it's best not to use large images or compress them.
5. The compatibility of websites with different operating systems and browsers generally, web pages designed by people are debugged in one operating system and browser.On the Internet, there are all kinds of operating system and browser, some of the web technology, the plug-in in different operating systems and browsers effect is different, some even could not compatible, so, we must give full consideration to the compatibility of page.A common approach is to test different operating systems and browsers to ensure maximum compatibility.
6. Regular debugging and data update. In order to attract more users, the information in website construction must be updated frequently, such as news and pictures.At the same time, often should modify the web site update, web links between sometimes appear off phenomenon, therefore, often should do the site commissioning, check whether there is a link error and repair, to maintain the normal operation of the site.
How does website maintain do?
1, ensure the normal order of the website can be access is the basis of site maintenance, of course, on the basis of the normal access as much as possible to improve the site access speed of course is better, this needs us in the chosen host and maintain a good host under the premise of normal operation for web outages in reasonable clean-up code, in order to reduce the workload analysis server page.
2, regular backup database and website source file, in order to prevent the site due to reasons such as server problem or attacked data or file is missing, as far as possible can do every day a source file and database backup, conditions are not allowed, at least also should backup once every other week.
3, web design and web site maintenance regularly for some quality content for your site users to consult, give new content to the website at any time can inspire users curiosity about our website, and it is the important factor of web site will be influenced by visitors like.
4, when the site has the rankings in search engines, there will be a lot of users through search engines for keywords to visit our website, this is to do a good job of statistics web site is very important, we need to calculated the user is through what keywords into our website, in our web site for information such as how long the time, only know these information we can learn the user's real needs, and then make the corresponding adjustment according to the user's demand, so as to make our website more perfect.
5, every day to check whether there is abnormal in our website, the server should be scanned for viruses and killing regularly, check whether the domain name is being malicious generic analytical at the same time, check whether the site is being implanted with malicious code, all in all to be very careful, you know the once you have the slightest negligence could have serious consequences.
6. It is important to timely improve the website structure, layout and other aspects that can be improved. It is important to know that the website maintenance process is a process of constantly improving the quality of the website.
7, web design and web service in web site optimization must be done to keep pace with The Times, pay more attention to the competition situation of the optimization of the site, specialty must draw lessons from others, can improve better, of course, at the same time to the shortcomings of others to take, don't be complacent.

5. The unit has a high calorific value, and the precision air conditioning used in the machine room is required for large refrigerating capacity, large air volume, small enthalpy difference and large air cooling ratio
(1) small enthalpy difference
Together, the transpiration temperature of air conditioning is relatively high to prevent the unnecessary dehumidification when cooling.
(2) large refrigerating capacity
The heat load of the data center machine room is very large, and the heat load of IT equipment is severe, so the heat load per unit area is much higher than the operating area, that is, the heat load is very large.Since these devices do not attack moisture changes, the wet load is small.This requires that the air conditioning used in the machine room can be strong enough to quickly eliminate the declared heat in unit time.
(3) high air volume
Because air conditioning in the machine room requires a small enthalpy difference of air supply, preventing unnecessary dehumidification, and other requirements of large cooling capacity, it is necessary to adopt the plan of large air volume.Large volume of circulation also is advantageous to the room temperature, humidity and so on goal of safe control, also can ensure the balance of room temperature, humidity, reach the effect of large computer room air flow distribution is reasonable, prevent engine parts heat collection.

Analysis of the elements of website design and maintenance business affairs

Website design, since the emergence of e-commerce, has been changing people's way of life, through the network into every corner, from the concept and behavior of the impact of social development. In the information age, many industrial enterprises, educational institutions and government agencies are building their own websites. The use of e-commerce can help enterprises to effectively reduce costs, maintain timely and direct contact with customers, and enhance their competitiveness. With more and more enterprises building business websites, website design and maintenance is particularly important. What are the elements of business website design and maintenance?

First, we must have good website strategy and planning to decide the online business mode and target website.
Before building a station, it should be clear that the purpose of the site is to fully meet the needs of the target users, to provide them with the urgent needs of information and resources, so that they can quickly find a solution to their difficulties in the web site, so the first step of the site planning should be to build a popular web site. The structure must be reasonably conceived. The successful business website has the following features:
1. layout design and graphics are reasonable. Generally speaking, good business website layout should follow the principle of order, balance and decoration. Layout and graphics are related to the first impression of the home page. Pictures can make the website more attractive. For example, websites that sell products online need to use pictures to provide users with visually appealing content.
2. color setting is reasonable and the web page has a sense of hierarchy. The website of the business website should try to catch the attention rather than inundate the attention of the visitors. The e-business website should be the main product display, and the use of the color of the website can not be taken out of the world.
3. clear navigation. The design website must pay attention to: the navigation is reasonable, the design should be integrated into the whole website design, it is best to add the image of the enterprise into the navigation design, so as to further deepen the understanding of the image of the enterprise.
Two, functional aspects determine the success of business website design:
In the context of business website design and maintenance, enterprise websites can be divided into three stages according to their functions and characteristics: pre-sale, online sales and after sales. Any e - business activity is suitable for this category. The pre sale stage includes companies attracting users through advertising, PR, new products and services, and other activities. Customer buying activities appear on the stage of online sales. At this stage, users can deliver orders and pay fees through network facilities. The after-sale stage includes customer service, customer problem solving and other activities.
Three, the elements of the design and maintenance of the business website:
1. The update of the content of the website
First, the maintenance of commodity information. Commodity information is the main body of e-commerce website. With the change of external conditions, the information of commodities should be constantly updated to reflect the true state of commodities.
Second, maintain the news column. The major activities of the enterprise, the latest trends in the product, the trend of the development of the enterprise, and the customer service measures are presented to the customers in a timely and real way, so as to attract more customers to visit and deal with them.
Third, website maintenance personnel should always test all web page links of the website to ensure that the links are correct.
2, the collection of user information and the timely feedback, in the daily maintenance of the website, the user's various feedback information should be processed in a timely manner, and the user can get a satisfactory reply in the shortest time. To correctly handle user's suggestions and problems, we must ensure that user reporting problems can be solved.
3, business website construction and maintenance of the site access data analysis, through the analysis of the access data, we can find the advantages and disadvantages of the website, so as to make the corresponding modification, better achieve the goal of the website construction, and help to select a more suitable means of website promotion and promotion.
4, to maintain the security of the website, the e-commerce website is open to the outside world, which facilitates the enterprise to publish business information and the customers to choose the required goods, but at the same time it also poses a threat to the security of the website. In order to maintain the good image of the website, ensure the normal operation of the business system of the website and ensure the secret of business information, the administrator of the website should constantly look for the weak links and security loopholes in the network, and repair and improve it in time.

機房建置,如何避免數據中心集成問題嗎?

機房建置,精確的電力監控對於任何數據中心運營商來說都至關重要。爲了能夠跟蹤和改進流程,確保其準確性非常重要,但是大多數數據中心所部署的電源監控系統過於複雜並且不準確。
人們對於數據中心的電源有五個關鍵要求:可用性、效率,可持續性,靈活性,定製計費。這五點是數據中心運營商具備良好的電力監控系統的基石。

然而,許多數據中心運營商發現他們正在努力正確管理和準確測量其功耗。但目前至少需要三到四個系統來測量數據中心機房各處的功率。從變壓器級一直到機架的功率測量可能會很複雜,並且通常由於衆多不同的監控系統(通常由不同的製造商提供)而導致集成問題。
數據中心運營商可以採用最新推出的模塊化電源監控系統改變這種狀況。其系統通過數據中心監控電源,這意味着數據中心技術人員只需要一個系統,而不是安裝,維護和學習三至四個不同的系統。
模塊化電源監控系統由三種不同的技術組成,可以確保其準確性,採用虛擬顯示器顯示斷路器狀態,無需附加硬件,自動更正並消除錯誤。
精確的電力監控和計量顯然是運營數據中心的重要因素。通過一些數據可以說明這一點:如果假設機架設備的功耗爲10千瓦,這意味着每年全天候運行的耗電將近90 000千瓦時。目前監控系統對數據中心的評估表明了每個機架每年運行可能具有千440瓦時的能耗誤差。對於擁萬有1個機架的大型數據中心,其功耗相當於440年萬千瓦時,每年浪費的電費約爲70多萬美元。顯然,這是一個需要重視的大問題。

Datacenter migration,how do you finish the test on time?

Datacenter migration,Starting from the first day of operation, the data centers of all sizes will face up to the "five nine" (99.999% normal run time) performance requirements. In order to meet the needs of users, the staff will improve the safety level for the electrical acceptance test of the data center. Today, effective testing is critical to the normal running time of data center, and it needs to be maintained.
Nowadays, the construction cycle of data center is becoming shorter and shorter, each process is under pressure, and the testing and debugging of its equipment is no exception. Because acceptance testing is the key to identify the possible deterioration of the operation status of the data center, the value of the test will only increase with time.

Planning the practicality of high efficiency and safety testing to ensure the implementation of the schedule, including the overall data management required to deliver the results of the organization on time.
If the test plan is completed, the parameters are set correctly, and the process has been verified, but these results are not available, then the work has not been completed. Pay attention to strict data management to ensure timely collection and recording of acceptance and reliability data. Productive data management practices include:
Specific field data coordination
• electronic information capture
• planning of proprietary systems
Shortening the testing time may increase the workload of data center tester, thus generating a large amount of data in a short time. Testing staff members need to focus on capturing data and ensuring that they are provided in an organized way. This requires on-site data administrators to improve the efficiency of the testing team and ensure that the data will not be misplaced or misunderstood.
Special data administrators can also improve the efficiency and timeliness by preparing the required knowledge base through communication center and professional system data.
Enhanced data management tools increase the speed and bandwidth of testing. The ability to test at the scene should be supported by on-site tools to capture information electronically. Removing files from files can reduce transmission and data entry errors and speed up synchronization with proprietary systems. Knowledge of data systems required by all parties is the key.
Organizing test data to suit each stakeholder system, as well as each reporting and compliance requirement, is the primary requirement for unique expertise. If the contractor is in need, the electrical test partner should also be able to provide an alternative to the proprietary system.
Planning cooperation to alleviate the pressure of time
Data management is a good example of coordination between major contractors, commissioning agents and electrical testing teams. The communication may require some time from the main contractor: because the test team needs to get more information, more information needs to be reiterated for verification. The team with forward-looking thinking will share responsibility with the contractor. By reducing the need for repetition and transmission of knowledge, the contractor can save more time, and the test provider can respond to needs and changes more quickly and more flexibly.
Even the best plan can change. Acceptance and reliability testing also require flexibility, and a test company should be able and willing to assume ownership of this flexibility, so it does not have a negative impact on the timetable or budget. The key factor in the plan is extensibility. If more resources are needed, commissioning companies should be able to expand testing, data management and reporting to ensure the implementation of the plan.
The cost of extensibility is also a factor. Testing companies should consider the reasonable assessment of the time required for technicians and teams. But flexibility and extensibility are not the main concerns of testers.
Test at a safe speed
Testing of distribution assets and systems can proceed safely according to schedule. Testing companies with rich data center testing experience will have internal security policies and procedures that meet or exceed OSHA and NFPA standards, while maintaining an efficient timetable, but they should also have the ability to meet specific site or customer specific security requirements.
Testing companies should have a reliable culture of safety. A key indicator of its safety culture is related safety certification. It believes that strict training will be required for certification of the company and technical personnel. The third party requirement of NETA certification also guarantees an independent, factual result, which can detect problems immediately and handle them in time.
Although the human error rate is 22% in the data center downtime statistics, the failure rate of other categories (including UPS failures and other problems) is obviously higher. The data center test should solve the problems in the construction process, but good test partners can also perform the switch correctly. Clear and accessible data and recording processes enable operators and maintenance teams to provide the necessary tools for the normal operation of data centers.

How does a website design a regular company to choose?

Website design, in this era of big data and cloud computing, the design of the website is related to the future development of the enterprise, and the design of its own website is the first problem that the enterprise is facing. In order to keep up with the pace of the Internet age, enterprises need to design their own websites, at the same time, in order to have a high quality product, to provide a web site for the development of the enterprise, the choice of a good website to build a regular company is also the most important. There are numerous websites in the market. How should we choose and judge a website to design a regular company?

First, whether there is a good work can let you see
Excellent work is often the best way to embody the ability of a website team. It is unrealistic to design a good website by just a few words. Whether it is a website building a regular company or a studio, there will be a reference case for customers to see, even if there is no online site, also should be deployed in the local site. If it doesn't even,... (omission of several possibilities).
Two. Is the team level of the construction station pass through
First of all, designers, designers are very important, excellent designers are often able to design web pages that conform to the style of the enterprise, such a web page can often give visitors special feelings. Then there's the technology problem. The technology currently used for web sites is PHP and ASP, but "PHP is the best language in the world". Can the construction team undertake big projects, such as ERP, such as B2C's multi-user mall. If it is this kind, it is recommended to cooperate with the professional website to build a regular company, just like the choice of the server, the server is the house bought for the website, the security is not safe very important, so most select the well-known, strong IDC supplier. In addition, the building team must know how to edit and understand the web site optimization so that it can design a website that is beneficial to the optimization of the web site, and a site that is not conducive to optimization is a pile of cost code.
Three. Is the security of the website guaranteed
Is that the means of protection in the network company, if the program can not even protect the most basic attacks, do you dare to use him? Website security is mainly related to two aspects, one is server or cloud host, the other is website program. Two. There are some website programs that have some holes that are not solved. You can let the building station produce a monitoring report of the 360 security testing platform, which can be detected.
Four. See if the system backstage is easy to operate
Some website design backstage design is very bad for operators to operate, especially when publishing news, publishing products and updating column contents. The website of a company beside me is made by a company that uses ASP to build a station. It is said that after months of work, there are still a lot of problems. Background operation is very inconvenient. A convenient backstage can be quickly operated without training.
Five. Look at the technical support of after sale
After the web site is online, there will be some problems, such as pages disorderly, pages can not open, or according to the actual needs to do some appropriate small changes, such as changing a navigation color. No matter what the problem is, the response speed of the website building a regular company is very important. How can the building party's after-sale technical support be difficult to say, in addition to the commitment of the building party (often signed a station agreement to determine the functional requirements, the time of work, price and other aspects), only customer feedback can be referred to. Of course, when people read countless people, people will feel relieved at the first sight.

機房建置,如何顛覆機房空間建模嗎?

如今,機房建置行業人士對於計算流體動力學(CFD)在機房空間的空氣分佈建模中的應用觀點傾向於兩極分化。其反對者強調CFD的侷限性在於機房空間的現實複雜性,而其支持者則認爲CFD應用實用高效。

然而有趣的是,雙方都認爲計算流體動力學(CFD)的建模和所提供的信息與數據中心模型師做的一樣好。而支持者將CFD建模軟件視爲一種工具,可以將其應用於數據中心機房空間空氣分佈的建模。
CFD建模
人們希望通過CFD評估機房容量管理的量化結果,而不是僅僅爲了建模,通過採用CFD建模來爲數據中心項目帶來價值平衡。
首先查看一下其應用動機。以下的數據中心設計指南提出了數據大廳區域內的CFD建模:
•CFD被提名爲“測試各種設計佈局和配置的可行方案”(ASHRAE這樣數據通信設備中心設計考慮,第二版)。
“爲了獲得最佳結果,需要結合使用CFD建模系統和電力和冷卻功能”(ANSI / BICSI 002 - 2014數據中心設計和實施最佳實踐]。
•考慮用於大型數據中心的計算流體動力學(CFD)模型,以優化電信路徑、空調設備,設備外殼,迴風口,通風口和通風磚的位置(TIA標準TIA - 942 a數據通信基礎設施標準中心,2012年8月)。
這些建議是促進機房空間CFD建模作爲最佳實踐的強勁的推動力,並提示將CFD建模應用於數據中心機房空間(如測試和優化設計)所帶來的益處。但是這些建議也提出了以下幾個關鍵問題:採用CFD分析是否會產生這些好處,這些好處究竟是什麼?
要回答這些問題,需要考慮CFD建模本身.CFD建模軟件是一個可以預測數據中心氣流和溫度分佈的一組方程的工具。該工具將由CFD從業人員根據應用來量身定製。
在ASHRAE這樣rp - 1133”如何驗證和報告室內環境建模CFD分析”或CIBSE AM11”建築性能建模”內容中可以找到CFD建模應用於環境建模的指導。儘管這些文件提供了關於應用CFD的內容,但這個指導並不是針對機房空間的氣流模型的。
ASHRAE這樣研究項目rp - 1675”數據中心CFD建模指南“預計將產生數據中心特定的指導方針和基準,這將有益於此類應用。此外,使用數據中心特定的CFD軟件可以明確幫助捕獲關鍵的建模方面,例如泄漏路徑或地磚。這足以獲得數據中心機房空間的CFD建模的價值嗎?
在專家看來,獲得CFD建模價值的關鍵在於,如果不是爲了獲得差價合約報告而進行的,CFD實踐者對項目的理解並這種理解轉化爲正確模型的能力。在這方面,可以採用從環境模型開發和評估中的十個迭代步驟中獲得靈感的方法。在進行建模之前,確定以下內容並與項目團隊分享:
(1)建模目的。
(2)性能指標和驗收標準。
(3)模型的關鍵特性。
在數據大廳設計的背景下,CFD建模目的通常是確認冷卻系統是否能夠向它設備輸送足夠的空氣。其性能指標可以基於它設備入口空氣溫度,機櫃前端溫度或服務等級協議(SLA)中指定的溫度傳感器位置。這種模型的關鍵特徵之一是確保它捕獲冷卻系統設計中使用的元素,並因此與設計基礎保持一致。
雖然這不一定會改善建模本身,但它確保進行建模的人員對模型的意圖有着透徹的理解,並且在開發模型時能夠捕捉到這個意圖。這也使得CFD建模研究成爲關於數據大廳氣流管理的一些關鍵方面的討論:平衡冷卻氣流的需求和供應,空氣泄漏管理,控制策略。而這些將成爲討論優化策略的共同基礎,例如用於氣流管理的冷卻單元和擋板的定位。
在許多情況下,還需要討論研究的情景。這個討論集中在諸如“這是最壞情況”,還是“這種故障情況有多大可能”等問題上,雖然建模用於量化影響及其嚴重性,但對概率的評估超出了團隊的建模和參與範圍,客戶需要明確界定風險水平。根據當時可用的信息,這是決定是否在部分負載或在完全佔用空間下分析機房空間的決定。
數據大廳CFD建模研究的價值在於如何建立設計的信心。根據人們的經驗,這是通過對建模進行教育來實現的,不僅包括其優點,還包括其侷限性。當CFD建模工具以這種方式接近時,它提供了很多對氣流和冷卻特徵的獨特見解。

Datacenter migration，How to choose a hosting partner?

Datacenter migration，The latest survey by MarketsandMarkets, a research agency, predicts that the size of UC and the general collaboration market will reach $6 billion 200 million in 2022, so companies are working to develop tools to help customers implement these productivity and increase their income. But even if the industry is interested in the capabilities of the device, the problem remains, and that is how to choose a data center partner hosting the platform.

Improper selection of Data Center partners may lead to poor connectivity, limited infrastructure, or limited opportunities for future business growth, causing enterprises to lose profit in the competition. Therefore, when choosing multi service data center partners, we need to consider the following points:
1. corporate reputation
Enterprises need to consider some initial problems when choosing data center providers. First of all, providers should enjoy a good reputation in the industry and have a good track record in successfully deploying solutions. Each company is unique in its approach, so it is also important to have a full understanding of its functions, including the level of SIP protocols and connection infrastructure and the data center layer they provide, so that the enterprise needs to understand the reliability of the architecture.
There is no bad communication between enterprises and the existing customer base of data center providers, which will help to confirm their industry reputation and service capabilities and enhance the overall awareness of data center providers.
2. end - to - end stack ownership
Enterprises should look for a data center provider to invest in building and operating infrastructure, data centers and connectivity capabilities. Under normal circumstances, enterprises invest in solutions involving multiple providers, which only increases complexity and cost.
Suppliers who can provide complete stack of communication and terminal will provide higher efficiency. This is because they can make more control over all aspects of quality and delivery, so that the provider can provide a higher level of service level agreement, and the enterprise can benefit from it.
3. technical strength
Enterprises should also work with data center providers with some key technical functions, such as providing comprehensive security coverage capabilities, allowing them to create network abstraction layers that can run multiple independent solutions to enhance the security of the physical network.
In addition, enterprise selected data center providers should have managed and supported SIP, connectivity and session boundary control (SBC) clusters that provide the highest level of bandwidth, call quality, scalability, and minimization of network and service interruptions. They should also have a powerful multi protocol label switching (MPLS) infrastructure for WAN connections, which will ensure that their selected data center providers can take advantage of the latest technologies and handle connections across multiple communication media.
4. the elasticity of change
With market integration becoming more and more popular, enterprises' partners do not want to be in the predicament of being bought or completely stopped. Therefore, enterprises need to focus on providers that provide data centers and full sets of products that are resilient in any case, and can use hybrid solutions, high-level disaster recovery strategies, and flexible hierarchical services when needed.
In addition, in a rapidly developing market, it is important for an enterprise to assess whether a provider has the risk of being acquired or merged. Providers should have financial security, which can reduce the possibility of financial risks and ensure continuous investment in research and development of products and surrounding infrastructure.
In a word, enterprises need partners to deal with all transactions such as development, implementation, training, trusteeship, and so on to enable them to implement future protection of the business without the complexity of the services of multiple providers. At the same time, it provides better transaction, higher efficiency, service delivery and support, migration and renewal for enterprises.

What are the key points of the website's website design?

Website design, in the era of rapid development of the Internet, the enterprise website is not only a knocking brick in the Internet service, but also represents the facade of the enterprise. Whether it is online or under the line, with the continuous rise of the logistics industry, there is no need for face-to-face exchange and face-to-face delivery. And in the middle, the enterprise website is the best embodiment of corporate image. Therefore, the design of a website is particularly important for the development of an enterprise. What are the key points of the website design? What elements do website website design enterprises need to pay attention to?

1, the website itself server:
The website's own server is very good and bad, this is why put this in the first place, generally speaking, as an enterprise, the web server is particularly important, because it involves the security of the company's network information.
2. The program of the website:
The website design enterprise thinks that a website is not judged by the appearance of a web site. It is called "the bustle of the outsider and the doorway". A good programmer has the ability to write a strong program. If the enterprise is not lucky enough to choose a network company without hard strength, It will be able to bring due role for the future enterprise website can bring due effect, the situation will probably have: the site is attacked, the website is bad information hanging chain, even the website directly collapse, if a business website appears such situation, for a business can think of the negative impact of how big!
3. The building of the web site framework:
A web site that looks simple, depends on the designer's rational planning framework, and some of the websites look very tedious, and they can't give the visitors a good experience, and they may also cause a slow load.
4, web page beautification processing:
Web site design companies believe that the first time to give people visual impact, the processing of non image material is the so-called "giving people a sense of the moment." It is just that sometimes the feeling of being so bright makes visitors feel favorable and stickiness to the website.
5. Content filling of the website:
The website, like a person, not only has a beautiful skin, but also has a deep connotation. It is a nice "skin bag and an interesting soul". If your content is not attractive enough, the good feeling of the website will be discounted. Even more outlandish is that some web sites are written on the lips of the donkey.

機房建置網絡安全演變:下一步趨勢是什麼?

機房建置,數據中心可以當之無愧的說是企業業務運營的神經中樞。企業業務的成功最終需要取決於數據中心的彈性和安全性。伴隨着當前的網絡安全威脅形勢變得越來越複雜,企業組織正被迫將安全保護分層到他們的數據中心基礎設施中。

在本文中,我們就將幫助廣大讀者諸君瞭解當前市場上正在發生的變化,以及企業亟待進行哪些方面的考察,以便能夠充分利用貴公司數據中心的安全保護。文章中,我們將爲您介紹在對數據中心安全產品之間進行比較時,需要考察的五大關鍵領域。
現如今,應用程序經濟已經將幾乎每家企業組織都變成了一家軟件公司,這種轉變推動運行企業所有軟件的數據中心開始擔任更爲關鍵性的角色。數據中心越來越成爲企業業務運營的神經中樞。而最終,企業業務的成功則需要取決於數據中心的彈性和安全性。
這就是爲什麼當前越來越多的企業組織爲了保護數據中心資產而投入比以往更多的資金並不奇怪的原因所在了。數據中心網絡安全預算的增長速度遠遠超過了其他那部門。根據最近的調研數據顯示,僅在2016年全球數據中心安全市場價值就已經達到61.5億美元,預計2022年將達到約141.1億美元,2017年至2022年期間的複合年增長率爲14.85%。
由於虛擬化的數據中心,混合雲和軟件定義的網絡模糊了現代數據中心的界限,使得業界目前對於數據中心安全性的投資均旨在應對當今基礎設施日益複雜性的問題。與此同時,隨着網絡安全攻擊者不斷調整其逃避技術,以避開現有數據中心的安全技術,使得企業數據中心的安全保護策略始終處於不斷變化之中。
●2017年,在74個最常見的漏洞攻擊工具和有效載荷感染路徑中,99%使用了逃避技術。
●網絡安全攻擊者每天發佈新的惡意軟件樣本數量高達360000個。
●數據泄露總數超過1.74億,平均違規成本爲360年萬美元。
隨着企業客戶逐漸開始調查數據中心的安全選項,以應對當前的這些安全風險,他們需要了解市場中正在發生的相關變化。曾經構成單一產品的功能:如數據中心防火牆(DCFW)或數據中心IPS(DCIPS)現在已在其他產品中發現,因此隨着新的子類別的出現,更難對這些產品進行一對一的比較,因此,企業採購人員需要明確相關的事實和確定的基準來比較具有類似配置的類似產品,以便能夠爲他們所在企業的具體使用案例挑選最佳產品,並將其用於實踐過程中的概念驗證測試。
數據中心網絡安全的演進
隨着當前的網絡安全威脅形勢變得越來越複雜,企業組織正在被迫將安全保護分層到他們的數據中心基礎設施中。而DCFW和DCIPS所提供的功能對此至關重要。
DCFW的目標首先是在兩個網絡之間實施訪問控制策略。防火牆已從早期的數據包過濾和電路中繼防火牆發展到應用程序層(基於代理)和動態數據包過濾防火牆,但其基本目的是保護可信網絡免受不可信網絡的侵害,同時允許授權通信在它們之間傳輸。
而DCIPS的目標是識別和阻止針對數據中心資源(如Web服務器,應用程序服務器和數據庫服務器)的攻擊。這些產品不斷髮展,以保持捕獲日益複雜的攻擊的平衡,同時產生幾乎爲零的誤報,並滿足嚴格的網絡性能要求。
鑑於企業組織以前傾向於採用差異化的單一產品DCFW或DCIPS來提供阻止或過濾功能,現在有些企業正在尋求一種可以執行訪問控制和深度數據包檢測的單一平臺,以保護服務器應用程序免受遠程攻擊。
因此,即使DCFW和DCIPS演進到具備下一代的相關功能,市場上仍然出現了一類名爲數據中心安全網關(DCSG)的新產品,這類新產品將DCFW和DCIPS的下一代功能進行了結合。與保護用戶免受互聯網干擾的下一代防火牆(NGFW)不同,DCSG通過互聯網保護數據中心資產資源,例如網絡服務器,郵件服務器,DNS服務器,應用程序服務器等。
理想情況下,DCSG旨在對所有數據包和端口以及所有協議執行深度數據包檢測,以確定哪些應用程序在哪些端口上運行,從而有效保護它們。這應該注重性能,提供安全性,同時保持應用程序的平穩運行。
數據中心網絡安全概述
單一平臺的部分吸引力在於其可管理性因素,企業組織可以通過單一平臺跟蹤和控制應用程序的性能和安全性級別。事實上,隨着越來越多的企業組織要求簡化數據中心的安全控制,未來,這一新類別可能會包含網絡應用程序防火牆(WAF)功能。
那麼問題是,一家企業組織是否可以取消其DCFW和DCIPS設備,以支持單個DCSG呢?在很多情況下,的確是可以的。但這並不一定意味着對單一功能的數據中心安全設備的需求正在消失。他們將繼續發展,以供企業組織在某些有限的使用情況下的使用。
例如,一些企業組織可能會用位於其數據中心邊緣的融合多功能DCSG取代單功能DCFW和DCIPS。然而,他們也可能選擇在數據中心周邊背後部署DCIPS(即,作爲“線路中的碰撞”),以實現細分和深度檢查功能,而不會帶來路由防火牆的複雜性。
這些新的DCSG產品要求那些負責獲取數據中心保護技術的人員爲其評估過程帶來新的紀律。企業採購人員需要了解獨立產品與新融合DCSG產品之間的差異,以便有效評估產品,並確定適合其所在企業組織的合適性。
充分利用數據中心安全保護
數據中心網絡安全設備可處理正在訪問服務器場中大型應用程序的數十萬用戶的流量。應用程序流量爲每個請求生成很多連接和事務,這對網絡安全設備快速建立多個連接,保持許多連接打開,並實現高吞吐率的能力提出了很高的要求。
最終,企業組織需要獲得充分的可視性和控制,不僅僅是周邊的數據,而是在整個數據中心邊界上流動的數據。
DCSG必須能夠執行訪問控制和深度數據包檢測,以保護服務器應用程序免受遠程攻擊,並且他們應該瞭解網絡分段需求。他們還必須抵制真實的攻擊者繞過安全技術的迴避技術。
同時,這些保護措施必須在不影響數據中心運行的服務器和應用程序的情況下實現交付。由於受DCSG保護的服務器和應用程序的性質,高可用性,低延遲和容錯性是關鍵性的任務。
一對一的比較:衡量數據中心安全產品
安全產品的評估應始終基於具有類似配置的類似產品類別。當企業的採購人員評估數據中心網絡安全產品時,他們必須確保他們所選擇的DCSG產品能夠相互融合(即DCFW產品應與DCFW產品進行比較,DCIPS產品應與DCIPS產品進行比較),並且所有產品的設置均是一致的。
例如,如果安全旁路模式默認情況下在一個產品上啓用,而不是在另一個產品啓用,其可以提供增強的性能統計信息,但代價是允許未經檢查的流量進入網絡,而管理員對此並不知道。
這可能會在POC期間歪曲比較,這個例子強調了安全有效性和性能之間的動態關係,在評估任何安全產品時必須牢記這一點。
企業組織評估數據中心安全產品時,應該嘗試使用以下5個類別中的某些基準測試,並對產品評分(以DCSG爲例)。這樣做將建立一個強有力的比較矩陣,以決定爲POC提供哪些產品。
安全有效性
DCSG產品應在防火牆策略執行和ip流量檢查中進行安全有效性評估,同時牢記各種條件下的穩定性和可靠性。
企業數據中心應測試防火牆的功能,以查看設備如何在不同信任級別的不同區域之間執行策略。還應該測試IPS功能,以查看設備使用調整策略阻止惡意流量的情況,但是測試時公衆可以使用簽名。
防火牆有效性測試
至少,防火牆必須提供可信的內部接口和不可信的外部/互聯網接口。
企業通常會制定相關的策略以允許或拒絕來自以下一個或兩個區域的網絡流量:
●不受信任,通常是外部網絡,並且被視爲未知且不安全。互聯網就是一個不可信網絡的例子。
●可信任,通常是企業內部網絡,即被認爲是安全和受保護的網絡。
理想情況下,測試應驗證執行策略的性能和能力,以執行從受信任區域到不受信任區域,以及從不受信任區域到受信任區域的流量策略。
IPS有效性測試
在典型的企業中,安全工程師們通常會調整IPS,以確保其保護範圍與其所處環境的需求相匹配。因此,應該使用調整後的政策來測試安全有效性。
IPS的有效性應該基於產品阻斷現實世界的能力來進行測試。這包括一系列的漏洞和有效載荷,其中包括:
●返回一個反向殼
●在目標上打開綁定外殼,允許攻擊者執行任意命令
●執行任意代碼
●安裝了惡意負載
●系統無響應
使用一系列的漏洞和有效載荷,你企業的測試應該建立一個比較產品的整體阻止率(塊)。
由於許多較早的應用程序,操作系統和攻擊仍然在流通並保持相關性,因此使用面向較舊漏洞的攻擊測試IPS有效性,並根據漏洞年份來衡量漏洞可能很有價值。
此外,根據漏洞攻擊的影響來衡量IPS覆蓋率可能很有價值:
●最嚴重的漏洞攻擊是導致遠程系統泄密的漏洞,爲攻擊者提供執行任意系統級命令的能力。
●稍微不那麼嚴重的攻擊會導致單個服務的破壞,但不會導致任意的系統級命令執行。
●最後,導致系統或服務級別故障的攻擊會導致目標服務或應用程序崩潰,並需要管理操作來重新啓動服務或重新引導系統。
根據漏洞利用效果比較有效性可以提供有關設備安全功能的寶貴信息。
穩定性和可靠性
當組織評估DCSG時,他們應該考慮這些設備在正常工作負載下如何保持長期穩定性,以及它們如何處理特殊情況(如電源故障)和擴展攻擊,如分佈式拒絕服務(DDoS)攻擊。不應考慮在惡意攻擊時無法維持合法流量(或崩潰)的產品。
DCSG的整體有效性應該使用一個公式來結合產品的防火牆有效性得分,IPS有效性以及穩定性和可靠性得分。
迴避技術
企業必須能夠依靠其DCSG來預測和識別專門設計用於逃避檢測的惡意活動。
迴避技術是在交付時僞裝和修改攻擊的手段,以避免被安全產品檢測和阻止。安全設備未能正確識別特定類型的規避可能會允許攻擊者使用設備假定具有保護功能的整個類別的漏洞。這意味着DCSG應該通過一系列的測試,使他們受到一系列通用規避技術的影響。在不充分考慮逃稅的情況下提供保護結果可能會產生誤導。
漏掉的類別越多(例如IP數據包碎片,流分段,RPC碎片,URL混淆和FTP迴避),設備的效率越低,例如,最好是錯過一個逃避類別中的所有技術,比如FTP逃避,而不是每個類別中的一種技術,這會導致更廣泛的攻擊面。
出於這個原因,在總體安全有效性評分中包含防規避結果是至關重要的。
性能
企業組織需要知道他們的DCSG是否能夠在支持關鍵業務應用程序所需的性能閾值內進行風險管理,因此,他們應該尋找與安全有效性指標並行測試的性能指標。這包括測量諸如原始數據包處理,延遲和最大容量等領域的性能。
總體擁有成本
負責DCSG採購的決策者必須考慮可能影響設備總體成本的四個因素。
●產品購買:購買產品需要多少成本嗎?
●產品維護:一旦採購了產品之後,供應商會如何收取維護,支持和更新費用
●安裝:買方承諾部署產品的一次性資源是多少嗎?
●維護:從供應商處獲得更新和補丁需要哪些資源?
在POC期間尋找什麼
顯然,即使是數據中心安全產品評估的早期階段,也需要深入瞭解設備功效所有領域的指標。市場上有相應的服務機構可以爲企業採購人員們提供實踐性的測試,比較類似測試條件下的產品性能,並使用類似的產品配置。
從實踐測試階段開始,企業的評估人員可以快速挑選候選產品,並在需要深入分析或專門針對其環境定製的測試領域啓動更爲密集的POC評估。隨着企業客戶將候選產品名單提交給POC,他們應該將重點放在若干領域,例如,當談到測試DCSG的防火牆功能時,他們應該進一步深入定製的數據中心訪問配置和內部網絡區域的部分分段。
關於IPS功能,他們應該測試產品如何處理內部攻擊行爲和橫向移動技術。
此外,企業客戶可能會使用POC來評估基於其更先進功能的設備的未來發展。對於某些情況,這可能包括應用程序服務器保護或WAF保護,以防止防火牆或IPS功能帶來太多延遲以適應應用程序(如在線交易)。對於其他一些企業而言,其可能是使用服務提供的雲平臺測試企業在場外的功能。

Datacenter migration, how to choose hosting service providers?

Datacenter migration, security, redundancy, connectivity, and many other matters need to be considered when an enterprise chooses to host a managed data center service provider with its IT infrastructure.

The managed data center service provider can allow the enterprise to fully control the hardware, while the hosting service provider is responsible for the physical security of the IT facility and the normal running time of the network. But how can a company choose a good hosting data center service provider?
The following are the five main points that enterprises need to pay attention to:
The 1. position is the most critical
A reliable data center should focus on the normal running time, and the location of data center construction and operation should play a key role in the decision-making process. Cooperation with trusteeship partners who strive for 100% availability should become a key priority.
The Tier 3 level data center has a 99.98% or higher normal run time, which is equivalent to an annual downtime not exceeding 1.6 hours.
It is important to take into account that the closer the data center is to the location of the customer, the lower the cost of the network, so it is often the best choice for the enterprise to choose a partner that can ensure the best location of a good network connection.
2. security and redundancy
Like any aspect of IT, security should be a high priority for enterprise hosting providers. In a practical sense, this means that we have a professional data center facility team that will monitor operational factors such as network access points, power supply and cooling all day.
Other resources in an emergency are also a symbol of a specialized partner, which means that the backup power that the hosting service provider deploys will provide additional redundant and unlimited power (UPS).
3. the power of communication
The choice of data center is not only the physical characteristics of the data center facilities, but also the staff of the operation. The way to achieve a good partnership between an enterprise and a trustee service provider is communication, which is also crucial for data security.
Whether the enterprise is to modify the protocol, report the question or direct the suggestion, the enterprise expects to get the all-weather support of the technical team of the partner, so as to realize the comprehensive understanding.
4. can be extended
Enterprises usually add server expansion capacity in their data centers, which means that more space, power and heat resources are needed at the physical level. A good hosting partner can provide more space options for enterprises to expand their business more flexibly when business grows. Similarly, enterprises only need to pay for their own services, so there is no risk of waste of resources.
5. flexibility and transitional services
IT runs fast and priorities change easily. Partners should be flexible enough to adapt to changing needs and provide additional services when needed.
This may mean the need to provide a managed service pattern that provides an advisory service for the enterprise's configuration or to provide a way to change the main service protocol (MSA) through the middle of the contract. Enterprises should make full use of the hosting services provided by trustee partners to ensure that their infrastructures can still run smoothly without any responsibility for them.
In essence, any organization that attaches importance to the normal running time of IT services will consider the above situation before moving a large number of devices and important data to new locations. Although these techniques and methods are not completely rigid guidelines, they are a good start.

The three features of a practical website design

In the era of rapid development of the Internet, website design has become a trend and indispensable condition. The website can not only be used as a platform for information publicity, but also can be used as a pluralistic flow of traffic. Not only can the business expand the business market, build the image of the enterprise, but also help the enterprise Dig out more potential customers. The enterprise design website also does not need to choose high priced stations only. Affordable website design can also bring a lot of benefits to enterprises. What are the benefits of that? What are the characteristics of affordable website design?

First, the features of website design

In China, people often misunderstand the Internet, thinking that e-mail is the Internet. We have seen many companies that use e-mail addresses as web addresses and print them on business cards. In fact, e-mail is just one of the most common and simplest functions in the Internet. The real meaning of Internet is the richness of its content, almost everything. For an enterprise, the symbol of its ability to communicate with the Internet is to have its own independent website rather than e-mail.
2, we can give a comprehensive and detailed account of the company and its products.
One of the most basic functions of affordable website design companies is to provide a comprehensive and detailed description of the company and its products. In fact, the company can put anything that people want to be known to the web site, such as company profile, company building, production facilities, research institutions, product appearance, function and use methods, all can be displayed on the Internet.
Two. The functional features of the website design
1. Product display
The products here can be physical or service. The product display module is mainly composed of three parts. One is to manage the product category. It can add, modify, delete, adjust the order, add subcategories, and support multilevel classification. The two is the product. The main contents of the product are product title, product category, product picture and product attribute. The product specification, custom sort, text content, in which the custom sort is used to set up the display order of the product, the text content supports the graphic and text mixing; three is the management product, which can carry on the inquiry, the content modification, the deletion, the recommendation, the downline and so on. I believe everyone knows about the definition of these operations.
2. Press release
Affordable website design news release module generally has three parts. The first part is the category of managing news. It can add, modify, delete, adjust, add subcategories, and support multilevel classification. The second part is the publication of news, general news headlines, categories, authors, sources, sort content and so on, and some custom sort functions. It is mainly used to set up the display order of the news, the text content supports the graphic and text mixing; the third part is the management news, and can query, modify, delete, recommend, put the top and down line of the published news.
Three. Design features of website construction
1, accurate design of website domain name guide enterprise brand
The concept of website design requires that users see the domain name of the site to be associated with the brand of the enterprise or product. According to the brand or name of the enterprise or product, the domain name can be conjectures. For different types of websites, the strategy is different.
2. Design the content of the website rationally and strengthen the brand of the enterprise
This concept requires the rational arrangement of the content to be displayed on the website, and to strengthen the brand through the display of information content such as brand, product, service and so on. For different types of websites, the strategy is different.

This concept requires the design of the website VI to fully reflect the brand, the user should be able to associate the website with the products of the enterprise or enterprise. For different types of websites, the strategy is different.

機房建置,軟件定義的分佈式存儲

機房建置,目前我們正處於一個新的時代,這個時代被賦予了許多標籤:互聯網+時,代雲計算時代,大數據時,代人工智能時代。

當前時代的它系統架構伴隨着軟件定義的發展,正發生着巨大的變化,作爲這架構核心數據保險箱的存儲單元正在面臨着前所未有的挑戰。前端業務應用規模從數據量、性能,安全性以及應用類型上都有了成倍的增長,傳統的存儲設備和解決方案很難滿足這種大規模應用場景的需求。不同的應用場景產生的數據類型及訪問數據的IO模型各不相同,採用軟件定義的分佈式存儲解決方案可以更好的應對目前的挑戰。
首先,我們需要知道什麼是分佈式存儲?
分佈式存儲
分佈式存儲是軟件定義存儲解決方案的實現,它是通過軟件將硬件進行抽象化管理,將集羣全部的CPU資源,內存資源,硬盤資源,網絡資源等進行池化,組合成統一資源池,然後通過簡單友好的管理界面或API提供給用戶個性化的存儲解決方案。
軟件定義存儲解決方案可以使生產系統在線運行的情況下進行縱向擴展(擴大)或橫向擴展(擴展),且存儲系統在擴展後可以達到容量與性能均線性擴展的效果。其具有以下特性:
高性能
分佈式存儲系統能夠將所有存儲節點的處理器資源,硬盤資源,網絡資源進行整合,將任務切分給多臺存儲節點,進行併發數據處理,避免了單個硬盤或設備造成的瓶頸,提升整個集羣的處理能力。分佈式存儲系統具有良好的性能擴展能力,可以滿足應用程序對存儲性能不斷增長的要求。
高擴展性
分佈式存儲系統通過擴展集羣存儲節點規模從而提高系統存儲容量,計算和性能的能力,通過增加和升級服務器硬件,或者指通過增加存儲節點數量來提升服務能力。分佈式存儲系統支持在線增加存儲節點,對前端業務透明,系統整體性能與存儲節點數量呈線性關係。
高可用性
分佈式存儲系統同時基於硬件及軟件設計了高可用機制,在面對多種異常時(如存儲節點宕機,網絡中斷,硬盤故障,數據損壞等)仍可提供正常服務,提高分佈式存儲系統硬件的可用性可以通過增加存儲節點數量或者採用多種硬件冗餘機制保證。分佈式存儲系統多采用副本機制或糾刪碼機制保證數據的高可用性,副本機制可以提供較高的數據冗餘度,但會降低存儲系統有效空間的利用率,糾刪碼機制可以在保證一定數據冗餘度的情況下,大幅提高存儲系統的有效空間利用率。
高安全性
分佈式存儲系統支持可靠的權限控制及互信確認機制,同時採用私有的數據切片及數據編碼機制,可以從多重角度保證集羣系統不受惡意訪問和攻擊,保護存儲數據不被竊取。
分佈式的“四高”特性,使得其在高性能計算,大數據視頻雲及大數據分析等應用場景中有着廣泛的應用。
高性能計算場景
在如氣象氣候,地質勘探,航空航天,工程計算,材料工程等領域,基於集羣的高性能計算,已成爲必需的輔助工具。集羣系統有極強的伸縮性,可通過在集羣中增加或刪減節點的方式,在不影響原有應用與計算任務的情況下,隨時增加和降低系統的處理能力。根據不同的計算模式與規模,構成集羣系統的節點數可以從幾個到成千上萬個。這些業務對後端的存儲系統提出了新的需求,包括統一的存儲空間,高效率的文件檢索,高帶寬的吞吐性能,高可靠的數據安全保障等。
大數據視頻雲應用場景
隨着視頻高清技術及超高清技術的普及,視頻大數據應用場景,如雪亮工程,平安城市,廣電媒資,影視製作,視頻網站等領域,對存儲設備提出了大容量,高讀寫性能,高可靠性,低延時及可擴展性等需求。針對這樣大規模視頻數據應用場景,就需要一個技術先進,性能優越的存儲系統作爲後端數據存儲的支撐者。
大數據分析應用場景
伴隨着互聯網技術及人工智能的發展,各種基於海量用戶/數據/終端的大數據分析及人工智能業務模式不斷涌現,同樣需要充分考慮存儲功能集成度,數據安全性、數據穩定性,系統可擴展性,性能及成本各方面因素。
在數據爆發增長的“數字時代”,軟件定義的分佈式存儲是存儲技術高速發展的結晶,並具有着很大的成長空間,必將應用於更廣泛的大數據業務場景。

Datacenter migration, how to reduce generator noise reduction

Datacenter migration, the principle of noise reduction in generator room by the noise processing company of generator set. The principle of reducing noise in diesel engine room is to ensure the ventilation condition of diesel generating set, without reducing the output power, using high efficiency sound absorbing material and noise reduction device to enter, exhaust air passage and exhaust system. The noise reduction is processed to make the noise emission meet the national standard (85dB (a)).

The most fundamental way to reduce the noise of the generator is to start from the sound source and adopt some conventional techniques to reduce the noise. Such as muffler, sound insulation, sound absorption and vibration isolation are the most effective methods.
1, reduce the exhaust noise. Exhaust noise is the most important noise source of the unit. Its characteristics are high noise level, fast exhaust speed and difficult management. The exhaust noise can be reduced by 40-60db (a) by using a special impedance muffler.
2, reduce the noise of axial fan. In order to reduce the noise of cooling fan, two problems must be considered, one is the allowable pressure loss of exhaust passage. Two is the required amount of noise. In view of the above two points, the resistive silencer can be selected.
3. Sound insulation, sound absorption and vibration isolation of the machine room
(1) sound insulation in the machine room. After the exhaust noise of the unit and the noise of the cooling fan are reduced, the main noise source remaining is the mechanical noise and combustion noise of the diesel engine. The method used is to remove the other windows except the necessary observation window which is connected with the observation room. All the holes and holes should be closed tightly. The sound insulation of the wall of the brick wall requires more than 40dB (a). Doors and windows of the machine room are fireproof and sound insulation doors and windows.
(2), air intake and exhaust air. After the sound insulation is processed, the ventilation and heat dissipation in the computer room should be solved. The air inlet should be installed on the same straight line with the generator set and the exhaust port. The inlet of the air inlet should be equipped with a hindrance muffler. Because the pressure loss of the inlet is also within the allowable range, the air volume in the machine room can be balanced naturally and the effect of ventilation and heat dissipation is obvious.
(3) sound absorption. The five walls except the ground in the engine room can be processed by sound absorption. According to the spectrum characteristics of the generating set, the perforated panel resonance sound absorption structure is adopted.
(4) the exchange of indoor air and sound insulation of the machine room will make the air in the room without convection when the closed water cooled generator is shut down, and the high temperature in the room can not be reduced in time. The problem can be solved by using the low noise axial fan and the hindrance muffler.
(5) the vibration isolation of the unit. Before the installation of the generator set, the vibration isolation treatment should be carried out strictly according to the relevant information provided by the manufacturer, so as to avoid the long distance transmission of structural sound and the continuous radiation of air in the transmission, so the noise level of the factory can not reach the standard. The vibration of the ground near the unit must be measured. If the vibration sense is obvious, it is necessary to carry out the vibration isolation treatment of the generator unit.
As a result, it can be seen that, after effective noise reduction, in order to make the room more beautiful and practical, it is usually decorated with microporous aluminum plastic punching plate outside the sound absorbing layer of the wall and the ceiling. At the same time, the lighting system is reasonably configured. So as to effectively reduce the noise of the computer room, and achieve a good noise reduction effect.

Enterprise website design basic issues that must be paid attention

Website design, in the background of the current Internet era, enterprises want to be based on the market, occupy a place in the network market, for the use of the network display is indispensable. When the enterprise uses the network platform to display its image, the website design is one of the most critical and direct ways. Although many enterprises will carry out their own website design, not all websites conform to the website mode. So, what kind of website is the most suitable business website? What basic issues should we pay attention to when designing website for enterprise website?

First, the choice of the domain name of the enterprise
Website building enterprise website design to apply for a domain name consistent with the enterprise name, is the premise for enterprises to carry out network promotion. The domain name is also the important network trademark of the enterprise. It plays an important role in the network marketing. When the name of the domain name is named, it is necessary to take into account the unification of the name and the logo of the domain name. A good domain name should be succinct, and it is difficult to remember to avoid too long characters.
Two, clear website planning
It is not difficult to establish an enterprise website. The difficulty is how to get good results after the website is launched. This requires enterprises to make a detailed planning for website construction. The location of different industries must be different, from page style design, staff arrangement, content setting to maintenance and update after completion.
Three. Pay attention to the originality of the article in the net
Original content plays a very important role in the optimization of the website. A good original article can ingeniously join a number of high quality external chains, which is very good for the search engine, especially Baidu. In addition, original articles can also enhance users' reading experience, increase clicks and keep regular visitors. If you can publish the original content regularly and quantitatively, you can enhance the ranking of websites. Therefore, it is suggested that enterprise websites should be updated frequently, maintained and published more original works.
Four. A planned release of the outer chain
Web site construction enterprise website production in the import link for search engine optimization is also very important, the same as the release of original articles, especially the new built site, do not have a large amount of release, and should be planned every time appropriate release, this effect will be better.
Five, appropriate network marketing
Display products, detailed information, contact mode, latest developments, online customer service, these elements are essential for most enterprise websites, and the network extension to other companies can be determined according to the company budget. This part is costly, but it can play a more rapid promotion effect in a short time.
After the success of a website construction enterprise website, it represents the reputation of the company, so the construction station is not equal to the end. After the establishment of the station, it needs to publicize the image of the enterprise, display or improve the competitiveness, seize the potential customers, let the website become a pool of "living water" is the enterprise managers must pay attention to.

機房建置,如何讓數據中心發揮最高性能

機房建置,正如美國橄欖球明星湯姆·布雷迪曾經說過的那樣,“如果不想獲得勝利,就不要打球”。這個咒語反映在布雷迪的TB12方法中,這是一個基於12條原則的整體生命週期,它構成了運動,訓練的充滿活力的最佳方法。其前提是在事件發生前阻止發生,並採取明智的,戰略性的預防措施。雖然不需要實施這12個原則,但是它們的效果是累積的:能融入的越多,其結果就會越好。

雖然這種方法適用於培訓高級運動員,但數據中心經理有其自己的一套原則來確保數據中心的最佳性能。稱之爲DCM10方法,每個數據中心管理人員都應該使用10個基本步驟來評估他們當前的數據中心,並幫助轉換其功能。與TB12方法類似,雖然並非所有這些步驟都是制定成功策略所必需的,但應用更多的最佳實踐將會帶來更高的性能。
爲了實現和維持數據中心的最佳性能,每個數據中心經理都應該遵循以下10個步驟:
1 .利用混合環境
它通過爲企業的基礎設施混合使用各種解決方案,企業應該獲得更好的可視性和控制權,以訪問關鍵的洞察力。無論是內部部署,託管數據中心還是雲計算,達到最高性能意味着創建靈活,可擴展,可持續和可靠的數據中心,以滿足當前和未來的業務需求。
2 .優化電力和冷卻設施
大多數使用高密度服務器的企業正在產生大量的熱量,並且比傳統老式設備消耗更多的電力。隨着新技術的進步,如大數據和機器學習,這種功率和隨後的熱量增加只會增加。由於典型機架的功率密度範圍從5千瓦到40千瓦不等,數據中心管理人員需要制定新的程序和軟件,以獲得預測新發現的冷卻要求的實時見解。
3 .開始思考綠色節能
除了監測電力和製冷之外,數據中心管理人員應評估“綠”色替代品以提高能源效率。通過使用風力發電或太陽能電池板等可再生資源,企業可以將其數據中心戰略轉變爲包含環保實踐,並優化其現有數據中心基礎設施。
4 .進行自動健康檢查
通過持續的分析,診斷和修復,數據中心管理人員可以定期進行健康管理檢查,以解決代價高昂的停機和中斷風險。通過持續監控數據異常情況或潛在威脅,企業可以通過規劃和解決系統內可能發生的任何問題來保護其設施,以幫助自動化業務流程。
5 .採取積極主動的立場
除定期的健康檢查外,實時監控企業的數據中心還可讓工作人員做好最壞的準備,並採取積極主動的態度應對任何不可預見的威脅,例如自然災害。這意味着要從數據中心的日常性能到制定災難恢復計劃等任何事情都有可能發生衝突。
6 .平衡預算
如果沒有最新的數據中心設施和它設備,組織可能會落後於直接影響其業務成功。由於它預算中只有一部分專用於數據中心,數據中心管理人員必須首先保持功能,效率,空間之間成本的平衡,並且只實施與其數據中心的性能,可靠性和敏捷性直接相關的智能升級。
7 .獲得高層管理人員的支持
企業的數據中心戰略中最大的一個脫節就是沒有獲得高管的支持。爲確保成功部署數據中心管理,整個團隊(它經理,系統架構師和企業高管)必須共同協作,才能充分利用解決方案堆棧。
8 .評估管理流程
部署數據中心管理解決方案的組織可以自動化變更管理流程區域,並記錄設備中所做的任何更改。這意味着要實時瞭解如何管理變更,變更的影響以及變更何時完成。對於沒有使用DCM解決方案的公司來說,這是一個人工的,時間密集型的過程,它佔用了數據中心管理人員的寶貴時間。
9 .確保靈活性和可擴展性
數據中心管理人員必須能夠根據需要擴展其部署,而不受當前硬件或軟件的限制。這意味着不用擔心引入新的解決方案,如現場可編程門陣列(FPGA),可以爲特定的工作負載或應用量身定製計算能力,從而提高靈活性和可擴展性。
10。始終位於行業前沿
無論是增加邊緣計算來卸載依賴延遲的服務,還是結合人工智能解決方案來檢測任何問題,在當今快節奏的商業環境中,保持行業領先地位至關重要。儘管沒有人能夠預測未來的發展,但實現數據中心戰略的現代化將確保企業保持領先,而不是落後一步。

Datacenter migration how to choose a managed service providers?

Datacenter migration，When enterprises choose hosting data center service providers hosting their IT infrastructure, they need to consider security, redundancy, connectivity and many other things.

The managed data center service provider can allow the enterprise to fully control the hardware, while the hosting service provider is responsible for the physical security of the IT facility and the normal running time of the network.

5. flexibility and transitional services
IT runs fast and priorities change easily. Partners should be flexible enough to adapt to changing needs and provide additional services when needed.

In essence, any organization that attaches importance to the normal running time of IT services will consider the above situation before moving a large number of devices and important data to new locations. Although these techniques and methods are not completely rigid guidelines, they are a good start.

What are the contents of the enterprise service website design?

Enterprise website design, not only refers to the design and management function, program construction of every web page, but also a lot of related service projects. It is a long-term process. During this period, every service may meet different problems to be solved. Only by understanding these can we manage a good website better. What are the specific aspects of the website design and what related problems will be encountered?

1. The website design this content
In addition to planning, design, cutting, program, content editing, quality inspection and other websites to make their own work, as well as web site production, such as website space and domain name selection, website filing, keyword selection and layout, mobile site docking WeChat interface, through the WeChat menu direct access to the mobile site, To help enterprises get through the "three networks one" marketing mode.
Site space and domain name selection, this can not be selected casually, the size of the site space needs to consider the long-term development of the enterprise, but also to consider the speed and stability of the operation, the domain name of the website must consider optimizing and user experience, choosing the domain name related to brand or product, key words selection and layout are very important. Directly affect the accuracy of keyword ranking and traffic in the later stage.
2, the issue of the website after sale
After the sale of the traditional website, there are only some simple modifications to the website, and the others are gone. In fact, the content of the website after sale, such as: domain name, space management and maintenance, if the domain name or space problems, will seriously affect the user experience and website search engine optimization; the later minor revision of the website, help the enterprise to replace the advertising map, timing data timing backup, even if problems occur. Can immediately restore the latest data, otherwise the web site optimization for a long time, updated a lot of content, no backup, it will be very troublesome; Web site on-line special training to help enterprise operators to quickly master the backstage operation, once, multiple retraining, for your company's website to do operation diagnosis and so on.
3. Website operation training
This is the urgent need of the enterprise, many enterprises do not start network marketing, the main is that the website operators are not in place, not without recruiting people, but not people, especially those in remote places, more difficult to recruit people, then network marketing will not do it?

機房建置:DCIM讓首席信息官不再擔心宕機危機

機房建置,如今,很多組織在數據中心投入的資金讓其首席財務官(CFO)望而生畏。數據中心基礎設施的設置,數字驚人的電費賬單,維護和升級的成本,以及日益昂貴的那人員開支,這些對於組織來說,都是不堪重負的巨大支出。而企業首席信息官和數據中心管理人員最爲關注擔心的是停機時間,特別是正在實施關鍵任務時。

“關鍵任務”的規模無關緊要
無論是隻有幾個機櫃的服務器機房,還是部署數千個機櫃的獨立設施,數據中心都必須整體運行,其系統和部件必須全天候可用,效率高,並且需要妥善管理。而電力中斷或停機對業務運營影響巨大,必須保障持續運營。
DCIM:每個數據中心都需要的工具
數據中心信息管理(DCIM)工具已經證明可以解決組織迫切的管理需求,並提供了一個當今數據中心必不可少的監控維護工具。這些集成的業務工具可以自動監控數據中心的運行情況,幫助管理人員降低能源和維護成本。從首席信息官的角度來看,DCIM可以幫助數據叫主管理人員和運營商衡量其容量,準備情況和易受宕機的風險。
組織採用適當的DCIM工具,可以爲數據中心運營的最爲苛刻的關鍵任務做好準備。數據中心的它系統,設備和軟件必須進行有效和經濟的管理。這意味着管理人員對機械,空間,電力和冷卻系統必須保持高度關注,以確保其可用性和可持續發展目標。採用有效的DCIM工具,可以充分利用現有的監控程序,以確保數據中心管理人員能夠以最高的效率獲取,存儲和分析運營數據。
快速反應機制
數據中心是不斷變化的實體,可以說每時每刻都不一樣。而設備的添加和升級不斷改變數據中心的運營態勢,例如雙絞線,光纖接線板,路由器,接入和匯聚交換機,電源插板或PDU,特定應用服務器,以及存儲單元等。
系統限制通常決定工作人員如何熟練地進行這些更改。而適當的DCIM工具爲系統管理員提供可操作的可靠信息,以確保這些更改和升級得到正確實施。組織的目標是讓系統保持準備就緒狀態,並在發生停電或故障時迅速作出響應。
監視使用情況和性能
藉助適當的DCIM工具,數據系統管理人員可以獲取實時性能數據,以便重新定位系統和設備。這其中包括趨勢,使用數據和具體指標,這些可以證明組織的首席信息官和首席財務官的價值。
監控各級設備的性能可以提供數據中心管理人員所需要的警報和系統配置文件閾值,以保持最佳效率。管理人員可以通過他們的筆記本電腦通過中心工作站了解系統,房間,特定行或甚至單個機櫃的狀態。這允許組織提前計劃可能會對數據中心及其運營就緒產生重大影響的更改。
管理設備和系統
當今強大的DCIM工具提供的關鍵優勢是庫存管理。適當的DCIM軟件可以高效地構建中心物理設備的數據庫。這可能包括設備製造商,組件,安裝日期,機櫃位置,設備位置,電源連接,功率消耗,網絡連接類型和數量等。掌握了這些信息後,管理人員可以對數據中心的能力做出明智的決定,以及瞭解添加,替換和升級如何影響其準備就緒和易受宕機事件的影響。同樣重要的是,這些信息在確定漏洞和恢復方面時可以證明是最有價值的。

Datacenter migration,optimization and management technology

Datacenter migration,After treated with caution and suspicion alone for a long time, more and more data center operators are deploying data center infrastructure management (DCIM) software, this software not only help them to monitor the operation of the data center of critical infrastructure, also help to optimize data center operations.

And more and more enterprises are pushing the application of DCIM further.They are using a new type of data center management software that pushes the functionality of the DCIM beyond the boundaries of infrastructure management to achieve end-to-end efficiency, flexibility, and competitiveness.This new software category is called data center service optimization (DCSO).
Beyond the DCIM
DCIM software can be regarded as a modern management tool for data center operation.Although many DCIM products have been on the market for more than a decade, their adoption rate is still very low.According to 451 Research, a Research firm, only about 15% of the data centers with power capacity of 3MW and above deployed DCIM software.Many data center operators refuse to deploy DCIM, in part because DCIM often requires operational changes that make software costs far more than they buy.
But those with DCIM will be one of the best and most efficient facilities in the industry.The DCIM platform includes monitoring, asset, change and capacity management, which can obtain data on power, heat dissipation, space and connectivity.Operators use DCIM software to understand and predict the data center facilities throughout its life cycle in the performance, for the IT services growth to achieve the accurate cost calculation and key infrastructure planning.
Although its application is still in its early stages, DCIM's data and functions are increasingly being used in physical infrastructure such as power, cooling and space.People are beginning to see new data center service optimization (DCSO) products using DCIM and its underlying data to achieve new optimizations, services, and business-oriented capabilities.The data center service optimization (DCSO) product expands the capabilities of the DCIM to manage physical assets and virtual assets within the data center and geographically dispersed facilities.
DCSO applies operational data to IT decisions.
By combining a series of DCSO and other tools and subsystems, data center managers are implementing greater infrastructure and IT monitoring, management, and control.These integration tools are increasingly being used to provide the end-to-end view of delivery of IT services clearly, accurately, and in real time.In some cases, the effective use of DCSO and other software can reduce the risk, avoid the failure point of the workload, and reduce the demand for peak power supply.In this way, data center hardware and infrastructure and human capital costs may be reduced.
Today's DCSO products are combining DCIM data with IT systems management (ITSM) and virtual management (VM) management systems.The goal is to more closely match IT service requirements with the supply of physical data center resources (power, refrigeration, server, space) to reduce inefficient problems.This type of DCSO method is relatively new and has been adopted by some forward-looking IT managers.
Room can be available for monitoring power and cooling equipment data (from DCIM asset management) and server utilization and activities of the telecom room (from ITSM) data.For example, data center managers can use composite data to know the racks that can allocate IT services without affecting the power, cooling, or IT resources of other services.
By linking to DCIM, ITSM, and business systems, DCSO can also improve cost transparency.For example, you can accurately assess a particular service or application in a fairly detailed level costs, such as data center cost allocation to cloud computing service fees, and summarize its electricity bill.This is especially important for cloud providers to ensure that they understand their costs in a competitive environment.The end-to-end cost of IT services is important for private operations or local enterprise data centers to support decisions about whether services should be outsourced.In general, it is influenced by privacy, data governance and other factors.
In addition, you can consider using other business level standard, such as service if you need low latency networks, the infrastructure needed reliability degree, whether can you accept using power management to slow down the application, and whether such as the location of the sensitivity to store data (by region, frame, or even Shared server).
Software driven data center.
The ultimate goal of connecting the DCIM and IT management systems is to extend provisioning automation from IT to the infrastructure layer.For example, this means that IT managers will be able to deploy applications, services, or workloads in the best and least semi-automated way.Consider energy use, cooling availability and availability of resources, such as rack level power (including power redundancy).DCSO method, mission-critical workloads can be dynamically moved to the server, or even the highest power and other refrigeration and the reliability of the data center, such as move the priority work run elsewhere.
Finally, some DCSO platforms are expected to include integration with power companies and micro-grid systems to manage the ac power supply.Data center managers can take advantage of transmission, distribution, cost, supply and use information inside and outside the data center.
In summary, DCSO supports the automated process types that characterize software-driven data centers.If the enterprise does not have operation data center, then there is no need to its application in multiple data centers (internal or external), if there are no plans to run a private cloud, will not promote DCIM, of course also don't have to use DCSO.For other companies, it would be worthwhile to look closely at the technology and its possible evolutionary path.In the next few years, DCIM distributor agreement will become deeper integration and cooperative partnership, and expect its cooperation in the field of IT management vendors began to provide enterprises with a wider range of solutions.
