機房建置,整機櫃服務器市場興起

機房建置,隨着雲計算,大數據應用的普及,數據中心正在走向大型化,如萬今10臺,50萬臺服務器規模的數據中心越來越常見,特別是一些CSP,其數據中心大型化趨勢非常明顯。根據相關統計,以AWS,谷歌,微軟爲首的全球10個超大規模數據中心其服務器部署量佔到了全球服務器保有量的10%,而且這個比值有上升趨勢。

去年,僅AWS一家其服務器採購量就達到了全球服務器銷量的13%。伴隨着服務器採購量的大幅增加,CSP在服務器市場的影響力逐漸提升,(OCP(開放計算項目,Facebook等發起),ODCC(開放數據中心委員會,蝙蝠發起)、工(開放數據中心,LinkedIn發起)等由CSP主導的各種開放計算組織正在數據中心領域的創新中扮演主要推動力。
開放計算受關注
CSP之所以這麼積极參與(OCP和ODCC這些組織,背後的重要原因在於它們在日常的數據中心運維管理中面臨着一些重大的挑戰,爲了應對這些挑戰,它們希望根據自己的需求來對數據中心(包括服務器,存儲,網絡以及空調等)硬件架構進行重新設計,同時也重新設計硬件的採購方式,並簡化數據中心的運維,從而降低採購成本,運維成本和能耗。
其實,CSP面臨的很多挑戰在一些傳統數據中心也存在,只是由於傳統數據中心服務器保有量不大而沒有凸顯出來。而當CSP每天有幾百甚至上千臺服務器需要安裝和部署時,這就成爲一項非常費時費力的工作,同樣,管理數十,數百臺服務器與管理上萬臺,數十萬臺服務器就是一種完全不同的體驗。而如今,每天新上線上千臺服務器,日常管理幾十萬臺服務器在很多CSP(雲服務供應商)中越來越普遍,這樣原本不是問題或者小的問題現在都因爲設備保有量的增加而暴露出來。
爲了應對這些挑戰,CSP們進行了很多創新,如通過重組機櫃內的服務器,網絡和存儲,降低採購成本,同時增加密度,同時,爲了加速創新,也爲了讓這些創新更容易落地,由Facebook等牽頭成立(OCP,去牽頭成立了工,在中國則由蝙蝠等發起天蠍計劃(後來演變爲今天的ODCC)。
“開放計算組織所做的工作主要有三個方向:第一,通過集中供電提升整體效率,第二,提升機櫃的使用率;第三,提高運維效率,降低人力成本。”浪潮服務器產品部副總經理陳彥靈表示。
據介紹,浪潮是ODCC的核心會員,參與多項標準制定,浪潮還是(OCP的鉑金會員和工的首批會員,並且浪潮是目前爲止唯一同時參與上述三大開放計算標準組織的服務器供應商。
“今天,數據中心領域的很多創新很大程度上是由CSP推動的,瞭解了CSP的需求,就把握了數據中心最前沿的需求。”談及浪潮積极參與各種開放計算組織的原因時陳彥靈表示。
當然,站在開放計算組織的角度也需要像浪潮這樣的服務器廠商。畢竟,產品的生產,製造,品質控制以及交付等,服務器廠商更擅長些,藉助浪潮等服務器廠商,可以讓各種開放計算組織的標準更爲可行和完善,也可以協同產業上下游爲這些標準做好配套,縮短標準落地時間。
整機櫃服務器市場興起
頗有意思的,無論是(OCP,ODCC還是工,它們的不少創新都體現在機櫃的整體設計上:一方面,通過集中供電,集中散熱,來減少電源和風扇(或者提高風扇效率)以降低採購成本,另一方面是調整和優化機櫃空間,來提高機櫃的整體裝機密度,節省空間成本。比如,(OCP爲了提升機櫃內的裝機密度,採用了與常規的標準機櫃內寬爲19英寸不同的21英寸內寬,這樣可以並排放置3個6.5英寸的主板和5個3.5英寸的硬盤,通過這一改良將機櫃的空間利用率從73%提升到87.5%。不止如此,爲了最大化各種創新,這些組織都不約而同地提出了各種整機櫃服務器產品設計參考規範。
實際上,伴隨着CSP市場的高速成長,作爲一種可以幫助大型數據中心解決服務器的安裝,部署簡化運維的有效手段,整機櫃服務器正在被越來越多的CSP認可和採用。比如,在中國百度,中國電信和騰訊等都已經部署了天蠍整機櫃產品,這其中浪潮整機櫃服務器因爲高密度,大顆粒一體化交付,集中供電散熱和管理等特點,而成爲整機櫃服務器市場的主要力量。
陳彥靈介紹,浪潮整機櫃服務器有以下幾個突出特點:第,一集中供電,集中散熱,這種集中讓機櫃的供電效率提升了20%左右;第二個是支持高密計算節點,相比通用的服務器其部署密度可以達到兩倍;第三,資源池化。採用SAS開關讓用戶可以通過軟件快速地實現硬盤資源池化,同時還實現了基於作爲PCIe的GPU資源池化。第四,對一體化交付提供了很好的支持。這一點對超大規模數據中心非常關鍵:一方面,和傳統的逐個節點部署,浪潮整機櫃交付能達8 - 10倍速度的提升,另一方面,在運維時可對所有它設備如節點,電源,風扇等統一實現集中監控及擴展,實現了它設備資產信息的自動上報與管理,並優化了系統散熱能耗。
值得一提的是,在和CSP的合作中,浪潮還獨創了JDM模式,即通過與CSP從需求與研發端,採購端,生產端實現全面對接,來共同進行產品創新。陳彥靈就表示,浪潮今天能推出衆多開放計算的服務器節點,JDM模式從中提供了很多幫助。比如,依託JDM模式而誕生的符合天蠍標準的浪潮SR整機櫃服務器已成爲互聯網定製服務器的樣板;浪潮與百度共同推出的SR-AI整機櫃服務器和ABC一體機,更是這種模式的優秀結晶。
據悉,目前浪潮已經與全球全球家CSP中至少5家建立合作關係,正是通過與這些頂級CSP深度合作,推動了浪潮的產品創新的能力與速度,同時也改變了浪潮的傳統發展模式,最終提升了浪潮在市場上的綜合競爭力,也讓志存高遠的浪潮在接下來的全球化市場競爭中走得更穩,更遠。

Website design,What is the principle of search engine optimization?

After the website design, the most important thing is to carry out the SEO optimization of the website. One of the main tasks of the search engine optimization is to improve the search engine friendliness of the web site. Therefore, every link of the search engine has an inevitable connection with the search engine, and the search engine optimization is actually a reverse reasoning for the search engine's work process. Therefore, learning search engines should start with understanding the principles of search engine optimization.

What are the principles of search engine optimization?
1. Grasping information to remove repetition
In the principle of search engine optimization, spiders do a process of eliminating impurities in the database after grabbing information. If your article is caught by a spider and the class is similar to others, the spider will find that your class is worthless and will be easily discarded. There will be many stop words, such as: ",", ",", "ah", "and" and so on.
2, Chinese participle (word segmentation) treatment
Search engines will cut words according to their Dictionary Thesaurus, and divide your headings and contents into many keywords. So website construction companies must include key words in the title and content when creating content.
3, extract the keywords of the website to compare your page content.
If the density of the key words is reasonable, if the density is relatively sparse, the matching degree of your keyword and content is not high, then the key words are generally not good ranking, you can not make the page inside the keyword, leading to the high density, then the search engine will think you cheat, single. Purely want to test the method of ranking keywords to rank, such a method is easy to be punished by search engine.
4. Calculating the link relationship of a page
In search engine optimization, the so-called link relationship between pages refers to the calculation of the export links and import links of your website. The so-called export links refer to links linked to other websites on your website, which are called export links. Import links, more links to import a page, relatively speaking, the higher the score, the better the ranking of web pages. The more links are exported, the lower the score is, which is not conducive to page ranking.
5, elimination of noise treatment
The so-called noise in search engine optimization refers to a lot of pop-up ads on the web page. Unrelated garbage pages. If the web site hangs a lot of pop-up ads Baidu will think that your website has a serious impact on the user experience, Baidu is a severe blow to these sites, not to give you a ranking. Baidu's ice bucket algorithm hits web page ads.
6. Establish an index
The search engine, based on the results of the above, put the web page into its own index library. The content of the index library is actually the result of a good ranking of Baidu. When we use the site instruction to query the website's collection, Baidu releases the contents of the index.
Will you do SEO search engine optimization on the enterprise website?
The content of most of the business websites now is the combination of words, pictures and video. But when the spider engine is grabbed, he can only like the content of the web site and the other is a blank. Therefore, we should study the SEO optimization strategy of enterprise website content according to the preferences of spiders. Only by making sure of this, can we optimize the website. In search engine, the quality of a website depends on whether the content of the website can give users a valuable demand. If you can do that, search engines will give you a good ranking and speed up the number of Web sites. There are also websites to constantly update the content, so that the search engine comes in a fresh sense of time, so the snapshot of the site will be updated in time, and the ranking will slowly go up.

在進行檢查時可對某一火災探測器用專用加煙工具進行實際操作檢查。當火災探測器在接收到煙霧後,報警確認燈亮,表明該探測器工作正常,與此同時向報警控制器發出火災信號。還要檢查時鐘是否走動,有無發生火警的時間記錄。檢查後,值班人員應及時對設備進行消音,復位,以防時間過長而使設備元件被破壞。
2,電源檢查
可檢查火災自動報警系統的交流電源是否因與大型設備電源在一起而引起波動,當發現火災自動報警系統的供電線路與其他用途的照明,動力線路合用同一迴路時,應採取措施分開設置,保證火災自動報警系統單獨迴路供電。檢查火災自動報警系統的電壓偏移是否在允許範圍內,否則應採取調壓措施。世紀星介紹檢查主電源和備用電源間的自動切換是否正常時,可切斷電源,查其能否轉換到備用電源供電,如發現有故障,則應採取措施。電源檢查一般在每季度要對備用電源進行1 - 2次充放電試驗,1 - 3次主電源和備用電源自動切換試驗。
3、觸發裝置在使用中常出現的問題及排除
對於探測裝置因環境條件的改變,而不能適用時,應通過設計,施工部門及時更換。如原客房改爲廚房,鍋爐房,開水房,發電機房時就應將感煙式探測器改爲感溫式探測器。因爲據測定感煙式探測器的環境使用溫度一般在50℃左右,否則有可能出現故障;而定溫探測器動作的額定溫度應要高出環境溫度10℃-35℃。
要防止外部干擾或意外損壞。對於探測器不僅要防止煙、灰塵及類似的氣溶膠,小動物的侵入,水蒸汽凝結,結冰等外部自然因素的影響而產生的誤報,而且還要防止人爲的因素如書架,貯藏架的擺放或設備,隔斷等分隔對探測器和手動報警按鈕的影響,對於進行二次裝修的場,所要注意檢查原探測器和手動報警按鈕等是否完好,可用,線路是否暢通。如有上述問題必須重修或更換,否則報警器就會發生故障報的警。
注意對探測器的清洗和備件的保管。爲了使之保持性能良好,正常運行,應在探測器開啓運行二年後,每隔三年全部清洗一遍。
4,保證聯動控制系統的正常運行
聯動控制系統對保護建築物內安全有着很重要的作用,因此對室內消火栓系統,自動噴水系統,電動防火門,防火捲簾,通風空調、防煙排煙設備及電動防火閥等的控制設備動作要保證運行正常,在檢查時如果聯動系統動作正常,信號就會反饋至消防控制室,若是無有信息反饋,說明設備發生故障,應及時採取措施加以排除。
對滷代烷,二氧化碳,泡沫,乾粉等固定滅火系統,則可通過模擬試驗進行檢查,還應檢查控制中心能否強制消防電梯停於首層,在試驗火災事故廣播時,不論揚聲器處於何種工作狀態,都應能將其切換到火災事故廣播通道上,對所有的火災事故照明燈和疏散指示燈要試驗消防控制設備能否將其接通,並能否正常動作。
檢查所有切換開關如電源轉換開關,滅火轉換開關,防排煙,防火門,防火捲簾等轉換開關,警報轉換開關,應急照明轉換開關等是否動作,對於在檢查中發現的故障,工作人員應及時進行處理,以保證整個系統處於完好的狀態。

Datacenter migration, how to reduce the cost of data center?

Datacenter migration, although organizations have higher requirements for data centers, IT managers do have the means to work within strict budgets.

Today, organizations say their data center budgets are shrinking even as performance expectations continue to improve.While overall IT spending is expected to grow 4.5 per cent in 2018, data centre spending is expected to grow only 0.6 per cent.Forecasts for 2019 actually predict a decline in IT budgets.At the same time, the demand for data center capacity will only grow, especially as new technologies such as the Internet of things, blockchain and artificial intelligence become more and more common in business environments.
The good news here is that most data center operators can cut costs without sacrificing performance if they adopt some policies and measures.The following Outlines four strategies that can reduce budgets and increase output:
(1) smarter maintenance
Leading manufacturers in the industry estimate that data centers lose an average of $9,000 a minute in downtime, which means keeping machines running is critical to maintaining positive ROI.However, according to the manufacturer's recommended maintenance or replacement schedule, users may be harmed in two ways.However, if the replacement time is too long, it may cause downtime due to insufficient performance, which is more expensive than the replacement of equipment.
Solution: use an intelligent tracker to provide active alerts when the device needs attention.For example, real-time monitoring of UPS batteries ensures that staff maintain more reliable data centers while reducing maintenance effort and costs.
(2) consider using equipment with unknown brand
No matter how staff maintain their equipment, it will eventually need to be replaced.The following two specific cost saving strategies need to be considered:
• exceed well-known hardware providers in the industry.By buying products from unknown manufacturers, you can save 30 to 50 percent of your retail costs.Most of these devices are brand agnostic, have the same quality as a well-known brand, and can accommodate any existing infrastructure in a data center.Optical devices, for example, are a technology that can have a significant impact on the speed and function of a data center network.
• understand common markup practices.The Gartner report detailed how enterprise hardware providers sometimes raise the price of fiber optic transceivers by 350%.Users who understand this fact when negotiating overall hardware discounts can save a lot of money.
(3) try virtualization
Virtualization allows staff to optimize low-utilization servers by running virtual instances of the machine, rather than running only one application per server.The potential benefits are significant: you can run more applications while reducing the amount of hardware you have to maintain.Estimates from 2008 show that data centers can reduce overall costs by up to 40% through virtualization.
It is important to note that the transition to a virtualized or semi-virtualized environment requires careful review of the data center configuration.Some servers are not suitable for virtualization (for example, if there are regulatory or security restrictions).With virtualization, it takes time to compose the server logically.Energy star also provides some key guidelines on how to think about this transition and how to save energy for users.
(4) improve employee retention
According to the survey, the cost of employee turnover is between 16 percent and 213 percent of annual salary.The cost increases with staff education and experience.IT is important to remember that the data center's IT staff is at the top of this range, remembering that business leaders want to cut wages to control costs.
In some cases, the cost of alerting a leader to valuable employee departures may help prevent them from leaving.
Common docking of BYOD workplace
Bandwidth constraints make wi-fi itself insufficient to meet the needs of BYOD workplaces.That's why DisplayLink has introduced a universal USB interface that meets the rigors of the popular office and other emerging digital workplace models.DisplayLink marketing director Andrew Davis also demonstrated its new wireless VR headset connectivity solution.
Often, many companies don't even understand that their team members are looking for other jobs.Even if it doesn't offer the highest salary or the best benefits (the technology competition is fierce), companies can create a pleasant environment and culture.
The following work can improve the retention rate, which can significantly save the cost of the data center:
• provide opportunities for development and development.This can be anything that supports additional learning and training for employees to pay part of the tuition or to employ a new skill training team.Find the skills they want to learn and help them achieve their goals, and they have better reasons to stick with them.
• competitive compensation.Companies need to compensate their teams as much as they can.Paying too little can breed resentment and increase employee turnover.
• provide the benefits the team wants.Whether it's flexibility at work, good health care, lunch or anything else, you need to understand what the team wants and work with the leadership to implement it.
• avoid micromanagement.This will force employees to consider leaving.
• check and communicate.Don't wait until the exit interview to see what went wrong.Check daily work regularly to find out how satisfied employees are with the company.If they want change, they need to be honest about what the business is doing.
Management: let business managers know about the cost of downtime
Cost reduction in data centers is a achievable goal.When you see the need to pay for new hardware or hire team members, be prepared to communicate the value of your data center to your business leadership.
Knowing the loss of $9, 000 per minute of downtime could scare even the most budget-conscious chief executive.Remember that data centers are not costs, but investments.Showing how leadership provides the right funding for a business is the only way to achieve larger business goals and is the key to the business's needs (though it may not cost a cent more).

機房建置,佈線系統運維和管理

機房建置，隨着近年來金融業的高速發展,其對信息存儲和處理能力的要求越來越高。金融業的各種服務都依賴於對信息的管理和分析。數據中心作爲支持信息化應用的平臺,將扮演越來越重要的角色。許多用戶不惜重金建設新的數據中心,數據中心的規模和規格都不斷擴大和提高。這對數據中心的管理就提出了更高的要求。佈線系統,作爲數據中心網絡運行的基礎,也是數據中心繫統一個重要的組成部分。如何能夠更好的管理數據中心的佈線系統,現在也越來越受到關注。

數據中心佈線系統的良好管理首先從就要求從整體架構上採用諸如結構化佈線的設計思想,還需要給升級和擴容留出足夠的空間和佈線的能力,從產品上,要求能從使用角度出發,採用更貼近實際使用方,更易於管理和維護的產品,最後還能採用一些輔助手段,如電子配線架、電子化標籤管理系統等手段,來幫助管理數據中心的佈線系統。良好的佈線管理能夠有效地減少維護的時間,降低發生錯誤的可能性,同時也能夠通過減少對冷風通道的影響,提高數據中心的能源使用效率。我們通過對多個數據中心長時間運營的調查發現,良好的佈線管理能夠降低2% - -3%的能耗。下面就以某保險總部數據中心爲例,介紹如何能更好的管理和維護數據中心的佈線系統。
方案設計可以說是對管理影響最重要的部分,只有良好的設計採用使維護變得簡單和方便。在TIA942,ISO24764,GB50174等標準的引導下。結構化佈線已經被大多數數據中心所採用,根據統計,在歐洲,目前大約有95%以上採用的是結構化佈線的方案。
過去數據中心佈線系統多采用直連跳線的連接方式。從一個設備的端口到另一個設備的端口多采用一根雙工光或者銅跳線直接連接,這樣對於初期投資小,而且無需規劃。乍看之下是比較經濟而且有效的選擇,但是隨着設備數量和端口數量的快速增長,就必須在現有的佈線基礎上不斷的在地板下或者架空橋架上不斷的增加設備間直連的跳線。很快,所有的可用空間都會被跳線所佔據了。用不了多久,就無法確定的找到相應跳線的對應關係了。所以直連跳線這種方式,雖然在初期看尚比較有效,但是在後期維護和擴容的時候就變得非常複雜,麻煩而且伴隨着較高的風險。因爲直連方式只有跳線兩端是已知的,而中間的確切線路是很難查找的,地板下的跳線通常會變成一團糟。而當系統的連接需要變化時,還需要打開設備機櫃,插拔有源設備上的連接器,這樣可能會危及到其他的連接和系統的運行,可能帶來的風險是不可預測的。
混亂的佈線
數據中心應用需求增長的不確定性給數據中心的升級和管理帶來的很大的麻煩,每天數據中心管理人員都面臨着諸如硬件技術更新換代和軟件系統升級等多種不斷變化的情況。他們必須考慮如何在增加新的應用的時候,還能夠減少系統的複雜性。特別是在金融行業,系統升級的窗口時間非常短。如果像過去那樣,採用直連跳線方式,如何在一堆線纜中找到我們想要的那一根就變成管理人員最爲頭疼的事情。很多寶貴的時間都浪費在如何去找到跳線的對應關係上。這是讓人無法接受的。另爲因爲尋找線纜所花費的時間無法較準確的估計,安排長時間的系統升級窗口也是一個非常麻煩的問題,太短有可能無法在規定時間內完成切換,太長了又有可能會對業務造成影響。
如何才能避免這種混亂的狀況?答案是採用結構化的佈線系統,加上良好的標籤標識系統,以及完善的文檔管理。結構化的數據中心佈線通過在線纜兩端的配線架,建立起一個通道,通過這個通道,我們將設備上的端口映射到集中配線和管理區域。這樣對佈線系統的維護,管理和升級就可以被隔離在集中區域之內。再配合良好定義的標籤和管理文檔。這樣維護的時候我們再也不需要去尋找通道當中的線纜,只需要在配線架面板上找到相應的端口就可以了。這樣大大簡化了佈線的管理,節約了大量的時間。
數據中心的結構化佈線
結構化佈線和跳線直連方式之間的差異就是對於佈線管理能力的區別。通過結構化佈線,如果新增設備,從新增加的設備到主配線區的佈線系統是可以在正常工作時間內完成,無需安排時間窗口。只需要安排較少的時間窗口,就可以完成主配線區內的跳線安裝工作。可以大量節約系統升級和割接的時間。如果要變更系統的連接,只需要在主配線區更換跳線的端口就可以了。這意味着管理更簡單,更快捷了,顯著的降低了風險,提高了系統的整體響應速度。
另外數據中心規劃的時候,還需要對將來擴容的能力留出足夠的空間。特別是在主配線區域,如果主配線區域在初期就被安排得很滿,那將來擴容設備的結構化佈線系統就無法添加進取,這對升級,擴容和管理都帶來了很大的麻煩,所以在規劃之初就需要對數據中心的主配線區有一個很好的設計,即要滿足現在的使用,也需要給將來的升級留足空間。

Datacenter migration，network details determine quality

Datacenter migration, the network is an important part in the data center, network is a system, by the different functions of network equipment, optical fiber link, optical module, power components, such as through the network to connect all the computing devices in the data center, but also realize the data center of the internal and external data access requirements.A data center network evaluation standard of good and bad, there are a lot of aspects, failure rate, etc., delay and bandwidth, the homogeneity competition in data center, technology mature, as long as the funds in place, these are not problems, so it is particularly important to many of the details, and is no longer just to compete, so some of the prestige projects.In this paper, the design details of some network equipment are introduced, which can make the network system of data center a focus and improve the network quality of data center in an instant.

Port caps should not be missing
We know the network equipment, of course, is to include a lot of port, the port to implement the interconnection of many equipment, many high-end equipment will be how much the port number of the machine as a competitive index, a large number of ports will not use all at the beginning, and a lot of equipment is not all forward speed, nor will all ports to use.
These unused ports need to be fitted with port caps in time to block the empty ports.Some network devices in order to reduce costs, does not provide a port cap, actually is wrong, so bad instead to the service life of equipment, cost more than a dozen pieces of port cap can greatly enhance the service life of equipment.
Why do you say that?Data center computer room environment, while relatively closed, but it is not dust-free environment, network equipment, if the panel is suction mouth way, keep the air suction equipment, ventilation, such as the air into the equipment in addition to the dust, and there may be some impurities and foreign bodies, if these things are coming into the port, may accumulate constantly, when to use this port is likely to damage caused by a foreign port.Practice has shown that fifty percent of the port problems related to foreign body into a has 48 port equipment cannot be used as a port, to change the whole machine is very not worth it, increase the port cap can avoid these problems.At the same time, the port on the cap also can block a lot of dust into the equipment, so it can avoid too much dust inside the equipment, static electricity, such as short circuit fault occur, good for the equipment and stable operation.
Paper labels are necessary
In order to reduce the cost, many devices do not provide the function of electronic label, so that it is impossible to know the model and code of each component of the equipment, which is not convenient for statistics and maintenance.It is important to have paper labels on the parts of the equipment when they are vulnerable to damage or when the parts are running on the equipment and cannot be removed for inspection at all.
Influential position these labels on the outside of the parts, or as some equipment directly design the small slot, dedicated to insert the electronic label paper card, as long as will come out paper card can view, although there is no electronic tag view, also is better than not, after all the tags not all equipment parts to support (or to increase the storage device, increase the cost).In addition to marking bar codes for equipment parts, you can also mark the role of equipment in the machine room, interconnect optical fiber, etc. These labels are very useful when replacing faulty parts or equipment.
Dust nets have a great effect
Today's equipment USES a dust screen as an optional component, and a decade ago it was part of the equipment.Dust-proof net effect is self-evident, is to prevent dust or foreign body into the device, is a large number of components and circuits inside the equipment, if long time in a dusty environment, affect the service life, and the equipment cannot be washed, such a dust-proof net is different, can regularly to cleaning of dust-proof net, effectively reduce dust to enter.
Anti-dust mesh as optional parts, of course, there is a reason, now the data center environment are standard rooms, the environment is relatively clean, itself very little dust, dust into the equipment a little simply nothing, and the design of the power supply before head is larger, the power is must add dust-proof net, to prevent the dust into the influence of too much power, power is more important on the entire network equipment is more vulnerable parts, now is different, the power volume is small, with no dust on the net.Still have, dustproof net still affects equipment heat dissipation very much, dustproof net with better dustproof effect is bigger to heat dissipation influence, dustproof net is a double-edged sword.Therefore, the choice is given to the user. The client should make the choice according to the situation of his own data center.
Usually if room environment is good, need not install, if the room environment is bad, need to install, disassembly and cleaning on a regular basis, computer room environment is not good to pay attention to ventilation, to ensure that increase the dust-proof net, equipment internal temperature not too high, do not reach the minimum threshold.
The wire rack is beautiful
Network equipment frame network equipment, in particular, have higher port density, high some have hundreds of ports, so many ports on optical fiber, cable, it is of all is the line, if this does not do, can appear very messy around the entire device.A wire frame is not the same, Richard wire frame is designed according to the characteristics of equipments, articulated on the outside of the equipment, port on optical fiber into the port after, can get reasonable line on the shelf, so each of the optical fiber can be completed.The stringing frame is actually made up of a number of horizontal pipes. The whole equipment will look neat and orderly when the fibers going to different directions are laid on the horizontal pipes.This is not only clean and beautiful, when changing the port or board card, it is also not wrong to change, causing human fault, so the cable management frame can not only be beautiful, but also reduce the occurrence of fault.
In addition to the above, there are also light module clips, convenient to plug modules;Grounding wire of equipment to prevent static electricity;Device electronic digital tube, display some important information and so on, the design on these details often can reflect the quality of a network more.A person's quality is not high, often from his behavior can be observed on the detail, the same can be said of network if even in good condition, so the details on the design, that the network quality is bad.As the saying goes, "the details determine the success or failure". It is true that every detail on the data center network ultimately determines the quality.Therefore, to evaluate the good and bad of a data center network, we should pay attention to the design of details, which can often reflect the real level of the network.

What are the aftersales of professional website design services?

Website design, with the rapid development of the network, now many enterprises have been transferred from the line to the line, so this time will not build one of their own enterprise website, can show what the enterprise want on the website, so that users better understand the enterprise. The website design is just the beginning of the Internet application. A lot of work to gain real benefits is in the following aspects: website promotion, network marketing and training of network application knowledge for customers. Therefore, after the completion of the website design, there is also a need for a perfect after-sale service system. Today, we will explain systematically what aspects of after-sales service of professional website design services include.

First, domain name maintenance
The domain name in the professional website design service is rarely a problem, but it does not exclude the possibility of the problem, so it is necessary to say that the domain name maintenance is necessary. The domain name maintenance mainly refers to the timely provision of standby solutions when the domain name is registered, so that the site can be accessed temporarily, and the after-sale service should be solved as soon as possible. Domain name failure, restore the normal use and access of the domain name.
Two. Space maintenance
The space maintenance of the professional website design service is the focal point of the website after sale service. At present, no Internet Co provides space services without any problems in one year. It is recognized that the network has a certain instability. Besides the hacker attacks, such as the network circuit fault of the telecommunication machine room and the soft computer system. Part failure, computer hardware and so on, there are also some policy reasons, such as before 2009, the site is not put on record is completely voluntary, do not affect any use. But in the second half of 2009, the national Internet Information Management Center (CNNIC) suddenly hit unrecorded websites, and the domestic sites were closed everywhere. First, small business websites were not said, and large websites were forced to shut down.
And, from the end of 2009 to the present, the national record policy is constantly changing, at first it must be submitted, and then it must be developed to the express company's business license or the person in charge, and then to the telephone review. If the record information is not true or even the telephone can't be dialed, I am sorry for the record. The website is closed, and documents are issued in some areas. Many uncontrollable factors, making the website less likely 365 days a day normal, then the site is closed, there is no way to let the site "escape"? The answer is. The solution is as follows:
If your website is.COM/.NET/ORG and other domain names, you can buy foreign website space, put the website data on the foreign website space, the website can be visited normally; then there is a timely solution to the problem of domain name filing (site space filing); find the reasons for the cancellation of the record, the first time solution. By the way.
Method two, if you are not the domain name is.CN domain name, may not be able to use method 1 to solve, and sometimes the CN domain name is canceled, the domain name may not continue to use (some can also be normally parsed). This can only buy new domain names, buy new foreign website space, and then solve it according to method 1.
Three. The maintenance of the website system
In the after-sale service of professional website design service, the maintenance of the website system is mainly how to restore to the normal state when the website is misoperated (such as mistaken delete); and some places may be modified locally with the development of the enterprise. The different website construction companies have different service standards, most of the situation Under the circumstances, our company serves the customers free of charge.

機房建置，如何解决传统硬件故障的挑战？

機房建置， 對於今天的企業組織機構而言,仍然在堅持使用傳統系統的一大主要原因便是:這些企業有相當一部分的關鍵型任務工作負載仍然還在哲學傳統系統上運行,而採用此方案對於這些企業組織而言是有利的。但是,儘管有這些傳統遺留系統的功能對於它企業組織機構而言意義重大,但一大不容忽視的現實問題則是:這些傳統遺留系統正在迅速老化。這也就意味着它們可能會逐漸變得不那麼可靠,並且更容易出現故障。而一旦這些傳統系統硬件設備出現故障運行失敗時,其所帶給企業組織的影響可能是毀滅性的。而在本文中,我們就將幫助廣大讀者朋友們詳細瞭解如何制定虛擬化計劃,以便能夠主動的防止系統故障所帶來的破壞性結果,並進一步的幫助貴公司節省更多寶貴的資源。當涉及到它企業組織機構的傳統遺留系統時,可以說存在着很多的變數:這包括您企業數據中心所使用的硬件設施,運行在其之上的傳統操作系統以及運行在其上的應用程序。您企業將仍然繼續維護這些傳統遺留系統的原因就在於,這些傳統系統對您企業的業務至關重要。這可能是關鍵型的任務,有助於讓你輕易的員工順利完成業務目標。的確,企業的傳統遺留系統涉及到存在着很多的變數。但所有的這些傳統遺留系統都至少有一個共同點,而這一共同點無疑又是非常重要的(甚至是最爲重要的因素),即:這些傳統遺留系統正在迅速的老化。隨着企業組織的這些傳統系統的逐漸老化,它們將變得不太可靠,而且,硬件的使用壽命是有限的,但在其之上運行的軟件和應用程序的壽命則往往要長得多,通常是底層硬件使用壽命的三到五倍。您企業可能已經遇到硬件故障或對硬件支持的需求增加的難題了。您甚至可能已經在搜索更換相關部件的方案或開始調查相應的替代品了。而如果你企業目前尚未遇到傳統硬件方面的困難,那麼我們建議您需要意識到這只是一個時間的問題。對於那些已經意識到上述硬件故障的出現只是一個時間問題的企業組織來說,這意味着他們至少現在還有時間來採取積極的應對措施,他們可以將相關項目的重要性降低,以支持那些更加緊迫的項目。但我們卻遇到過很多企業都分別表達了類似的敷衍觀點:“硬件故障對我們來說目前還不構成問題,我們稍後可能會有相應的跟進措施。”而現實情況則是,一旦傳統硬件出現故障,這些企業往往會後悔爲什麼沒有提前進行規劃,一旦傳統硬件出現故障時,就再也沒有後悔藥了:屆時,讓系統重新運行起來的將變得非常緊迫,這對企業業務的成敗至關重要。那麼爲什麼當前仍有這麼多的企業對於潛在的問題如此敷衍呢?爲什麼企業在其會影響到企業營收甚至還將承擔相應責任時仍然沒有爲其傳統舊系統提前制定相應計劃呢?在本文中,我們將與您一起探討當前企業遲遲拖延,未對其傳統遺留系統採取保護措施的最常見的原因,並介紹爲什麼提前制定計劃是最好的應對方式。文章將深入討論延遲實施這些計劃所將帶來的相關的成本以及他們如何定期影響到企業業務。最後,我們與您分享關於企業如何制定定製化的計劃方案,以確保您的傳統遺留系統成爲商業機會的來源,並提高投資回報率,而不是您企業的“定時炸彈”的最佳實踐方案。爲什麼企業會延遲實施針對傳統系統的應對措施儘管存在與硬件故障相關的風險,但仍有許多企業組織遲遲沒有對其傳統遺留系統採取下一步的應對措施。究其原因何在呢?1、預算成本問題通常是最大的障礙。由於企業的它預算有限,導致獲得進一步投資於傳統遺留系統的批准可能很困難。企業通常很少或根本沒有爲這些後備系統分配資金,因此,讓我們面對現實吧,這些傳統遺留系統已然不是企業會承諾提供無條件支持的最具魅力的項目。2,優先原則企業在保持緊跟最新技術領域發展潮流的挑戰之下,會使得其對於傳統遺留系統的維護傾向於落後。傳統遺留系統不是新潮技術,並不新鮮,但這些傳統遺留系統所執行的往往是企業的關鍵任務,因此,企業在工作中往往會秉承着“如果沒有壞掉,不要這樣修理”的心態。只要其傳統遺留系統能夠繼續維持運行,那麼其他領域的就會被優先考慮。

企業爲什麼不能拖延實施針對傳統系統的應對措施
企業延遲實施針對傳統系統的應對措施最終是要付出代價的。在許多情況下,拖延的損失往往大於投資於長期解決方案的成本。如下,是你企業爲什麼不能拖延的原因分析:
1,該系統非常關鍵
當進行原因歸結時,往往是因爲您的企業需要這個系統。其對於您企業的運營和業務的成功至關重要。一旦系統出現故障,您將遇到麻煩。以醫療保健行業爲例,其傳統系統難以維護病人的記錄。如果醫院在發生硬件故障時丟失了這些病人記錄,醫院將違反HIPAA法律規定,並需要承擔重大後果,包括相關法律責任。而如果是其傳統系統的故障導致公用服務機構或金融服務企業無法訪問他們多年的數據記錄的話,那麼他們將遭受鉅額的罰款。
2、成本損失加大
拖延的成本會很高企。業如果被發現違反行業規定,除了可能受到監管法律的處罰或訴訟的風險外,還有備用零件的成本,更不用說還會涉及到一些額外的成本,有時候某些備用零件的性能不如原件那樣奏效。在包括政府和金融在內的一些行業,80 - 90%的預算致力於維護傳統硬件。除了備用零件外,還有對這些傳統硬件的支持成本,隨着這些傳統老舊系統的專家逐漸退休或離開企業員工隊伍,對於這些傳統硬件的支持成本會不斷上漲,最後,當傳統硬件一旦出現故障時,還將涉及到停機中斷的實際成本損失。例如,在製造業中,停機成本可能是一天或更多天的生產價值。
以美國的珠寶製造商Wheeler製造業爲例。當他們的傳統硬件出現故障時,他們需要等待支持人員到達位於中西部農村的工廠,他們因此就會損失數天的生產時間,根據製造工廠的規模或工作類型的不同,一天時間的停機可能意味着損失高達數十萬美元。正是由於遭受過這種慘痛的生產時間浪費的經歷,該珠寶製造商纔開始投資於相應服務供應商的服務器解決方案。而藉助這些解決方案的部署,使得該珠寶製造商擁有了安全性,其生產將不再受到傳統硬件故障的影響。
企業拖延實施針對傳統系統的應對措施的成本
拖延對傳統硬件進行虛擬化的成本將會非常高昂,並且這會涉及到許多的組件和變量,具體則取決於您企業的業務情況以及對於傳統系統的使用方式。如下,我們將爲您重點介紹拖延會導致的關鍵成本損失。
1、停機損失成本
那麼宕機成本是多少嗎?很明顯,其會因企業的不同而異,但如下有一些相關的數據,根據Gartner的一項調研顯示,企業組織每年可能面臨大約87小時的系統停機時間。他們估計這一宕機時間的小時成本爲42000美元,這意味着這些大公司每年所遭受的損失總額將超過360年萬美元。而其他相關消息來源則提出企業平均每小時的停機中斷成本高達每小時84000到108000美元。根據《今日美國》的一項調查詢問了200位的數據中心經理有關停機時間的問題,80%的受訪者表示每小時的成本超過5萬美元。25%的受訪者表示他們所在企業每小時的停機成本超過50萬美元。
而來自Forrester的一份報告表明,硬件故障佔計劃外停機時間的31%,而著名的商業信息服務機構Dun & Bradstreet則認爲,財富500年強企業中,有59%的企業每週至少會發生1.6小時的停機時間。有一份報告更進一步計算了發生停機中斷時間對於勞動力成本的影響,假設每名員工都受到停機中斷的影響,那麼單就企業勞動力方面而言,每週的成本損失就會超過80年萬美元,每年總計超過4600年萬美元。
儘管許多並不位列“財富”500年強企業名單上的企業組織所遭受的損失可能較小,但貴公司又可以承受多長的停機時間呢?這是一個重要的問題,特別是當這種停機中斷原本是可以預防的時候。
2,遷移成本
由於宕機成本可能會達到天文數字的級別,因此企業拖延實施針對傳統系統的應對措施還會產生其他方面的成本。遷移到全新的平臺當然可能非常昂貴。創建一款新的應用程序是需要成本開銷的;這還包括員工再培訓的成本,將來自傳統平臺的數據遷移,轉換到新的平臺;以及在遷移過程中丟失數據可能產生的成本。所有這些成本都會因行業而不同,並且在垂直方向上,其會因具體公司的不同而異。
根據Softek公佈的針對數據遷移相關的隱藏成本所進行的調查顯示,83%的企業在遷移過程中會遇到問題,其中意外停機成爲主要問題。其他問題包括技術兼容性問題,數據損壞,應用程序性能問題和數據丟失。此外,布盧爾研究在2011年進行的研究表明,企業的數據遷移項目經常會超出時間和預算限制。數據遷移項目的平均預算爲875000美元,但這類項目中只有62%是“按時按預算“投入的。
3維護成本
最後,還有與維護相關的成本費用。即使您企業的系統保持正常運行,或者即使您企業暫時不考慮遷移問題,但傳統系統每年會爲您的企業組織帶來哪些相應的影響呢?隨着傳統硬件老化並達到使用壽命的終點,相應的支持維護將變得不太容易獲得。許多傳統硬件的專家們正在從勞動力隊伍中退出,或者進入更新的技術領域。而伴隨着可用支持技術人員數量的減少,維護這些傳統平臺的成本也在上升,你企業願意爲支持這些舊系統付多少錢?更重要的是,您企業是否可以以更少的成本,讓相關的應用程序比以前更可靠地運行嗎?
許多公司每年支付高達50000美元的費用來支持單一的傳統遺留系統的維護。如果你企業能在一年內減少50%的維護支持費用,並在此後每年減少95%呢?如果您企業運行的是多款傳統遺留系統,請想象一下由此可以節約出多少的預算以供給其他部門。而藉助使用傳統硬件虛擬化技術,這是可能實現的。
制定計劃
如果你企業有一套傳統遺留系統,正面臨相關硬件老化並有發生故障失敗的危險。同時對相應部件的更換更難以實現,並且隨着企業內的傳統硬件專家們逐漸退休,企業內部對於這些傳統系統的知識的掌握正在減少。有鑑於此,提前爲您企業的這些系統制定相關的戰略是至關重要的。爲了制定計劃,企業首先需要評估他們的選擇:
1、選擇一:維護老化的硬件
如上所述,這通常意味着到eBay網上或其他零件經銷商處尋求使用過的零部件。這意味着要在故障發生之前提前採購,並在發生故障時做好準備,儘快訂購備件。對於停機時間較短的企業或只將其系統用於存檔功能的企業而言,此選項通常最爲可接受。
2,選擇B:遷移軟件
雖然這一選擇方案通常有效,但其是成本昂貴且耗時的。遷移需要耗時幾個月(即時不是幾年的話),可能需要部分或全部重寫應用程序。此外,還需要對員工再培訓,讓每名員工都能夠在新系統上加快速度操作。遷移本身也可能是有風險的:數據遷移伴隨着一些信息可能在此過程中丟失的現實。所涉及的時間,成本和風險可能會使此選項無法奏效。除了這些因素之外,遷移還會導致對於“硬件可能發生故障,但應用程序本身仍然運行得很好”這一事實的忽視。
在沒有硬件仿真的知識的情況下,大多數公司都會考慮上述兩種選擇中的一種,或者兩種選擇的組合:在遷移之前儘可能長時間的維護系統。在方案一個和方案B之間所進行的選擇,往往使得企業最後發現自己處於困境之中。
3、選擇C:硬件仿真
藉助市場上相關服務供應商的傳統服務器仿真功能產品,您企業可以更輕鬆,更經濟高效地完成相關的工作。選擇C虛擬化了傳統硬件,允許傳統應用程序在行業標準服務器上運行,無需修改。選一項的難題被消除了:因爲這些解決方案運行在現代工業標準硬件上,所以不需要爲傳統硬件尋找備件。而與選擇B不同,選擇C成本低,風險低,執行過程相對較短(幾天之內,通常不到一週)——這意味着企業可以保持其仍然可靠的應用程序的完整性。
此外,這些解決方案供應商的技術專家團隊在傳統遺留硬件,應用程序和操作系統方面擁有豐富的經驗。通過與這些專家們一起討論您企業的目標和性能驗收標準,並對您的系統進行盤點,專家將幫助分析你企業的操作運營環境,以確定最好的產品和主機系統。
下一步是安裝。這些解決方案的供應商將在符合您企業所屬行業的標準服務器或您選擇的公共雲服務中安裝這些方案,然後恢復傳統遺留系統的完整備份。在大多數情況下,這是一個您企業環境中完全測試您的應用程序的機會。如果存在任何行爲差異,則在此階段應該對其進行分析和消除。在功能和性能測試成功完成後,將繼續進行流程的最後一步:數據遷移。當然,這與軟件遷移明顯不同,因爲您企業的應用程序在這一過程中未被修改,這類解決方案允許您企業的未更改應用程序在新的平臺上運行,就像它們在原始硬件上運行一樣。您的系統仍然能夠獲得維護支持。安裝後,供應商的支持團隊即可進行診斷,故障排除和一般維護。
藉助這些系統遷移計劃,你企業的痛點能夠得到有效解決。您可信的傳統遺留應用程序就能夠像以往一樣運行,而員工們也不需要再培訓,您的團隊也不會擔心停機中斷,並能夠確保業務的連續性。
總結
企業的傳統遺留系統太重要,但鑑於某些企業無法對其實施更好的保護,我們建議企業客戶選擇市場上相應的解決方案和專業知識來幫助您企業避免與傳統遺留系統相關的這災難。儘早的未雨綢繆。藉助這些解決方案的部署,企業客戶可以確保其關鍵任務應用程序的運行,消除風險,降低成本並避免預算超支,快速提高其硬件系統的投資回報率。投資於確保未來能夠持續運行的傳統遺留系統是企業實現持續成功的關鍵。

Datacenter migration network details determine quality.

Datacenter migration, the network is an important part in the data center, network is a system, by the different functions of network equipment, optical fiber link, optical module, power components, such as through the network to connect all the computing devices in the data center, but also realize the data center of the internal and external data access requirements.A data center network evaluation standard of good and bad, there are a lot of aspects, failure rate, etc., delay and bandwidth, the homogeneity competition in data center, technology mature, as long as the funds in place, these are not problems, so it is particularly important to many of the details, and is no longer just to compete, so some of the prestige projects.In this paper, the design details of some network equipment are introduced, which can make the network system of data center a focus and improve the network quality of data center in an instant.

Port caps should not be missing
We know the network equipment, of course, is to include a lot of port, the port to implement the interconnection of many equipment, many high-end equipment will be how much the port number of the machine as a competitive index, a large number of ports will not use all at the beginning, and a lot of equipment is not all forward speed, nor will all ports to use.
These unused ports need to be fitted with port caps in time to block the empty ports.Some network devices in order to reduce costs, does not provide a port cap, actually is wrong, so bad instead to the service life of equipment, cost more than a dozen pieces of port cap can greatly enhance the service life of equipment.
Why do you say that?Data center computer room environment, while relatively closed, but it is not dust-free environment, network equipment, if the panel is suction mouth way, keep the air suction equipment, ventilation, such as the air into the equipment in addition to the dust, and there may be some impurities and foreign bodies, if these things are coming into the port, may accumulate constantly, when to use this port is likely to damage caused by a foreign port.Practice has shown that fifty percent of the port problems related to foreign body into a has 48 port equipment cannot be used as a port, to change the whole machine is very not worth it, increase the port cap can avoid these problems.At the same time, the port on the cap also can block a lot of dust into the equipment, so it can avoid too much dust inside the equipment, static electricity, such as short circuit fault occur, good for the equipment and stable operation.
Paper labels are necessary
In order to reduce the cost, many devices do not provide the function of electronic label, so that it is impossible to know the model and code of each component of the equipment, which is not convenient for statistics and maintenance.It is important to have paper labels on the parts of the equipment when they are vulnerable to damage or when the parts are running on the equipment and cannot be removed for inspection at all.
Influential position these labels on the outside of the parts, or as some equipment directly design the small slot, dedicated to insert the electronic label paper card, as long as will come out paper card can view, although there is no electronic tag view, also is better than not, after all the tags not all equipment parts to support (or to increase the storage device, increase the cost).In addition to marking bar codes for equipment parts, you can also mark the role of equipment in the machine room, interconnect optical fiber, etc. These labels are very useful when replacing faulty parts or equipment.
Dust nets have a great effect
Today's equipment USES a dust screen as an optional component, and a decade ago it was part of the equipment.Dust-proof net effect is self-evident, is to prevent dust or foreign body into the device, is a large number of components and circuits inside the equipment, if long time in a dusty environment, affect the service life, and the equipment cannot be washed, such a dust-proof net is different, can regularly to cleaning of dust-proof net, effectively reduce dust to enter.
Anti-dust mesh as optional parts, of course, there is a reason, now the data center environment are standard rooms, the environment is relatively clean, itself very little dust, dust into the equipment a little simply nothing, and the design of the power supply before head is larger, the power is must add dust-proof net, to prevent the dust into the influence of too much power, power is more important on the entire network equipment is more vulnerable parts, now is different, the power volume is small, with no dust on the net.Still have, dustproof net still affects equipment heat dissipation very much, dustproof net with better dustproof effect is bigger to heat dissipation influence, dustproof net is a double-edged sword.Therefore, the choice is given to the user. The client should make the choice according to the situation of his own data center.
Usually if room environment is good, need not install, if the room environment is bad, need to install, disassembly and cleaning on a regular basis, computer room environment is not good to pay attention to ventilation, to ensure that increase the dust-proof net, equipment internal temperature not too high, do not reach the minimum threshold.
The wire rack is beautiful
Network equipment frame network equipment, in particular, have higher port density, high some have hundreds of ports, so many ports on optical fiber, cable, it is of all is the line, if this does not do, can appear very messy around the entire device.A wire frame is not the same, Richard wire frame is designed according to the characteristics of equipments, articulated on the outside of the equipment, port on optical fiber into the port after, can get reasonable line on the shelf, so each of the optical fiber can be completed.The stringing frame is actually made up of a number of horizontal pipes. The whole equipment will look neat and orderly when the fibers going to different directions are laid on the horizontal pipes.This is not only clean and beautiful, when changing the port or board card, it is also not wrong to change, causing human fault, so the cable management frame can not only be beautiful, but also reduce the occurrence of fault.
In addition to the above, there are also light module clips, convenient to plug modules;Grounding wire of equipment to prevent static electricity;Device electronic digital tube, display some important information and so on, the design on these details often can reflect the quality of a network more.A person's quality is not high, often from his behavior can be observed on the detail, the same can be said of network if even in good condition, so the details on the design, that the network quality is bad.As the saying goes, "the details determine the success or failure". It is true that every detail on the data center network ultimately determines the quality.Therefore, to evaluate the good and bad of a data center network, we should pay attention to the design of details, which can often reflect the real level of the network.

Enterprise display type the skills of Website Design

Enterprise display type website design has always been a very important brand publicity and product promotion channel for enterprises. The exhibition enterprise website is also the preferred type of Web site for some design companies or companies that focus on product display, such as enterprise, institution, school, hospital, organization and so on. The purpose of this kind of enterprise is to build a website. Mostly for the purpose of displaying the image of an enterprise or unit, introducing its services and products, and providing users with detailed contact information. So what are the skills of making and designing an exhibition website?

First, clearly display enterprise website design theme
The main purpose of the design of the enterprise display type website is to promote the purpose of the enterprise through the display of the information of the enterprise itself, its products and services and so on, thus enhancing the reputation or exposure rate of the enterprise, and bringing more customers to the enterprise.
In designing the design of the display type website, we need to personalize the design according to the content you want to display, and show the user with emphasis, simple and elegant, beautiful and practical image, so that users can find the information that they need quickly and quickly, improve the click rate of the website, and get more traffic.
Two, setting up the design framework of the display type enterprise website
The design of the web site's navigation, column, title and other information should be optimized, using SEO and search engine knowledge to set up the internal framework of the website so that the enterprise website can quickly adapt to the needs of operation and promotion.
The main function of the display enterprise website is to spread the information of the enterprise to the user, so the design framework needs to be designed around the content to be displayed, and the same is the practicability and artistry of the website. Generally, the exhibition and design are mainly based on pictures and animation.
Three, highlight the personalized design of exhibition enterprise website.
The design of the design of the enterprise display website is easier than the e-commerce website and the portal type site. It can lead to the rational design and use of color and pictures, and make the website stand out in many peer websites. This is a must for the display enterprise website designer, because only in this way can we attract users to click on the reading website.
Website design color matching skills:
1, the entire website color should be unified, as far as possible with a color, can adjust the color of the transparency or saturation, produce gradual color, so that the page looks like a uniform color, there is a sense of hierarchy.
2. if you need to use two colors, you need to select a color first, then choose the contrast color to add one color.
3. choose to use a color system. The colors in the website should give people the same feeling. Such as light blue, light yellow, light green, or yellowish, gray, blue.
Four. The style grasp of the website design of the display type enterprise
The design style of the website has always been a problem that all types of website design must be solved. It embodies the image of the enterprise and the website. It is an invisible language. The user can like your website and understand your product because of the design style of your website. Display enterprise website design must reflect its own style characteristics.
The style of the website design of the display type enterprise should be based on the theme of the website and the characteristics of the enterprise products. Through artistic sublimation and design, the style of web design with both aesthetic and practical features is obtained. The main contents of the design style of the exhibition type enterprise website include the design of the website CI, layout, mode of browsing, interactivity, text, tone, value of content, honor of the site and so on.

機房建置,如何根據行業來選擇服務器配置?

機房建置,對於企業來說網站是企業重要的門戶,然而不同企業對於網站服務器託管的方式會隨着企業的需求而變化。

一般來說,大型網站都是從小型網站發展而來,初始階段的網站架構都比較簡單,隨着業務複雜和用戶量的激增,纔開始做很多架構上的改進。當它還是小型網站的時候,沒有太多訪客,一般來講只需要一臺服務器就夠了,這時應用程序,數據庫,文件等所有資源都在一臺服務器上。
但隨着網站業務的發展和用戶量的增加,一臺服務器就無法再滿足需求了。大量用戶訪問導致訪問速度越來越慢,而逐漸增加的數據也會導致存儲空間不足。這時就需要將應用和數據分離,應用和數據分離後整個網站使用3臺服務器,分別是應用服務器,文件服務器和數據庫服務器。這3臺服務器對硬件資源的要求越來越高,它們需要更強大的CPU、更快的磁盤和更大的內存去支撐這些服務器運行。
隨着用戶的持續增加,網站又會一次面臨挑戰:數據庫壓力太大導致整站訪問效率再此下降,用戶體驗受到影響。一個網站,往往大部分的業務訪問集中在20%的數據上。就拿微博來說,微博請求量最多的肯定是那些千萬級粉絲的大V的微博,而幾乎沒有人去關注那些小號的首頁。我們可以利用這個特點,把這一小部分數據先提前緩存在內存中,而不是每次都去數據庫讀取,這樣就可以減少數據庫的訪問壓力,從而提高整個網站的訪問速度。網站使用的緩存一般分爲緩存到應用服務器或者緩存在專門的分佈式緩存服務器。緩存到應用服務器的訪問速度快很多,但是受自身內存限制,往往不太適用。遠程分佈式緩存使用一個集羣專門負責緩存服務,當內存不夠還可以輕鬆得動態擴容。
使用應用服務器集羣改善網站的併發處理能力使用緩存後,數據訪問壓力得到了緩解,但是單一應用服務器能夠處理的請求連接有限,在網站訪問高峯期,應用服務器就成了整個網站的效率瓶頸。當一臺服務器的處理能力和存儲空間不足時,不要嘗試去更換更強大的服務器,對大型網站而言,多麼強大的服務器,都滿足不了網站持續增長的業務需求。這種情況下,更恰當的做法是增加一臺服務器分擔原有服務器的訪問及存儲壓力。對網站架構而言,只要能通過增加一臺服務器的方式改善負載壓力,就可以以同樣的方式持續增加服務器不斷改善系統性能,從而實現系統的可伸縮性。應用服務器實現集羣是網站可伸縮架構設計中較爲簡單成熟的一種。

Datacenter migration, how to choose PDU power supply cabinet

Datacenter migration, not only to ensure the security of the data center under high temperature and rainy weather, stability operations, but also reduce operating costs of enterprises overall under pressure, but many in the bidding process is not the PDU with UPS as single row, column head cabinet, cabinets and other equipment, PDU parameters also is very not clear, even some just indicate the power supply socket, this will cause a lot of late work: matching with equipment, non-standard distribution, shortage of budget, etc., the above situation is called bids from both sides don't know how to choose matching PDU power?

How did PDU help the engine room survive the summer?
The intelligent PDU can help the computer room to survive the summer. The intelligent PDU also says that the remote control of power outlet is to meet the requirements of the microenvironment monitoring application of the computer room.On the basis of PDU, the external temperature and humidity monitoring of current voltage is added.
1. Compared with basic PDU, intelligent PDU has irreplaceable advantages:
Basic PDU can only provide basic power distribution function.And intelligent PDU in addition to provide current, voltage and protection, also can provide various advanced features, such as electric power metering, environmental monitoring and remote port control, implements effective and reliable operation for the entire data center monitoring and management, can help reduce the operating costs of data center, improve the uptime, reliability, improve equipment mean time to repair resolution (MTTR) for customer-impacting events caused, be more effective in their data center electricity use, also can realize the existing data center capacity and asset management.
2. Powerful mechanism design of intelligent PDU, which can withstand the toughest external conditions:
Senior input wire connection, stress release and durable, compared with the general low cost type organization, more powerful, chassis side firmly, without punching or vents, prevent particles contact internal conductors, there will be no short circuit, and the heat radiation safety;Small space footprint, with the best access characteristics, airflow characteristics, easy to install physical;The maximum ambient temperature (60C/140F) can be tolerated, and safe operation can be realized even under the condition of the highest layout density and continuous loading.Output socket connection phase alternating design, easy to tie cable, higher load balancing efficiency.
3. Ensure the safety and efficiency of summer operation and maintenance with powerful monitoring and management functions:
The output power monitor of socket port detects the actual redundancy, implements the most effective load balancing, and provides the detailed status of each power supply of the server.Gigabit Ethernet port, and has the auxiliary network connection as a backup, to ensure that monitoring and reliability, and implement IT network and the construction management of insight to share at the same time, high efficiency Power IQ management interface intuitive type, can be to check the equipment energy consumption, hot and PUE, carried out on the heat and Power load balancing.
How to select PDU power supply?
(1) select suitable products according to their specific conditions;
(2) select the product of normal manufacturer (some manufacturers may also be a normal manufacturer, of course, but pdus may not be the advantage products, when the choice should be discreet, although a vet is a doctor, but I can't think he is also a famous doctor, as long as a doctor you see a doctor can't find him);
(3) the state has relevant quality inspection and certification for all kinds of products. When choosing PDU products, we should first look at the qualifications of the manufacturers and then the quality certification of the products.
(4) integrated above, and then understand related products after-sales service (it is a good product, no one can guarantee there is no bad, so the after-sales service is also a key issue, and after-sales service not only by mouth, suggested that the ground to take root, by words)
1. The attention paid to PDU in different periods of machine room construction
Bidding planning phase selection: a lot of room and there is no the PDU with UPS as single row, column head cabinet, cabinets and other equipment, PDU parameters also is very not clear, even some just indicate the power strip, this will cause a lot of late work problems: namely not matching with other equipment, non-standard distribution, shortage of budget, etc., both sides of this phenomenon is the main reason for bidding is not clear how the PDU labeling requirements?Here's a simple way to do it:
(1) power of the circuit of the distribution branch of the header cabinet + safety margin = the total power of PDU on this line;
(2) the number of equipment + safety margin in a cabinet = the number of holes in all PDU in the cabinet. If there are two redundant lines, the number of PDU should be doubled with the same parameters.
(3) distribute the high-power equipment in different PDU as far as possible to balance the current of each phase;
(4) the PDU's pore type is customized based on the device plug that cannot be separated from the power cord. If the device plug that can be separated from the power cord is not compatible, the power cord can be replaced to solve the problem.
Cabinet inside the devices (5), high density PDU it is advisable to choose multiple tap vertical loading, low density inside the cabinet equipment, PDU it is advisable to choose less jack lateral finally to quote PDU separate budget in order to avoid a serious shortage of budget.
2. Installation and commissioning period:
(1) the power of the power distribution socket in front of the cabinet should be matched with the power of the circuit of the distribution branch of the column header cabinet and the power of PDU, otherwise, the power index of use will be reduced;
(2) when installing PDU horizontally, the installation U of PDU should be reserved. When installing PDU vertically, the position of the lateral rail plate on the side of the cabinet should be in line with the installation size of PDU.
(3) the double-round European standard plug cannot be directly inserted into the universal hole, so the grounding will be suspended and very dangerous.The correct method is to replace the plug or use the embedded European standard jack, no more using the European standard to convert the national standard's special conversion line.
3. Operation period:
(1) pay attention to the temperature rise index, that is, the temperature change of the device plug and PDU jack;
(2) if there is a PDU with remote monitoring, the current change of PDU can be observed to determine whether the equipment is working normally.
(3) make full use of PDU's wiring device to decompose the external release force of the device plug on the socket.
4. In summary: in fact, the following is all that matters when selecting customized models:
(1) customized PDU process: what is the total current (about 50% redundancy according to the total power of the output device);
(2) input part: the length of the cable (usually 2-3 meters is enough);
(3) the wire diameter is determined by the total current, and the power supply environment of the front end is determined by the total current and the power supply environment of the front end.The number of output sockets, a few for each socket, the domestic multipurpose interface used more;
(4) protection function selection (lightning protection, overload, digital display, power indicator, automatic switching of dual power supply, remote monitoring, etc.);
(5) installation method selection (horizontal or vertical installation)
(6) product material: steel plate or profile shell.

What matters do website design Professional company to pay attention?

Website design is now an information age, if an enterprise can build its own website. Then we can keep up with the times, publicize the products of enterprises and set up the image of enterprises. Therefore, it is necessary to build enterprise websites. But a successful website is often not so easy to build, so what do the web design companies need to pay special attention to in the design of the web site?

1. The independent development of the web page or the template set
There are many websites with templates on the market. They are stereotyped and are not good for search engines.
2. The server / virtual host space needs to be branded
The most important thing is to choose a regular IDC service provider to buy a server. Many small space vendors are now renting a cheap server trusteeship, then dividing space and selling them to users. Although it is cheap, they often have problems, either the host is unstable, or the machine is often dead, or the security is poor or service state. Degree difference. But in fact, we really need to support a lot of components, support multi user concurrency, speed of the excellent host, the host is generally a lot of host to share a wide band, website design professional companies remind you: if you visit a large number of websites, more data, it is necessary to buy exclusive, best not To share, although it is more expensive, but in the long run, it must be bought, otherwise there will be a lot of trouble in the operation stage of the website.
3. The planning and investigation of the website before building
According to the purpose of visiting users, draw up the theme that the website should focus on. The theme of website planning is the cornerstone and core of the whole website planning, and is the basic criterion of website planning.
4, customer experience is the most important, the layout of the imagination and renovations is refreshing.
Website design professional companies should pay attention to website structure and layout design, web structure and layout design is good, pleasing to the eye, convenient for customers to identify memory. And the core technology of the program is very important. Others can't steal it, so it's also safe.
5, the update of form and content
Good website design content and form will bring real amount of visits to the website. However, the renewal of websites needs to pay attention to efficiency: daily updating as far as possible, quantity index, content specialization and news information aging.
6. The goal is clear and the positioning is accurate.
Website design professionals need to be clear: what kind of visitors? What do you do on the website? What is the core of the website? What is the service that can be provided? What is the model point of profit? In view of the psychological marketing design of potential customers, the creation of a product, brand or enterprise in the target customer's image or certain personality characteristics, to retain a profound impression and unique position.
7. The theme is bright and distinctive.
The theme is clear, clear and clear, with simple and clear language and picture to tell the theme of this site, to attract the needs of the site of the people's sight, to the unrelated people can also leave a certain impression. For some industry signs and company logo, we should make full use of them. Mobilize all means to fully display the personality and interest of the website, highlight individuality and create the characteristics of the website.
8. The layout and layout of the layout are reasonable
Layout design expresses harmony and beauty through spatial combination of text and graphics. The website design professional company does the layout design through the rational analysis of the visual elements, and the strict form of training, training the overall picture to grasp the ability and aesthetic ability. Efforts should be made to rationalize, orderly and integrate the overall layout. At this point, Wang Qinger believes that excellent works are good at making the ideas of some languages unexpressed in an ingenious and rational way of vision, so as to be rich and diverse and concise. In order to achieve the best visual performance, we should pay attention to the rationality of the overall layout. In particular, there are closely related contextual pages, which must be designed with buttons forward and backward, so that visitors can read them carefully.
9. Color harmony and emphasis
Website design professional companies use color to the psychological impact of the results of the rational use. According to the principle of color memory, the general warm colors are more memorable than cool colors. Color also has the characteristics of association and symbolization. For example, red symbolizes fire, blood and sun; blue symbolizes the sea, sky and water. Therefore, it is necessary to use negative and quiet colors to make people feel cool.
10, the harmony and unity of form and content
Form serves the content, content serves the purpose, and the unity of form and content is one of the basic principles of designing web pages.

企業機房建置,如何增強基礎架構的可擴展性?

機房建置,自數據中心出現以來,企業的它經理們就一直糾結於努力尋求對數據中心資源進行配置處理的最佳方式。而伴隨着服務器虛擬化,雲計算和大數據等技術的發展,這一過程變得更加複雜。而在本文中,業內的相關專家就將幫助我們廣大讀者朋友們就如何更好的解決貴公司在服務器硬件策略方面的管理難題進行解疑,並還將爲您介紹關於如何識別和解決數據中心網絡性能問題的相關方法,以及實施服務器規模化擴展的優缺點,以便幫助您瞭解如何採購可擴展的虛擬基礎架構。識別和解決網絡性能問題企業數據中心的它經理們花時間來調查可用於監控網絡I / O的方法,並確定可能導致網絡速度變慢的原因是非常值得的。如果企業應用程序的所有者報告稱:網絡連接速度慢,那麼確保其原因不是由廣域網中的瓶頸所導致的是至關重要的。網絡性能不佳通常可歸因於虛擬化之外的原因。可能存在尚未報告或發現的停機中斷或路由問題。另一個亟待檢查的領域是IP配置。而一些簡單的工具如萍,pathping,路徑跟蹤程序和網路資訊查詢在診斷網絡問題時仍然有用。最常見的問題之一是錯誤或不正確的域名服務器(DNS)配置。另一個亟待檢查的領域是虛擬機(VM)中應用程序的配置。查看是否存在會顯著降低網絡性能的設置或選項,也許是應用程序的輪詢網絡,以查找外部網絡組件的可用性——那麼這可能會導致不必要的網絡流量。一旦你企業排除了上述這些潛在的問題,就需要確認優化組件是否配置正確。接下來,檢查網絡問題是否僅影響相關虛擬機或同一主機上的所有虛擬機。這也是確定相關問題是否特定於應用程序所有者的虛擬機或者是否是系統性問題的好方法。大多數虛擬機管理程序供應商均提供了相應的網絡工具,以方便企業客戶監控進出虛擬機的流量。例如,VMware公司就提供了一款名爲esxtop的實用程序,可以查看網絡統計信息,並排除網絡性能問題。這些實用程序允許數據中心的運營管理人員查看虛擬機實際使用的網絡帶寬,以及是否檢測到物理系統出現大量的網絡數據包的被丟。它們還能夠顯示系統的發送和接收速率。當一款機器發出數據包,但未收到確認時,可能表示網絡接口卡(NIC)的算法存在問題,稱爲反向NIC團隊問題。在這種情況下,已啓用高級網卡綁定,雖然數據包通過一個網絡層離開物理主機,但它們通過錯誤的物理交換機返回到主機,並返回到錯誤的NIC。像這類嚴重的問題可能需要更廣泛的調查。在某些情況下,可能會導致放棄特定的NIC組合策略,這對於更廣泛的網絡來說被認爲是不可靠的。隨着整合比率的增長,可以做大量工作來改進和監控虛擬機的網絡性能。最佳優化的關鍵在於遵循虛擬化供應廠商的最佳實踐方案,同時對其進行修改以適應企業網絡的獨特流量特性。最關鍵的部分是瞭解你企業的虛擬機和更廣闊的物理環境之間的關係。橫向或縱向規模化擴展:如何通過數據中心升級實現進一步的發展演變在它領域,舊的問題最終會演變成新的問題,這個道理在數據中心服務器方面正在發揮作用。根據技術商業研究(創業)有限公司公司數據中心研究部門高級分析師基督教佩裏表示:“我們當前正再次看到企業對其系統實施縱向規模化擴展的興趣的增強,而這一方案曾一度處於下滑趨勢。”自數據中心出現以來,企業的它經理們一直在努力處理如何最好地配置其資源的問題。而他們的這個選擇方案基本上是在採購更大的硬件或更多的硬件之間:橫向或縱向規模化擴展嗎?1,服務器橫向擴展的優缺點分析服務器的橫向擴展的概念意味着向系統添加更多節點或購買更多硬件。例如,一家公司可以從一款Web服務器系統發展到三個。在極端情況下,數百臺小型計算機被配置爲集羣,這些集羣足夠支持大型數據中心的計算能力。橫向擴展通常很簡單。企業可以購買新系統並快速啓動。該方法也很靈活:可以以一種看似有限的方式添加系統,儘管其最終將需要更多的數據中心空間。實際上,橫向擴展的方法在雲服務供應商中很受歡迎,因爲該方法可以構建能夠支持數千個客戶和PB級數據存儲的海量數據中心。Facebook Inc .公司的開放計算項目就鼓勵橫向擴展服務器。該公司並不是依賴來自諸如惠普,IBM和甲骨文等傳統服務器廠商的特殊用途的系統,而是將通用硬件設備捆綁在一起,並構建巨大的數據中心。包括蘋果,Facebook和谷歌在內的網絡領軍企業都選擇了這種方式來支持他們的業務。當然,橫向擴展系統也有其缺點,首當其衝便是複雜性。太多計算機的連接會增加管理的複雜性,並且您必須支持更復雜的編程模型,由於存在多個本地系統,因此會在節點之間出現吞吐量和延遲問題,所以很難進行故障排除。

2,服務器縱向擴展的優缺點分析
服務器的縱向擴展可以避免服務器蔓延的問題。系統縱向擴展使用專門爲科學計算或高端數據庫管理系統應用而設計的專門開發的處理器。通常情況下,企業客戶通過向單臺服務器添加計算資源來建立自己的數據中心,並使其更加強大,企業安裝更強大的處理器,更多的內存或更多的內部網絡資源來提升性能,會得到更大規模的硬件。
由於低成本的x86服務器的出現,規模的縱向擴展一直在減少。企業無需爲處理能力支付高的價,而是可以購買價格較低的硬件。其結果是,科學計算機市場急劇萎縮,Unix市場一直在失去對於企業的吸引。
最近的一些轉變似乎正在爲這個細分市場注入新的活力。縱向擴展與虛擬化技術很好地結合在一起。使得企業客戶能夠通過軟件將其工作負載增加到一個系統上,而不是實際增加新的系統。現在,企業客戶可以在一款中央系統上運行數百個應用程序。通過虛擬管理程序部署新的虛擬服務器通常比實際採購和安裝物理服務器要便宜。
諸如惠普和IBM等成熟的供應商正在提供打包的解決方案。供應商們不是僅僅提供簡單的硬件設備,而是配置他們的系統,以便包含應用程序所需的所有組件.TBR的佩裏表示:“隨着大數據等應用的興起,企業客戶希望快速部署,從而更快的實現規模化的縱向擴展。”
這些整體解決方案與另一種趨勢保持了一致:更多的業務部門的需求將影響到企業的它採購。根據市場調研機構Gartner Inc .公司發現,它企業的首席營銷官現在擁有與CIO們同等的採購權限。因此,當前的企業的業務經理能夠在很少或根本沒有來自它員工的意見的前提下選擇採購一款整體解決方案,比傳統系統採購延遲更少。
而這員工面臨的挑戰就是支持橫向擴展系統。選擇自行採購他們所需系統的業務部門需要它部門支持,來確保這些系統的健康運行。
縱向擴展規模也只是一個臨時的解決方案。這種技術增加了數據中心的密度,並且通常需要特殊的冷卻和電源設施。每次當企業客戶投資更多的服務器硬件時,都會花費更多的時間,但最終並沒有一臺服務器能夠滿足應用程序的負載。
隨着縱向擴展基礎設施規模化的重新出現,它企業縱向擴展規模較之橫向擴展的選擇更加困難。唯一可以肯定的是,計算機的使用正在擴大,企業正在努力跟上業務增長的步伐。
爲可擴展的虛擬基礎設施採購服務器硬件
隨着服務器虛擬化,雲計算和大數據分析等技術朝着數據中心領域的進一步滲透發展,它專業人員在服務器硬件的採購方面有了新的選擇。數據中心需要能夠滿足企業業務對於性能和可用性快速增長的設備的需求,並且還將隨着未來幾年它需求的變化,進一步提供相對容易的可擴展性。
企業組織可以選擇購買少量的新型的功能強大的服務器,並採用縱向擴展的策略,這使得少數服務器得以能夠處理大量的工作負載,同時消耗更少的能源。另外,他們可以選擇一種橫向擴展的方法,使用大量功能較弱的商品化服務器,這樣可以實現集羣和冗餘,而且這種架構在前期的投入成本可能會更便宜。
當前,這兩種服務器硬件策略都有其各自的市場,但是現在需要注意的是:可擴展的計算能力已經以橫向模型取代了傳統的縱向擴展的服務器硬件體系結構模型。接下來,我們將分析這種轉變及其在現代數據中心環境中是如何形成的。
1,服務器橫向擴展和縱向擴展戰略各自的優缺點
在過去的十年中,隨着企業的它領導者開始使用某些指標(如服務器整合率和虛擬主機數量)來衡量它性能,服務器的縱向擴展架構成爲了一項選擇策略。基於這些指標以及節省硬件成本的願望,那部門通過使用幾臺功能強大的服務器轉向持續的服務器整合,這些服務器可以承擔大量的工作負載,從而最大限度地利用昂貴的資源。底層虛擬化軟件的許可成本也降低了,由於許多主流應用程序的分離性質,在需要時簡單地添加資源變得非常容易。企業組織同時也在橫向擴展規模,但只有縱向擴展規模才能達到實際的限制,例如在單一主機服務器中達到物理資源的最大限度時。
然而,今天,隨着工作負載的增加和新的業務需求的不斷出現,橫向擴展架構重新興起,並開始影響到企業它服務器硬件的採購方式。通過利用原始計算能力,而不是分散工作負載的計算能力,橫向擴展工作負載正在解決當今企業的許多最關鍵的挑戰,例如,大數據分析需要能夠以主要計算能力爲目標的數據集。這種計算能力可以通過部署許多連接在一起的較小系統來實現共同目標而獲得。這種類型的系統也非常適合雲環境,可以承受實際無限的計算能力。一家企業組織甚至可以將雲服務視爲整體橫向擴展策略的附加平臺。總的來說,雲服務供應商可以根據企業客戶的需求提供大型的縱向規模環境或更小的橫向擴展環境。
當然,這兩種架構都有其不足之處。縱向規模化擴展的方案很少提供資源的線性增長,通常僅支持一種或兩種資源,例如,在縱向擴展以儘可能少使用主機服務器的廣義虛擬環境中,RAM和磁盤容量通常在達到處理器容量之前耗盡,在資源方面並沒有獲取其中的最大資本價值。縱向規模化擴展架構還需要更詳細的方法以實現其可用性。另一方面,橫向擴展環境可能需要考慮應用程序設計的新方法,並且可能不適用於傳統的應用程序。
有鑑於此,重要的是要注意:橫向擴展與縱向擴展並不是互相排斥的。我們將看到企業組織同時運行縱向擴展環境以滿足傳統和運營需求;以及橫向擴展環境以滿足研究或計算密集型需求的現象將越來越普遍。
2,選擇服務器硬件進行虛擬化
用不同的應用程序部署方法來運行這些應用程序的不同硬件平臺。在主要的縱向擴展環境中,底層硬件的功能扮演着非常關鍵的角色,而橫向擴展環境則可能能夠充分利用市場上出現的商品化硬件。
在過去十年中,虛擬化技術的發展使x86服務器成爲大多數企業運行其關鍵任務工作負載的首選平臺。在許多情況下,x86服務器取代了傳統的大型主機,儘管傳統大型機今天依然在各個方面發揮着作用。
例如,雖然許多人認爲VMware公司創造了虛擬化技術,但是大型主機已經使用了類似技術來實現工作負載分離有幾十年的時間了。當今不斷增長的環境,無論是橫向擴展還是縱向擴展都與大型主機有許多共同之處,因爲當今大多數環境都與管理資源分配的主調度系統的硬件組件緊密集成。然而,鑑於x86和商品化硬件的成本下降,以及新興基礎設施的出現,目前看到企業組織正在大規模採購單一主機的情況越來越罕見。
企業它採購人員知道在採購x86服務器以滿足縱向擴展虛擬化需求時會發生什麼。簡而言之,對於純粹的縱向擴展的虛擬化,儘可能擴展單臺主機的能力通常是決定性因素。這樣做可以降低虛擬化許可的總體成本。
在某些情況下,根據操作環境大小的不同,企業客戶可能會考慮大規模擴展的硬件,例如極高端,密集型服務器,其中包括數十款處理器內核,太字節的RAM和海量存儲。在這種情況下,最大的挑戰也許是單臺硬件設備出現故障時可能出現的工作負載故障。
隨着企業組織努力控制多虛擬環境中出現的複雜性,一些新興的基礎設施選項越來越受歡迎。兩者都圍繞融合基礎設施構建,但程度不同。
第一種解決方案基本上是一臺機架(或一組機架)中的數據中心:選擇虛擬化方案的企業將在預構建的,預先測試的硬件平臺上進行整合,並由單一供應商提供支持。這些解決方案中最受市場認可的解決方案可能是思科系統,EMC和VMware所提供的Vblock,但其他公司也已經採取了行動以爭取市場份額,例如戴爾的音速啓動解決方案。這些基礎設施選項使客戶能夠購買滿足當前需求的“基礎設施單元”,而無需擔心某些元素是否與其他元素兼容。從支持的角度來看,這些解決方案非常棒,可以爲企業組織提供很多安心的選擇。
但是,一次就完成對於機架的採購並不總是最好的選擇,特別是對於中小型企業(SMB)而言,事實上,小型企業組織可能更加意識到簡化數據中心環境的必要性,並且可能必須以更細化的方式來實現。
而這便是第二種基礎設施選項:超融合基礎設施發揮其用武之地的時候了。目前,Nutanix,Pivot3和SimpliVity等公司在這一領域處於領先地位。這些公司不是簡單地使用現有的服務器和存儲,而是提供定製化的基礎架構單元,這些單元從SMB級別開始並逐步擴展到大型企業級別。這些單獨的硬件單元各自包括計算單元,RAM和存儲資源,並且通常在這些資源類別中的每一箇中都包括了高級特徵(例如,用於存儲的重複數據刪除)以使其有效性最大化。因爲它們所具備的細粒度,使得這些超融合基礎架構單元的功能非常強大,同時,因爲這些超融合基礎架構通常包含高級硬件,使得每項元素都可以提供大量的資源。

What are the factors that must be considered in datacenter migration?

Datacenter migration is not a simple thing, the construction of data center is an integral structure, any details, ignore is likely to lead to the happening of the problem, and involved in the problems of details, and eventually lead to its design and construction of the result often is not very ideal, causing delays and need to rework, to make matters worse, it will be a troubling problem for a long time, the merits of the planning and design, and only after the system is running to make objective assessment, a lot of problems to after a long time, even a life cycle of equipment or system to be exposed, to avoid data center construction completion of delivery,Due to the delay in the construction period caused by the failure to consider the problems during construction, the rework is required. The following are the key issues to ensure that the data center planners adhere to the correct direction.
A comprehensive data center room construction generally includes: integrated wiring, anti-static floor laid, roof and wall decoration, partition decoration, ups power supply, constant temperature and humidity air conditioning, computer room environment and power equipment monitoring and control system, air system, leak detection, ground system, lightning protection system, access control, monitoring, fire control, alarm, shielding engineering, etc.

Ii. Main aspects of the construction of data center machine room
1. Fire control system
The air extinguishing system should be set up in the machine room, and the air bottle room should be set outside the machine room. It is a tubular network structure and a nozzle should be set on the top of the ceiling.Gas fire control system should be adopted in the fire control system of the machine room
2. Precision air conditioning system
The role of the computer room precision air conditioning system is to ensure room equipment can continuous, stable and reliable operation, equipment and other heat sources need to discharge the telecom room send out quantity of heat, maintain a constant temperature and humidity in the room, the air dust content and control room.Therefore, the precision air conditioning system of the machine room is required to have the ability of air supply, air return, heating, humidifying, cooling, dehumidifying and air purification.Precision air conditioning system of machine room is the most important equipment to ensure good environment of machine room.
3. Monitoring and access control system
There are a large number of servers, cabinets and racks in the monitoring booth.As these cabinets and racks are generally relatively high, there are more dead ends for monitoring. Therefore, the main consideration is to install cameras between each row of cabinets in the TV monitoring layout.If there is a large space at each entrance and exit, the camera with zoom can be considered. Between each row of cabinets, a fixed focus camera can be equipped according to the monitoring distance.If there are multiple rooms in the machine room, consider installing cameras in the ups room and the control room.
The door control system of the machine room adopts non-contact intelligent IC card integrated management system.The system can flexibly and conveniently stipulate the personnel, time and authority to enter the machine room, prevent the destruction caused by human factors and ensure the security of the machine room.
4. Shielding system
Electromagnetic interference has a great impact on computer equipment, which may cause misoperation and data loss, or make the computer unable to work.The shielding in the machine room mainly prevents various electromagnetic interference damage to the equipment and signal in the machine room. There are two common types: metal mesh shielding and metal plate shielding.Electromagnetic interference within the computer room in our country's requirement: the room radio interference field strength in the frequency range of 0.15 ~ 1000 MHZ is not greater than 120 db, room interference field strength in the magnetic field is not more than 800 a/m (rather then 10 oe).According to room size is different to the requirement of shielding, shielding the discretion of the frequency spectrum, material and construction method of shielding system selection, the indicators requirements shall be in strict accordance with national standards.
5. Ground system
Room should install a good grounding system, the power of a stable zero potential, as the reference voltage of the power supply system voltage, have a good grounding line, computer power supply voltage of transmission and the met or producing all kinds of interference signal, can through the high and low frequency filter capacitor filter it out.In addition, when encountering lightning, strong power source near the cabinet and electric spark interference, a good machine room grounding system should be able to protect the computer.
Therefore, it is quite important to design a good machine room grounding system. The machine room grounding system is generally divided into the following three types:
Dc to: (1) the grounding system is the power supply output through a fixed ground, making it a stable zero potential, the power supply ground wire directly connected to the earth, and a small grounding resistance;
(2) ac ground: this grounding system connects the ground wire of the ac power to the connection point of the motor, generator and other ac electric equipment, and then to the earth;
Safely (3) : in order to shield interference, leakage and edm, all computer cabinet, chassis, chassis, panels and motor shell needs to be grounded shielding, the system can be used to safely.
General requirements: dc ground resistance is less than 1 ohm, ac ground resistance is less than 4 ohm, and safe ground resistance is less than 4 ohm.Four kinds of grounding devices, such as ac working grounding, safety protection grounding, dc working grounding and lightning protection grounding, are suitable for sharing a set of grounding devices, whose grounding resistance is less than 1 ohm.The grounding system can be connected in various forms, such as radial system, circular system or grid matrix system.
6. Anti-static floor laying
In the construction of machine room, ground project is a very important component, the floor of machine room USES antistatic floor commonly.The movable floor is mainly composed of two parts.A) anti-static movable floor surfaces;B) floor support system, mainly beam support Angle (the support Angle is divided into upper and lower supports, the screw can be adjusted to adjust the floor level).The size is mainly 600*600mm. The laying height is 350 + / - 20mm.
Movable floor has disassemble characteristic, accordingly, the connection of conduit cable of all equipment, conduit and repair change are very convenient.Floor space can be used as a static pressure air supply under wind of library, and through the activities of air distribution tuyere send the room air conditioning cold air into the indoor machine cabinets and heating equipment, air draught on the floor with general floor interchangeability, so are free to adjust the distribution of airflow in the room.The ground surface below active floor needs to undertake moistureproof processing commonly (if rinse moistureproof lacquer, etc.), when antistatic floor is installed, ask to install electrostatic leakage system at the same time.Static electricity leakage network is laid, and the static electricity is leaked by sealing the grounding terminals of the main line and the safe protection ground of the machine room.
7. Power distribution system
1) ups power supply without interruption
Computer room load is divided into main equipment load and auxiliary equipment load.Main equipment load refers to the computer and network system, computer peripheral equipment and machine room monitoring system, this part of the power supply and distribution system is called "equipment supply and distribution system", the power supply quality is very high, ups uninterruptible power supply should be adopted to ensure the stability and reliability of power supply.Auxiliary equipment load refers to air conditioning equipment, power equipment, lighting equipment, test equipment, etc. Its power supply and distribution system is called "auxiliary power supply and distribution system", and the power supply is directly supplied by the municipal power.In the high demand machine room project, ups uninterrupted power supply can adopt the direct parallel technology and its power supply and distribution system is called n+1 redundant parallel technology.It can make sure it has a ups fails, will still be able to provide all the load continuous high reliable power supply, and the need to add capacity, only the existing weaver system directly in parallel, do not need to add new ups power supply system, can effectively save the cost.High quality cable, cable channel and socket should be selected for electrical construction in the machine room.Sockets shall be divided into municipal power, ups and special waterproof sockets for main equipment.
2) power distribution cabinet
The machine room usually adopts special power distribution cabinet to standardize the power supply and distribution system of the machine room, so as to ensure the security and rationality of the power supply and distribution system of the machine room.The distribution box and cabinet shall be protected by short-circuit and over-current, and the emergency power off button shall be interlocked with the fire alarm.After installation, number and indicate the purpose of each switch in the box and cabinet for operation and maintenance.The spare circuit is reserved in the distribution box and cabinet to power the equipment expansion of the machine room.
Above is from the power distribution facilities, weak current control and protection equipment, several problems that should pay attention to construction of computer room for a simple description, actually room construction project is a collection of computer network technology, communication technology, the building decoration, weak current control, air conditioning, electrical, electronic, automatic detection and control, environmental protection, safety and anti-interference multidisciplinary integrated system in the field of engineering.A is advanced, rationality, practicability and expansibility, can show exquisite, unique design, new material and construction at the center of the room, must have certain historical vitality, the following look at the design of the data center room construction insist right direction key problems.
Conclusion:
There are many other considerations in the construction of new data centers.But industry experience tells us that in the process of data center construction and design master this 13 key basic setup key, will ensure that the final data center design as close as possible to the user's real needs.
