Data center migration, tape storage "reborn"

Data center migration,Today's enterprises or organizations are very dependent on their computer systems and the information they store. The data continued to grow exponentially, and the demand for data storage continued to increase.

In fact, data storage has become a hot topic, because organizations need to consider how to store the massive amounts of data they are generating. The increase in the content generated by the user, and the increasing pressure from the compliance, have caused the information storage to be the focus of the future for a long time.
Only increasing more storage capacity to meet the growth of data is no longer a feasible strategy for those organizations that need to compress budget, physical space, power and management resources. So there are some modern storage solutions based on the principle of high density and low power consumption.
A modern storage infrastructure
Is there a new technology or strategy that can help companies overcome the challenges that exceed their budgeted data growth? The answer is: No, no. However, there is a technology that has existed for quite a long time to meet all the storage requirements of today's organization.
Some want to realize the organization of modern storage system, and find that they can use flash memory, disk and tape to create storage infrastructure, so that they can store data in the balance of access speed and affordability. In this case, the magnetic tape provides the maximum density and the lowest power consumption.
In recent years, tapes are considered to be a dying data center technology, but with the continuous development of data and storage environment, they remain relevant because of their high density and low energy consumption. Although the disk based solution is often considered for data protection scene, contrary to the traditional tape, but for most organizations, the important question is not in the two kinds of technology to choose between, but how in the storage architecture in the modern effective use of them.
To put it simply, the decision of storage should come from a balanced "equality", which includes business requirements and maximizing the ROI of every storage device.
The reason for the growth of explosive data
For a long time, organizations of all sizes need to work hard to cope with more and more "key business information" and "other information". There are many reasons behind this unusual growth of data, which are different in the organization, but mainly in the following areas:
1, organizations require more detailed information about products, services and customers, which will influence business strategy, drive growth and improve service level (business applications and data warehouses).
2. User driven unstructured content growth, such as images, video and audio, and more traditional content.
3. The need for risk reduction is affected by internal policies and compliance with external regulations, requiring longer data storage.
IT managers are less concerned about the growth of this index - level data and are more concerned with how to store these data. This work is particularly heavy in the area of backup and archival storage, because the company's data is kept longer.  The key challenge for organizations is to balance storage requirements and budgetary needs, meet business needs and protect company data from many threats that may cause disastrous data loss.
The last idea
The role of disk and tape has been "back up" in the data center and is a complement to the implementation of the best practice strategy. The organization can use the high performance of disk and flash memory to deal with key business data and use tape to achieve its superior density, life and economy.
In many environments, tapes are no longer the main backup target for important applications with strict recovery and access requirements. However, it continues to maintain its role as the main backup and archiving target of the application, its requirements are not so strict, and it is also true for data protection and total cost of ownership (TCO).
Tapes play an important role in modern storage architecture. In this architecture, the density of data centers needs to keep up with the exponential growth of data that the organizations are facing. It is cost efficient to migrate old backups from more expensive disk - based storage media. If you need to store archived data for a long time, the tape should be the lowest cost and the most reliable data protection medium.
