According to statistics, the amount of data stored in the annual growth rate of 50% to 60%.The face of new applications, and increasing storage capacity, business users need to borrow a virtual technology to reduce management complexity and improve efficiency.But with the development of storage technology, the user demand for data, why not completely universal virtual storage technology? This also from the difficulties of virtual storage technology start.
Currently, business users face the greatest pressure that? First, the cost of data storage is constantly increasing; the second is the explosive growth of data storage capacity; third, more complex environment makes the stored data can not be managed.As we all know, there are three ways to achieve virtualization, server-based, based on storage and network-based.Based on storage virtualization means, the aim is to optimize the user-oriented applications.Storage virtualization to solve the first problem is the problem of heterogeneous data management platform.Storage virtualization can be integrated storage systems of different users into a single platform to address the data management challenges, and through the realization of hierarchical storage life cycle management of information to further optimize the application environment.
Virtual storage technology most concern is data security.Because the virtual memory to all the data on a system environment, which is equivalent to put all your eggs in one basket, if spilled, all the eggs will be lost.So once the data is stored into the virtual storage environment, can not be easily removed.This undoubtedly increased the risk of data, investment in security should increase accordingly.
The second virtual storage problem is ignored the huge needs of SMEs in China.Most current virtual storage technology are focused on high-end users, these users a large storage system, not only of equipment, the software used is also very complex, in this case, the virtual storage technology can bring management, costmany advantages.However, SMEs in China has now become the main force in the enterprise market, not the needs of users for the promotion of SMEs in the virtual storage technology so that technology becomes slow.
Hinder the storage virtualization products, and the other is the price factor, which is the focus on the evils of high-end market.For most SMBs face the lack of storage space, buy a large capacity hard drive directly to solve the storage problem, even if the storage space has been wasted, but compared to the use of virtualized storage architecture, large-capacity hard disk is still relatively cost-effective, in addition toSMB storage system is not complicated, there is not much more difficult to manage, these have led to the popularity of virtual storage technology that there are certain difficulties.
In summary, the virtual storage technology is not only a hot topic in the storage vendors, and in the user storage virtualization technology for increasing demands, as people for data security, integrity demands increase, storage systems, IT has becomean important part of the application, the complexity of storage systems, storage systems management has become difficult, I believe that in the near future of virtual storage technology to overcome the difficulties faced, will give business users to improve the efficiency of storage systems, system security and stabilityoperation, reduce total cost of ownership and increase return on investment and effective implementation of other aspects.
