Movement towards virtualization on the storage as well as the server sides will in effect commoditize both, and reduce the relevance of the physical location of both. This will enable the creation of internal clouds and virtual organizations, making it extremely simple to collapse physical data center infrastructure into more manageable virtual entities.
Storage virtualization is accomplished by creating a virtual abstraction layer between physical or virtual servers and the existing physical storage.Once the storage is virtualized and the physical location of data becomes abstracted from the hosts, some interesting opportunities for savings become apparent.Storage provisioning can be accomplished in exactly the same manner across all storage vendors.Tiers of storage can be created, and data can be moved between tiers automatically, while applications continue operations with zero downtime.Vendors will be able to provide capabilities for other data services such as continuous protection and recovery, which in turn may enable organizations to avoid building out that very expensive data center for DR.
All this will simplify the movement and sharing of data in a secure and optimized manner. Since the physical locality of data will no longer be as important (as long as it's secure), some of the functions typically provided internally by IT departments (with an initial focus on backup and DR) can be easily performed by external service providers, which in turn will enable the IT department to focus more on core applications and functions.
The power of storage virtualization in conjunction with Server Virtualization creates an end state vision for the CIO of an efficient, optimized IT infrastructure which reduces costs while providing enhanced services for the provisioning, protection, replication and recovery of data. The reduced infrastructure requirements greens IT by reducing costs for power, cooling, data center floor space, and continuity of operations. When all these benefits are tied together, the message becomes clear. Storage Virtualization can be "The Next Big Thing in Federal Data Center Consolidation."
Storage Virtualization's Impact on the Enterprise:
- Reduced primary storage capacity requirements
- Reduced storage capital investment by 75% with Thin Provisioning
- Reduced replication cost by 90% with WAN-optimized replication
- Eliminated redundant data and reduced backup repository by 95%
- Reduced recovery time of critical applications
- Consolidated storage management operations
