What Is Storage Virtualization?

Storage virtualization, as the name indicates, is a technology that pools physical storage assets from multiple devices in what appears to be just one pool of accessible storage capacity. This capacity can now be presented to servers, VMs and bare metal servers in a digital environment since logical safe-keeping.

The technology relies on application to identify and aggregate physical memory space from disk, optical, cassette, solid-state and other storage gadgets into a distributed pool of logical capability that can be managed by a central console. Even more storage components can be added while needed and joined to the pool, therefore expanding it is overall ability.

Block-level virtualization (block aggregation) is a common form of safe-keeping virtualization that presents a lot of physical hard disks to an app as one reasonable device. This type of virtualization often improves performance by abstracting the logical travel from the actual storage.

Network-based storage virtualization is also a common form of virtualization. It links to safe-keeping devices on the Fibre Route (FC) or Internet Small Computer System Program (iSCSI) SAN and presents all of them as a pool area of storage space that is available to everyone members of your SAN.

Data replication is another common employ for storage area virtualization. It provides a common place to replicate info across various systems to protect against failures and also to facilitate data migration.

Virtualization also offers ways to extend lifespan of elderly storage devices by adding these people as a tier of storage to the virtualized pool. This could reduce managing costs and free up space on the storage space system that is not currently being used.
