Storage virtualization, as the name implies, is a technology that pools physical storage information from multiple devices in to what appears to be a single pool of accessible storage capacity. This kind of capacity can then be presented to servers, VMs and bare metal hosting space in a online environment as logical storage space.

The technology relies on program to identify and aggregate physical storage capacity from disk, optical, record, solid-state and also other storage equipment into a distributed pool of logical potential that can be handled by a central console. More storage hardware can be added because needed and joined to the pool, therefore expanding its overall ability.

Block-level virtualization (block aggregation) is a frequent form of storage virtualization that presents several physical disks to an software as one reasonable device. This kind of virtualization often increases performance by simply abstracting the logical drive from the genuine storage.

Network-based storage virtualization is also a popular form of virtualization. It connects to storage space devices on a Fibre Channel (FC) or perhaps Internet Small Computer System Program (iSCSI) myvirtualstorage.blog/how-much-does-it-cost-to-use-a-data-room/ SAN and presents them as a pool area of storage space that is available for all members for the SAN.

Info replication is another common use for storage virtualization. It possesses a common place to replicate data across numerous systems against failures and also to facilitate data migration.

Virtualization also offers a method to extend the life span of older storage systems by adding all of them as a tier of storage area to the virtualized pool. This may reduce control costs and free up space on the storage system which is not currently being applied.
