What Is Storage Virtualization?

Storage virtualization, as the name suggests, is a technology that pools physical storage solutions from multiple devices into what appears to be a single pool of available storage capacity. This capacity can then be presented to servers, VMs and uncovered metal servers in a digital environment seeing that logical storage.

The technology relies on program to identify and aggregate physical memory space from disc, optical, cassette, solid-state and other storage gadgets into a distributed pool of logical ability that can be was able by a central console. More storage components can be added since needed and joined to the pool, therefore expanding it is overall capacity.

Block-level virtualization (block aggregation) is a frequent form of storage space virtualization that presents a number of physical hard disk drives to an app as one logical device. This type of virtualization often helps performance by abstracting the logical drive from the actual storage.

Network-based storage virtualization is also a common form of virtualization. It links to storage devices on the Fibre Funnel (FC) or Internet Tiny Computer System User interface (iSCSI) SAN and presents these people as a pool of storage space that is available to all or any members from the SAN.

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

Virtualization also offers a method to extend lifespan of old storage devices by adding all of them as a tier of storage space to the virtualized pool. This could reduce supervision costs and free up space on the safe-keeping system which is not currently being used.
