Precisely what is Storage Virtualization?

Storage virtualization, as the name signifies, is a technology that pools physical storage information from multiple devices into what appears to be a single pool of available storage capacity. This capacity can now be presented to servers, VMs and uncovered metal computers in a virtual environment for the reason that logical storage space.

The technology relies on computer software to identify and aggregate physical http://myvirtualstorage.blog storage capacity from hard disk drive, optical, adhesive tape, solid-state and other storage units into a shared pool of logical potential that can be were able by a central console. Even more storage components can be added mainly because needed and joined to the pool, thus expanding it is overall capability.

Block-level virtualization (block aggregation) is a common form of safe-keeping virtualization that presents a couple of physical hard disk drives to an request as one rational device. This kind of virtualization often improves performance simply by abstracting the logical travel from the actual storage.

Network-based storage virtualization is also a trendy form of virtualization. It attaches to storage space devices on the Fibre Route (FC) or perhaps Internet Little Computer System Software (iSCSI) SAN and presents these people as a pool area of storage space that is available to all members from the SAN.

Data replication is another common apply for storage virtualization. It provides a common place to replicate data across several systems against failures also to facilitate data migration.

Virtualization also offers a way to extend the life of more aged storage systems by adding these people as a rate of storage space to the virtualized pool. This can reduce administration costs and free up space on the storage system that is not currently being utilized.
