Storage virtualization, as the name signifies, 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 capacity can then be presented to servers, VMs and bare metal machines in a digital environment as logical safe-keeping.
The technology relies on software to identify and aggregate physical memory space from hard drive, optical, video tape, solid-state and other storage gadgets into a shared pool of logical capability that can be been able by a central console. More storage hardware can be added for the reason that needed and joined for the pool, therefore expanding their overall potential.
Block-level virtualization (block aggregation) is a common form of safe-keeping virtualization that presents a number of physical hard disks to an software as one rational device. This sort of virtualization often elevates performance by simply abstracting the logical travel from the real storage.
Network-based storage virtualization is also a trendy form of virtualization. It connects to storage space devices on a Fibre Funnel (FC) or perhaps Internet Tiny Computer System Software (iSCSI) SAN and presents these people as a pool area of storage area that is available for all members on the SAN.
Info replication is yet another common work with for storage virtualization. It possesses a common place to replicate data across several systems to protect against failures also to facilitate info migration.
Virtualization also offers a method to extend the life span of aged storage devices by adding all of them as a tier of safe-keeping to the virtualized pool. This can reduce operations costs and free ipo preparation process and timeline up space on the storage area system that is not currently being applied.
