Precisely what is Data Safe-keeping Virtualization?

A data safe-keeping virtualization remedy lets you reduce the number of physical hardware means needed to support applications. It lets you do this by abstracting fundamental disk and drive components and aggregating their particular capacity as being a single pool of storage space available to applications for use. This kind of pool of storage can now be managed with a central system to deliver detailed and economic benefits like faster more info here resource provisioning and problems recovery capacities.

The key to storage virtualization is software program that intercepts input/output (I/O) requests right from physical and virtual hosting space and tracks them to the appropriate physical area on a distributed pool of storage. Towards the application, the virtual storage appears being a single, continuous hard drive or rational unit number (LUN) to accept common read and write procedures.

While straightforward storage products, such as single hard disk drives and basic disc arrays, do not provide any sort of virtualization, advanced disk arrays offer a reasonable to physical abstraction through RAID plans and a host-based volume administrator. This type of virtualization enables features like snapshots, cloning and replication being supported around different distributors.

Network-based storage virtualization is the most common form of the technology. In this approach, a purpose-built equipment connects to all the storage hardware in an FC or perhaps iSCSI storage area network (SAN) and positions them as being a single pool area of storage. To the operating system or perhaps application, the resulting virtual disks or LUNs appear as though they reside on a single physical hard drive and have total functionality, including multi-pathing software program.
