A data storage virtualization option lets you reduce the number of physical hardware information needed to support applications. And also this by abstracting actual disk and drive components and aggregating the capacity like a single pool area of storage space available to applications for use. This pool of storage can now be managed by a central gaming console to deliver operational and economical benefits just like faster resource provisioning and disaster recovery capacities.

The key to storage virtualization is computer software that intercepts input/output (I/O) requests from physical and virtual computers and routes them to the right physical location on a shared pool of storage. For the application, the virtual safe-keeping appears as a single, continuous hard disk drive or rational unit quantity http://virtualdataspace.biz/for-progressive-approach-use-board-room-software (LUN) to accept typical read and write functions.

While straightforward storage equipment, such as single hard disk drives and basic drive arrays, do not provide virtually any type of virtualization, advanced disk arrays offer a reasonable to physical abstraction through RAID schemes and a host-based volume director. This type of virtualization enables features like pictures, cloning and replication to become supported throughout different distributors.

Network-based safe-keeping virtualization is the most prevalent form of the technology. From this approach, a purpose-built product connects to any or all the safe-keeping hardware within an FC or iSCSI storage space network (SAN) and positions them being a single pool of storage. For the operating system or perhaps application, the resulting online disks or perhaps LUNs show up as though they reside on a single physical hard drive and have full functionality, including multi-pathing application.
