A data storage area virtualization method lets you decrease the number of physical hardware assets needed to support applications. It can this by abstracting root disk http://www.virtualdataspace.biz/box-vdr-main-features/ and drive components and aggregating all their capacity like a single pool area of storage space available to applications for use. This pool of storage can then be managed by a central gaming console to deliver operational and monetary benefits just like faster resource provisioning and catastrophe recovery capacities.
The key to storage virtualization is application that intercepts input/output (I/O) requests right from physical and virtual computers and tracks them to the appropriate physical location on a distributed pool of storage. Towards the application, the virtual storage appears to be a single, continuous hard drive or reasonable unit amount (LUN) to accept regular read and write procedures.
While straightforward storage gadgets, such as solo hard disk drives and basic disk arrays, do not provide any form of virtualization, advanced disk arrays offer a rational to physical abstraction through RAID techniques and a host-based volume administrator. This type of virtualization enables features like pictures, cloning and replication to be supported across different suppliers.
Network-based safe-keeping virtualization is the most common form of the technology. With this approach, a purpose-built device connects to all the safe-keeping hardware in an FC or perhaps iSCSI storage space network (SAN) and signifies them as a single pool of storage. Towards the operating system or perhaps application, the resulting electronic disks or LUNs appear as though that they reside on one physical hard disk drive and have full functionality, including multi-pathing application.
