What is Data Storage space Virtualization?

A data storage area virtualization solution lets you reduce the number of physical hardware information needed to support applications. It is doing this by simply abstracting fundamental disk and drive components and aggregating their capacity like a single pool of safe-keeping available to applications for use. This pool of storage can now be managed by a central gaming system to deliver functional and economic benefits like faster resource provisioning and catastrophe recovery features.

The key to storage virtualization is software that intercepts input/output (I/O) requests from physical and virtual machines and routes them to the suitable physical location on a shared pool of storage. To the application, the virtual storage area appears being a single, contiguous disc or logical unit quantity (LUN) to accept standard read and write operations.

While simple storage products, such as solitary hard disk drives and basic disk arrays, do not provide virtually any form of virtualization, advanced disk arrays offer a logical to physical abstraction through RAID systems and a host-based volume supervisor. This type of virtualization enables features like pictures, cloning and replication being supported throughout different vendors.

Network-based storage virtualization is the most common form of the technology. With this approach, a purpose-built system connects to all or any the safe-keeping hardware within an FC or perhaps iSCSI utility area network (SAN) and has them like a single pool of storage. http://www.virtualdataspace.biz/for-progressive-approach-use-board-room-software/ Towards the operating system or perhaps application, the resulting digital disks or LUNs look as though they reside about the same physical disk and have total functionality, including multi-pathing software program.
