What is Data Storage Virtualization?
17/09/2023
A data storage space virtualization solution lets you reduce the number of physical hardware assets needed to support applications. It can do this by abstracting fundamental disk and drive components and aggregating all their capacity like a single pool area of storage space available to applications for use. This kind of pool of storage is then managed with a central unit to deliver functional and monetary benefits just like faster http://virtualdataspace.biz/box-vdr-main-features resource provisioning and devastation recovery features.
The key to storage virtualization is software program that intercepts input/output (I/O) requests via physical and virtual servers and paths them to the proper physical site on a distributed pool of storage. To the application, the virtual safe-keeping appears as being a single, contiguous drive or reasonable unit quantity (LUN) to accept normal read and write treatments.
While straightforward storage equipment, such as solo hard disk drives and basic disk arrays, tend not to provide any kind of form of virtualization, advanced disk arrays offer a rational to physical abstraction through RAID systems and a host-based volume manager. This type of virtualization enables features like pictures, cloning and replication to get supported across different vendors.
Network-based storage area 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 storage area network (SAN) and has them as a single pool of storage area. To the operating system or perhaps application, the resulting digital disks or perhaps LUNs look as though that they reside on one physical disc and have total functionality, which include multi-pathing software program.
