A data storage virtualization resolution lets you decrease the number of physical hardware solutions needed to support applications. It will do this simply by abstracting fundamental disk and travel components and aggregating their particular capacity as a single pool of storage space available to applications for use. This kind of pool of storage is then managed with a central unit to deliver operational and economic benefits like faster resource provisioning and problem recovery features.
The key to storage virtualization is application that intercepts input/output (I/O) requests by physical and virtual web servers and paths them to the appropriate physical site on a distributed pool of storage. For the application, the virtual storage space appears as a single, contiguous disc or rational unit number (LUN) to accept regular read and write procedures.
While basic storage products, such as sole hard disk drives and basic hard disk drive arrays, will not provide any kind of sort of virtualization, advanced disk arrays offer a logical to physical abstraction through RAID techniques and a host-based volume manager. This type of virtualization enables features like snapshots, cloning and replication to get supported around different distributors.
Network-based storage space virtualization is the most prevalent form of the technology. Through this approach, a purpose-built equipment connects for all the safe-keeping hardware in an FC or perhaps iSCSI utility area network (SAN) and symbolizes them as a single pool of safe-keeping. http://virtualdataspace.biz/box-vdr-main-features For the operating system or perhaps application, the resulting electronic disks or LUNs seem as though they will reside on a single physical disk and have complete functionality, including multi-pathing computer software.
