Brief on storage area network

qa-featured

A storage area network (SAN) is a dedicated high-speed network that interconnects and offers shared pools of accommodation devices to various servers.

A SAN moves storage resources off the common user network and reorganizes them into an independent, high-performance network. This enables each server to access shared storage as if it were a drive directly attached to the server. When a host wants to access a storage device on the SAN, it sends out a block-based access request for the storage device.

ADVANTAGES;

  • Great availability.
  • Greater fault susceptibility.
  • Centralized storage management.
  • Faster backups.
  • Global file systems.

Rapid data movement.
