A Storage Area Network is a high-speed sub network of shared storage devices. A SAN's architecture works in a way that makes all storage devices available to all servers on a LAN or WAN. A Storage Area Network can be anything from two servers on a network accessing a central pool of storage devices to several thousand servers accessing many millions of megabytes of storage.
A SAN(Storage Area Network) is a network specifically dedicated to the task of transporting data for storage and retrieval. It is an alternative for storing data on disks directly attached to servers which are connected through general purpose networks. SAN uses special switches like director switch or Network Interface Cards as a mechanism to connect the devices in network. Currently, SANs are implemented using communication protocols such as ISCSI, ESCON, or FCIP. SAN comes into focus when there is need for a effective disaster recovery processes by using RAID technology.
