Storage Area Network (SAN) : 

Storage Area Network (SAN) is a high-speed special-purpose network that interconnects different data storage devices with associated servers and other computing devices. Typically, a storage area network is a part of the overall network of computing resources in a data centre. SANs support disk mirroring, backup, restore, archival and retrieval of archived data, data migration from one storage device to another, and the sharing of data among different servers in a network.

SANs are built up from variety of hardware components. RAID Storage systems, switches, Servers, backup devices, Interface cards and cabling all come together to form a SAN. Devices in the SAN are connected by a high speed, high capacity network. Currently, fibre channel is the most popular technology for SAN implementation because of its high speed, non-blocking architecture, its ability to scale from 1 Gbps to 8 Gbps and beyond, and its flexibility to allow many different high level protocols to operate over its infrastructure.
