Storage Area Network (SAN) usually uses Fiber Channel (FC) technology to connect storage arrays and server hosts through FC switches, and set up regional network dedicated to data storage.

Fiber Channel (FC) is a high-speed network interconnection technology (usually running rates of 2Gbps, 4Gbps, 8Gbps, 14Gbps and 28Gbps), which is mainly used to connect data center storage devices, but it also becomes a common connection type in enterprise class storage SAN.
