SAN (Storage Area Network) is a widely used network type consisting of consolidated, block-level data and Fibre Channel (FC) has become one of leading protocols to connect computer data storage to servers. Fiber Channel Protocol uses special purpose hardware called Fibre Channel switches that connect the storage to the Fibre Channel HBAs (Host Bus Adapters) that connect these switches to server computers. Fibre Channel is a mature low-latency, high-bandwidth, high-throughput protocol. As a storage protocol, Fibre Channel is simple to configure and administer, and has had wide adoption over the past years by Data Centers, Enterprises and in Internet Service Provider and Mobile Operator Core Networks. Leading equipment vendors specializing in Fiber Channel switches are: Broadcom (Brocade), HP, Cisco and main vendors specializing in HBAs are QLogic and Emulex.
