Fibre channel


Fibre Channel, or FC, is a high-speed network technology (commonly running at 1, 2, 4, 8, 16, 32, and 128 gigabit per second rates) primarily used to connect computer data storage to servers. Fibre Channel is mainly used in storage area networks (SAN) in commercial data centers. Fibre Channel networks form a switched fabric because they operate in unison as one big switch. Fibre Channel typically runs on optical fiber cables within and between data centers.

Most block storage runs over Fibre Channel Fabrics and supports many upper level protocols. (FCP) is a transport protocol that predominantly transports SCSI commands over Fibre Channel networks.Mainframe computers run the FICON command set over Fibre Channel because of its high reliability and throughput. Fibre Channel can be used for flash memory being transported over the NVMe interface protocol.

To promote the fiber optic aspects of the technology and to make a unique name, the industry decided to use the British English spelling fibre for the standard.

Fibre Channel is standardized in the T11 Technical Committee of the International Committee for Information Technology Standards (INCITS), an American National Standards Institute (ANSI)-accredited standards committee. Fibre Channel started in 1988, with ANSI standard approval in 1994, to merge the benefits of multiple physical layer implementations including SCSI, HIPPI and ESCON.
