Fibre Channel (FC) is a data communication protocol, or a transport mechanism that transports information between two end points. FC securely, quickly, and efficiently sends/receives data between a computer (host) and a storage device that is typically a disk or disk array; the host can be any computer from a desktop PC to large server or mainframe.

The FC protocol encapsulates other protocols (primarily SCSI – Small Computer System Interface), allowing the host to store and retrieve data to/from the storage device.
