The FC-AL (also called just FC) is a type of interface mostly used for storage networking. It is designed for high-end systems with multiple hard drives. A single FC bus can support up to 127 devices, which is much more than the small computer system interface (SCSI) that only supports up to 16 devices. The FC is standardized by the International Committee for Information Technology Standards (INCITS) in the T11 (X3T9.3) Technical Committee.
