(FC-AL) A fast serial bus interfacestandard intended to replace SCSI on high-end servers.FC-AL has a number of advantages over SCSI. It offers higherspeed: the base speed is 100 megabytes per second, with 200,400, and 800 planned. Many devices are dual ported, i.e., canbe accessed through two independent ports, which doubles speedand increases fault tolerance. Cables can be as long as 30 m(coaxial) or 10 km (optical). FC-AL enablesself-configuring and hot swapping and the maximum numberof devices on a single port is 126. Finally, it providessoftware compatibility with SCSI.Despite all these features FC-AL is unlikely to appear ondesktops anytime soon, partly because its price, partlybecause typical desktop computers would not take advantageof many of the advanced features. On these systems FireWirehas more potential.[Current status? Reference?]
