About FC-AL Technology
Fibre Channel (FC) is a high-performance serial interconnect standard designed for
bidirectional, point-to-point communication among servers, storage systems,
workstations, switches, and hubs.
Fibre Channel-Arbitrated Loop (FC-AL) is an important enhancement to the FC
standard, developed specifically to meet the needs of storage system interconnects.
Employing a simple loop topology, FC-AL can support both simple configurations
and complex arrangements of hubs, switches, servers, and storage systems.
FC-AL devices employ a high-performance Gigabit serial interface, which supports
multiple standard protocols such as Small Computer Systems Interface (SCSI) and
Asynchronous Transfer Mode (ATM). By supporting these standard protocols,
FC-AL preserves any investment in existing legacy systems, firmware, applications,
and software.
