What is Fibre Channel?
Fibre channel technology is outlined in the SCSI-3 Fibre Channel Protocol
(SCSI-FCP) standard. Fibre Channel is a high-speed data transport technology
used for mass storage and networking. It connects mainframes, super computers,
workstations, storage devices, and servers.
Fibre Channel supports data transfer rates of 100 Mbytes/sec on copper and optical
interfaces. The QLA2200/2200L board uses a copper interface for short connections
(less than 30 meters); the QLA2200F/2202F/2204F/2212F board uses a multimode
optical interface for intermediate distances (less than 500 meters); the QLA2200G
board uses a GBIC, which can be either a single mode or multimode optical interface
for long distances (greater than 500 meters).
With increased connectivity and performance, Fibre Channel is the technology
preferred and used by system designers.
