FC-AL
An acronym for Fibre Channel Arbitrated Loop topology.
FC adapter
A printed circuit assembly that translates data between the FC host
processor's internal bus and the FC link. This is also known as an HBA, or
Host Bus Adapter.
FC device
A device that uses Fibre Channel communications.
FC-SCSI hardware
path ID
A FC term describing a list of values showing the physical hardware path of
the FC host to the target device.
FC-SW
An acronym for Fibre Channel switched topology. The highest performance
Fibre Channel fabric, providing a choice of multiple path routings between
pairs of F-ports.
fiber
A fiber optic cable made from thin strands of glass through which data in the
form of light pulses is transmitted (LASER, LED). It is often used for high-speed
transmission over medium (200m) to long (10km)distances but it can be used
for short distances (<200m).
fibre
A generic FC term used to cover all transmission media types specified in the
Fibre Channel Physical Layer standard (FC-PH), such as optical fiber, copper
twisted pair, and copper coaxial cable.
Fibre Channel (FC)
A switched protocol that allows concurrent communication among
workstations, supercomputers, mainframes, data storage devices, and other
peripherals. Fibre Channel is capable of transmitting at rates exceeding one
gigabit per second in both directions simultaneously.
Fibre Channel -
Arbitrated Loop
(FC-AL)
One of three existing Fibre Channel topologies, in which 2 to 126 devices are
interconnected serially in a single loop circuit. The arbitrated loop topology
supports all classes of service and guarantees in order delivery of frames
when the source and destination are on the same loop.
Fibre Channel
Protocol for SCSI
(FCP)
FCP defines a Fibre Channel mapping layer (FC-4) that uses FC-PH services to
transmit SCSI command, data, and status information between a SCSI
initiator and a SCSI target. Using FCP enables transmission and receipt of
SCSI commands, data and status, across the Fibre Channel using the
standard Fibre Channel frame and sequence formats.
frame
The smallest, indivisible unit of information transfer used by Fibre Channel.
Frames are used for transferring data associated with a sequence. Frame size
