FCIA
Fibre Channel Industry Association. An international organization of Fibre Channel industry
professionals. Among other things, provides oversight of ANSI and industry developed
standards.
FCP
Fibre Channel Protocol; mapping of protocols onto the Fibre Channel standard protocols. For
example, SCSI FCP maps SCSI-3 onto Fibre Channel.
Fibre Channel Transport
A protocol service that supports communication between Fibre Channel service providers.
FL_Port
Fabric Loop Port; a port that is able to transmit under fabric protocol and also has arbitrated
loop capabilities. Can be used to connect an NL_Port to a switch.
FLOGI
Fabric Login; the process by which an N_Port determines whether a fabric is present, and if
so, exchanges service parameters with it.
Frame
The Fibre Channel structure used to transmit data between ports. Consists of a start-of-frame
delimiter, header, any optional headers, the data payload, a cyclic redundancy check (CRC),
and an end-of-frame delimiter. There are two types of frames: Link control frames
(transmission acknowledgements, etc.) and data frames.
FS_ACC
Fibre Channel Services Accept. The information unit used to indicate acceptance of a request
for a Fibre Channel service.
FSP
Fibre Channel Service Protocol; the common protocol for all fabric services, transparent to the
fabric type or topology.
FSPF
Fabric Shortest Path First; the routing protocol for Fibre Channel switches.
Full Fabric
The licensing that allows multiple E_Ports on a switch, making it possible to create multiple
ISL links.
Full-duplex
A mode of communication that allows the same port to simultaneously transmit and receive
frames.
