Glossary
FC-FLA The Fibre Channel Fabric Loop Attach standard defined by ANSI.
FCP Fibre Channel Protocol; mapping of protocols onto the Fibre Channel
standard protocols. For example, SCSI FCP maps SCSI-3 onto Fibre
Channel.
FC-PH-1, 2, 3 The Fibre Channel Physical and Signalling Interface standards
defined by ANSI.
FC-PI The Fibre Channel Physical Interface standard defined by ANSI.
FC-PLDA The Fibre Channel Private Loop Direct Attach standard defined by
ANSI. Applies to the operation of peripheral devices on a private
loop.
FC-SW-2 The second generation of the Fibre Channel Switch Fabric standard
defined by ANSI. Specifies tools and algorithms for the
interconnection and initialization of Fibre Channel switches in order
to create a multi switch Fibre Channel fabric.
Fibre Channel
Transport
A protocol service that supports communication between Fibre
Channel service providers. See also FSP.
Fill Word An IDLE or ARB ordered set that is transmitted during breaks
between data frames to keep the Fibre Channel link active.
Firmware The basic operating system provided with the hardware.
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. See also F_Port and Fx_Port.
FLOGI Fabric Login; the process by which an N_Port determines whether a
fabric is present, and if so, exchanges service parameters with it. See
also PLOGI.
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.
FRU Field replaceable Unit; a component that can be replaced on site.
