FC-AL-3. The Fibre Channel Arbitrated Loop standard
defined by ANSI. Defined on top of the FC-PH
standards.
FCC. Federal Communications Commission.
FC-FLA. The Fibre Channel Fabric Loop Attach
standard defined by ANSI.
FCMGMT. Fibre Alliance Fibre Channel Management.
FCP. See Fibre Channel protocol.
FC-PDLA. The Fibre Channel Private Loop Direct
Attach standard defined by ANSI. Applies to the
operation of peripheral devices on a private loop.
FC-PH-1,2,3. The Fibre Channel Physical and
Signaling Interface standards defined by ANSI.
FC-PI. The Fibre Channel Physical Interface standard
defined by ANSI.
FCS switch. See fabric configuration server switch.
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
multiswitch Fibre Channel fabric.
Fibre Channel (FC). A technology for transmitting data
between computer devices at a data rate of up to 4
Gbps. It is especially suited for attaching computer
servers to shared storage devices and for
interconnecting storage controllers and drives.
Fibre Channel arbitrated loop (FC-AL). A standard
defined on top of the FC-PH standard. It defines the
arbitration on a loop where several FC nodes share a
common medium.
Fibre Channel protocol (FCP). The protocol for
transmitting commands, data, and status using Fibre
Channel FC-FS exchanges and information units. Fibre
channel is a high-speed serial architecture that allows
either optical or electrical connections at data rates from
265 Mbps up to 4-Gbps.
Fibre Channel service (FS). A service that is defined
by Fibre Channel standards and exists at a well-known
address. For example, the Simple Name Server is a
Fibre Channel service. See also Fibre Channel service
protocol.
Fibre Channel service protocol (FSP). The common
protocol for all fabric services, transparent to the fabric
type or topology. See also Fibre Channel service.
Fibre Channel shortest path first (FSPF). A routing
protocol used by Fibre Channel switches.
Fibre Channel transport. A protocol service that
supports communication between Fibre Channel service
providers. See also Fibre Channel service protocol.
field replaceable unit (FRU). An assembly that is
replaced in its entirety when any one of its components
fails. In some cases, a field replaceable unit can contain
other field replaceable units.
File Transfer protocol (FTP). In Transmission Control
protocol/Internet protocol (TCP/IP), an application
protocol used for transferring files to and from host
computers.
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.
FLA. Fabric loop attach.
flash partition. Two redundant usable areas, called
partitions into which firmware can be downloaded in the
2109 Model M12.
FLOGI. See fabric login.
FL_port. See fabric loop port.
F_port. See fabric port.
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,
and so on) and data frames.
frame delimiter. A part of an ordered set that marks
frame boundaries and describes frame contents. See
also ordered set.
FRU. See field replaceable unit.
FS. See Fibre Channel service.
FSP. See Fibre Channel service protocol.
FSPF. See Fibre Channel shortest path first.
FTP. See File Transfer protocol.
full duplex. A mode of communication that allows the
same port to simultaneously transmit and receive
frames. See also half duplex.
Fx_port. A fabric port that can operate as either a
fabric port (F_port) or fabric loop port (FL_port). See
also fabric port and fabric loop port.
