fabric switch
Also, switched fabric. A fabric switch
connects multiple devices from indepen-
dent FC-arbitrated loops (FC-ALs) and
point-to-point topologies into a fabric using
FC switches.

FC
Fibre Channel is a high-speed serial inter-
face technology that supports other higher
layer protocols such as SCSI and IP, and
is primarily used in SANs. Standardized
under ANSI in 1994.
FCode
A type of boot code designed for use on
® ®
Sun 's SPARC or Macintosh
platforms. See also
FCoE
Fibre Channel over Ethernet is a new
technology defined by the T11 standards
body that allows traditional FC storage
networking traffic to travel over an
Ethernet link by encapsulating FC frames
inside Layer 2 Ethernet frames. For more

FL_Port
Fabric loop port. In FC, the fabric switch is
capable of FC arbitrated loop operations
and is connected to one or more NL_Ports
by an FC arbitrated loop. An FL_Port
becomes a shared entry point for public
NL_Port devices to an FC fabric. FL_Ports
are intermediate ports in virtual
point-to-point links between end ports that
do not reside on the same loop, for
example NL_Port to FL_Port to F_Port to
N_Port through a single FC fabric switch.
Flash
Non-volatile memory holding the boot
code. At times, Flash and boot code are
used interchangeably. See also
Flash BIOS
A QLA2xxx adapter's Flash programmable
read-only memory (PROM) contains the
code that allows booting from the adapter
at startup.
G_Port
Generic port. A port that can operate as
either an E_Port or an F_Port. A G_Port
can determine operating mode at switch
port initialization: F_Port when an N_Port
attachment is determined or E_Port when
an E_Port attachment is determined. See
E_Port, F_Port, FL_Port, L_Port, N_Port,
NL_Port.
