Glossary
fabric attached
devices (FADs)
fabric element
Any active director, switch, or node in a switched fabric.
fabric login
The process by which node ports (N_Ports) establish their operating
parameters. During fabric login, the presence or absence of a fabric is
determined, and paths to other N_Ports are mapped. Specific
operating characteristics for each port, such as buffer-to-buffer credit
(BB_Credit) and data frame size, are also established.
fabric login command
FLOGI. The command that establishes the initial operating
parameters and topology for a fabric. The command is accepted by a
fabric port (F_Port) (D).
fabric loop port
FL_Port. A fabric port (F_Port) that contains arbitrated loop (AL)
functions associated with the Fibre Channel arbitrated loop (FC-AL)
topology. The access point of the fabric for physically connecting an
arbitrated loop of node loop ports (NL_Ports). See also bridge port;
expansion port; fabric port; generic port; hub port; node loop port;
node port; segmented expansion port.
fabric mode
See interoperability mode.
fabric port
F_Port. Physical interface within the fabric that connects to a node
port (N_Port) through a point-to-point full duplex connection. See
also bridge port; expansion port; fabric loop port; generic port; hub
port; node loop port; node port; segmented expansion port.
fabric services
The services that implement the various Fibre Channel protocol
services that are described in the standards. These services include
the fabric controller (login server), name server, and management
server.
fabric switches
A device which allows the communication between multiple devices
using Fibre Channel protocols. A fabric switch enables the sharing
bandwidth and end-nodes using basic multiplexing techniques.
failover
fast/wide SCSI
g-20
End nodes that are attached to ports on FC switches within a fabric.
Automatic and nondisruptive transition of functions from an active
field-replaceable unit (FRU) that has failed to a backup FRU.
See fast/wide small computer system interface.
