Glossary
extended edge
This format generates the same PID for a port on switches with 16 or fewer ports as would native PID
PID format, but it also supports up to 256 ports per domain. It should be used only in cases where you cannot
upgrade devices to dynamic PID binding and you must not reboot your servers. Extended edge PID is
supported in Fabric OS v2.6.x, v3.1.x, and v4.2.x. See also
Extended An optionally licensed Fabric OS feature that provides up to 500 km of switched fabric connectivity at
Fabrics full bandwidth over long distances.
extent
A range of logical blocks within a logical unit (LU). The path name identifies both the LU of which this
extent is part and the path used to access this extents. See also
extent pair
(ePair) Associates two extents in DMM: a source extent and an appropriate destination extent. This pair
then identifies the migration locations to DMM. See also
F
F_Port
Fabric port. Fabric port on a switch to which an N_Port connects. See also N_Port, and Fx_Port.
fabric
One or more interconnected Fibre Channel switches. The term "fabric" refers to only the interconnected
switches and not to devices connected to the fabric. See also cascade, SAN, and topology.
fabric
A switching device that enables fabric-based storage applications to run within a fabric at wire-speed.
application
The Brocade SilkWorm AP7420 is an example of a fabric application platform. See also
platform appliance.
Fabric
Fabric Manager is licensed Brocade software that resides on a host computer and enables fabric-wide
Manager
GUI management for multiple fabrics in geographically dispersed locations.
Fabric mode One of two possible modes for an L_Port, in which the L_Port is connected to another port that is not
loop capable, using fabric protocol.
fabric name The unique identifier assigned to a fabric and communicated during login and port discovery.
fabric port
The number of ports available to connection SAN devices in a fabric.
count
fabric services Codes that describe the communication to and from any well-known address.
fabric topology
The arrangement of switches that form a fabric.
Fabric Watch An optionally licensed Brocade software. Fabric Watch, accessed through either the command line or
Web Tools, provides the ability to set thresholds for monitoring fabric conditions.
failover On a SilkWorm director, the process of activating the standby CP and transferring switch processing to
this CP. Typically when a failover occurs caused by a problem detected in the active CP, the standby CP
is made active so that traffic is not disrupted. Multiple failovers occur during the firmware download
process, because when new firmware is activated, the CP must be rebooted.
FAN Fabric address notification. Retains the AL_PA and fabric address when a loop reinitializes, if the
switch supports FAN.
