exported
device
A device that has been mapped between fabrics (a host or storage port in one edge fabric can be
exported to any other fabric by using LSAN zoning).
F
F_BSY Fabric port busy frame. A frame issued by the fabric to indicate that a frame cannot be delivered
because the fabric or destination N_Port is busy.
F_Port Fabric port. A port that is able to transmit under fabric protocol and interface over links. Can be used to
connect an N_Port to a switch. See also FL_Port, Fx_Port.
F_RJT Fabric port reject frame. A frame issued by the fabric to indicate that delivery of a frame is being
denied, perhaps because a class is not supported, there is an invalid header, or no N_Port is available.
fabric A collection of Fibre Channel switches and devices, such as hosts and storage. Also referred to as a
“switched fabric.” See also cascade, SAN, topology.
fabric
application
platform
A device that enables fabric-based storage applications such as mirroring, data migration, snapshots,
and virtual tape. The Brocade SilkWorm Fabric Application Platform can run in a central location,
process data at wire-speed, and reside in existing data paths.
Fabric
Manager
An optionally licensed Brocade software. Fabric Manager is a GUI that allows for fabric-wide
administration and management. Switches can be treated as groups, and actions such as firmware
downloads can be performed simultaneously.
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
count
The number of ports available for connection by nodes in a fabric.
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 can be accessed through either the command
line or Advanced Web Tools, and it provides the ability to set thresholds for monitoring fabric
conditions.
failover Describes the Brocade SilkWorm 12000 process of one CP passing active status to another CP. A
failover is nondisruptive.
FAN Fabric address notification. Retains the AL_PA and fabric address when a loop reinitializes, if the
switch supports FAN.
fan-in The ratio of hosts to storage devices; the view of the SAN from the storage port's perspective.
fan-out The ratio of storage devices to hosts; the view of the SAN from the host port's perspective.
