Glossary
expansion port
Physical interface on a Fibre Channel switch within a fabric, that attaches to an expansion port
(E_Port) on another Fibre Channel switch to form a multi-switch fabric.
See also segmented E_Port.
explicit fabric login
Data field size, supported by an F_Port, that is agreed upon during fabric login.
fabric
Entity that interconnects N_Ports and is capable of routing (switching) Fibre Channel frames
using the destination ID information in the Fibre Channel frame header accompanying the
frames.
fabric element
Any active director or node in a switched fabric.
fabric port
Physical interface within the fabric that connects to an N_Port through a point-to-point full
duplex connection.
failover
Automatic and non-disruptive transition of functions from an active FRU that has failed to a
backup FRU.
FCC-IOC
See Fibre Channel I/O controller.
FE-MIB
See Fibre Channel fabric element.
fiber
Physical media types supported by the Fibre Channel specification, such as optical fiber,
twisted pair, and coaxial cable.
fiber optics
Branch of optical technology concerned with the transmission of light pulses through fibers
made of transparent materials such as glass, fused silica, and plastic.
fiber port module card
Each fiber port module card provides four Fibre Channel connections through duplex small
form factor (SFF) pluggable fiber-optic transceivers.
Fibre Channel
Integrated set of standards recognized by ANSI which defines specific protocols for flexible
information transfer. Logically, a point-to-point serial data channel, structured for high
performance.
