Glossary
Fabric Port Physical interface within the fabric, which attaches to an N_Port
through a point-to-point full duplex link connection.
Failover The process of detecting a failure on an active Connectrix switch FRU
and the automatic transition of functions to a backup FRU.
Fan-in/Fan-out Terms used to describe the server:storage ratio, where a graphic
representation of a 1:n (fan-in) or n:1 (fan-out) logical topology looks
like a hand-held fan, with the wide end toward n.
A fan-in or fan-out rate is often referred to as just the n part of the
ratio; for example, a 1:6 fan-in is also called a fan-in rate of 6.

FCP A standard Fibre Channel protocol used to run SCSI over Fibre
Channel.
FC-SW The Fibre Channel Fabric standard.
Fibre A general term used to cover all physical media types supported by
the Fibre Channel specification, such as optical fiber, twisted pair, and
coaxial cable.
Fiber optics The branch of optical technology concerned with the transmission of
radiant power through fibers made of transparent materials such as
glass, fused silica, and plastic.
Either a single discrete fiber or a nonspatially aligned fiber bundle
can be used for each information channel. Such fibers are often called
optical fibers to differentiate them from fibers used in
non-communication applications.
Fibre Channel The general name of an integrated set of ANSI standards that define
new protocols for flexible information transfer. Logically, Fibre
Channel is a high-performance serial data channel.
Firmware The program code (embedded software) that resides and executes on
a connectivity device, such as a Connectrix switch, a Symmetrix Fibre
Channel director, or a host bus adapter (HBA).
