Glossary
FC-3 The Fibre Channel layer that provides a set of services common
across multiple node ports (N_Ports) of a Fibre Channel node. The
services are not commonly used and areessentiallyreserved for Fibre
Channel architecture expansion.
FC-4 The Fibre Channel layer that provides mapping of Fibre Channel
capabilities to upper level protocols (ULPs), including IP and SCSI.
FC-AL Acronym for Fibre Channel arbitrated loop. Synonymous with arbitrated
loop.
FC-PH See Fibre Channel Physical and Signaling Interface.
feature enablement
key
After purchasing a an additional product feature, McDATA provides
a unique feature enablement key to the customer. A feature key is a
case-sensitive alphanumeric string consisting of dashes, uppercase
characters, and lowercase characters.
fiber optics The branch of optical technology concerned with the transmission of
radiant power through fibers of transparent materials such as glass,
fused silica, or plastic. A single optical fiber or a nonspatially aligned
fiber bundle is used for each information channel.
fibre A generic Fibre Channel term used to describe transmission media
types specified in the FC-PH standard, such as optical fiber, copper
twisted pair, or copper coaxial cable.
Fibre Channel An integrated set of ANSI standards that defines specific protocols
for flexible information transfer. Logically, Fibrechannel isa point-to-
point serial data channel structured for high performance.
Fibre Channel
Physical and Signaling
Interface
An ANSI document that specifies the FC-0 (physical signaling),
FC-1 (data encoding), and FC-2 (frame construct) layers of the Fibre
Channel protocol.
Fibre Channel
Standard
An ANSI standard that provides a common, efficient data transport
system that supports multiple protocols. The architecture integrates
both channel and network technologies, and provides active,
intelligent interconnection among devices. All data transmission is
isolated from the control protocol, allowing use of point-to-point,
arbitrated loop, or switched fabric topologies to meet the needs of an
application.
