FC-AL (Fibre Channel Arbitrated Loop)
in which up to 126 nodes are connected in a loop topology. See also
Arbitrated loop.
A device that employs Fibre Channel-Arbitrated Loop and
FC-AL Device
consists of one or more NL_Ports.
A thin filament of glass. An optical waveguide consisting of a core
Fiber
and a cladding which is capable of carrying information in the form of
light. Fiber is also a general term used to cover all physical media types
supported by Fibre Channel, such as optical fiber, twisted pair, and
coaxial cable.
In a library storage context, fiducials may be "fiducial labels" or
Fiducial
"fiducial tabs," allowing reliable identification of cartridge magazines
and drive sleds, including both location and media domain information.
In the Scalar i500 tape library, a "fiducial tab" refers to the plastic locator
tabs which are installed on the media storage columns. The robot
determines the location of these tabs to identify media storage locations.
A "fiducial label" refers to the barcode label on cartridge magazines or
drive sleds which identify magazine or drive sled type.
A set of security tools designed to separate an internal network
Firewall
from the public Internet in order to keep unauthorized users out of a
restricted network. Firewalls are the primary line of security defense for
businesses.
Fabric Loop Port. An F_Port that is capable of supporting an
FL_Port
attached Fibre Channel Arbitrated Loop. An FL_Port on a loop will have
the AL_PA hex'00' giving the fabric the highest priority access to the
loop. N_Ports or NL_Ports can attach to it in an Arbitrated Loop topology
and are capable of communicating with FC-AL protocol.

transmitting data across traditional LANs. GigE is an enhanced version of
the Ethernet protocol that has been used for many years as the
underlying transport technology in IP networks.
