FC (Fibre Channel)
A high speed data transfer architecture. Using optical fibre to connect devices, Fibre Channel
communications are serial communications that occur at full duplex and achieve data transfer rates of 200
MBps.
FC-AL (Fibre Channel Arbitrated Loop)
A form of Fibre Channel network in which up to 126 nodes are connected in a loop topology. See also
Arbitrated loop .
FC-AL Device
A device that employs Fibre Channel-Arbitrated Loop and consists of one or more NL_Ports.
Fiber
A thin filament of glass. An optical waveguide consisting of a core 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.
Fiducial
In a library storage context, fiducial refers to the reliable identification of media, including both location and
media type information. For example, in a library a fiducial label is a barcoded label that provides the library
with location and media type information for three designated containers: magazines in I/E stations, storage
slots, and tape drive sleds.
Firewall
A set of security tools designed to separate an internal network 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.
FL_Port
Fabric Loop Port. An F_Port that is capable of supporting an 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.
FMR (Field Microcode Replacment) tape
See FUP (Firmware Upgrade) tape .
FRU (Field Replaceable Unit)
The smallest hardware component that can be replaced at a customer installation by a certified field service
representative.
FUP (Firmware Upgrade) tape
A tape that can be used as an alternative to upgrading firmware with SCSI or host.
Gb E or GigE (Gigabit Ethernet)
A transport protocol used for 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.
GUI (Graphical User Interface)
A computer environment that provides a visual view of a system by incorporating windows, icons, menus,
and a pointing device. Also referred to as a Windows, Icons, Mouse, and Pointers (WIMP) interface.
HDD (High Density Drive)
A drive that contains increased storage capacity of bits and/or tracks per square inch.
Home position
Accessor axes positioned at 0 vertical and 0 horizontal, that serve as the point of reference for the position
of other library components. Home position is used as a basis for calibration.
Host
In general, a host is a computer or program that contains data and provides services to other computers or
devices. In Fibre Channel terms, a host is a computer that initiates contact with storage devices.
