Glossary
adapter
The board that interfaces between the
host system and the target devices.
Adapter is synonymous with Host Bus
Adapter, Host Channel Adapter, host
adapter, and adapter board.
adapter port
A port on the adapter board.
adapter port beacon
An LED on the adapter. Flashing it enables
you to locate the adapter.
alias
A user-defined name for an adapter,
adapter port, logical disk, or subsystem.
API
Application programming interface. A set
of routines, protocols, and tools for
building software applications. API simpli-
fies development by providing the building
blocks.
bandwidth
A measure of the volume of data that can
be transmitted at a specific transmission
rate. A 1Gbps or 2Gbps Fibre Channel
port can transmit or receive at nominal
rates of 1 or 2Gbps, depending on the
device to which it is connected. This corre-
sponds to actual bandwidth values of
106MB and 212MB, respectively.
basic input output system
See BIOS.
BIOS
Basic input output system. Typically in
Flash PROM, the program (or utility) that
serves as an interface between the
hardware and the operating system and
allows booting from the adapter at startup.
boot code
The program that initializes a system or an
adapter. Boot code is the first program to
run when a system or a device within a
system, such as an adapter, is powered
on. FCode, BIOS, and extensible firmware
interface (EFI) are all forms of boot code
for specific hardware/operating system
environments.
Boot code for QLogic Fibre Channel
Adapters is required if the computer
system is booting from a storage device
(disk drive) attached to the adapter. The
primary function of the boot code is
communication with the external boot
device before the operating system is up
and running. Boot code can also perform
secondary functions, including managing
the setup for the adapter and initializing
and testing the adapter’s ISP.
boot device
The device, usually the hard disk, that
contains the operating system the BIOS
uses to boot from when the computer is
started.
