Glossary of Terms

and Abbreviations

BIOS	Acronym for Basic Input/Output System. Software that provides basic
	read/write capability. Usually kept as firmware (ROM-based). The system
	BIOS on the motherboard of a computer boots and controls the system.
	The BIOS on your host adapter acts as an extension of the system BIOS.
configuration	Refers to the way a computer is set up, the combined hardware
	components (computer, monitor, keyboard, and peripheral devices) that
	make up a computer system, or the software settings that allow the
	hardware components to communicate with each other.
device driver	A program that allows a microprocessor (through the operating system)
	to direct the operation of a peripheral device.
domain	A software procedure in which a host queries a device to determine its
validation	ability to communicate at the negotiated data rate.
drive group	A group of physical drives that combines the storage space on the drives
	into a single segment of storage space. A hot spare drive does not
	actively participate in a drive group.
EEPROM	Acronym for Electronically Erasable Programmable Read-Only Memory.
	It is a memory chip that typically stores configuration information, as it
	provides stable storage for long periods without electricity and can be
	reprogrammed. Refer to NVRAM.

external SAS device

Fusion-MPT architecture

A SAS device installed outside the computer cabinet. These devices are connected using specific types of shielded cables.

An acronym for Fusion-Message Passing Technology architecture. Fusion-MPT consists of several main elements: Fusion-MPT firmware, the Fibre Channel and SCSI hardware, and the operating system level drivers that support these architectures. Fusion-MPT architecture offers a single binary, operating system driver that supports both Fibre Channel and SCSI devices.
