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.
