A Glossary of Terms and Abbreviations

BIOS Basic Input/Output System. Software that provides basic read/write capability.

Usually kept as firmware (ROM based). The system BIOS on a server board is used

to boot and control the system. The BIOS on your host adapter acts as an extension

of the system BIOS.

Configuration The way a computer is setup; the combined hardware components (computer,

monitor, keyboard, and peripheral devices) that make up a computer system, and 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

Validation

A software procedure in which a host queries a device to determine its ability to

communicate at the negotiated data rate.

EEPROM Electronically Erasable Programmable Read-Only Memory. A memory chip

typically used to store configuration information. It provides stable storage for long

periods without electricity and can be reprogrammed. See NVRAM.

External SAS

Device

A SAS device installed outside the computer cabinet. These devices are connected

together using specific types of shielded cables.

Host The computer system in which a storage adapter is installed. It uses the storage

adapter to transfer information to and from devices attached to the SCSI bus.

Host Adapter

Board (HAB)

A circuit board or integrated circuit that provides a device connection to the

computer system.

Internal SAS

Device

A SAS device installed inside the computer cabinet. These devices are connected

together using an unshielded ribbon cable.

Main Memory The part of a computer’s memory which is directly accessible by the CPU (usually

synonymous with RAM).

NVRAM Non-volatile Random Access Memory. An EEPROM (Electronically Erasable

Read-Only Memory chip) used to store configuration information. See EEPROM.

Peripheral

Devices

A piece of hardware (such as a video monitor, disk drive, printer, or CD-ROM) used

with a computer and under the computer’s control. SCSI peripherals are controlled

through a SAS Intel

RAID Controller SASMF8I.
