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 
validation
A software procedure in which a host queries a device to determine its 
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
A SAS device installed outside the computer cabinet. These devices are 
connected using specific types of shielded cables.
Fusion-MPT 
architecture
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.
