Chapter A
Glossary of Terms and Abbreviations
Active
Termination
The electrical connection required at each end of the SCSI bus, composed of active voltage
regulation and a set of termination resistors. Ultra SCSI, Ultra2 SCSI, Ultra160 SCSI, and
Ultra320 SCSI require active termination.
BIOS
Basic Input/Output System. Software that provides basic read/write capability. Usually kept
as firmware (ROM based). The system BIOS on the mainboard of a computer is used to boot
and control the system. The SCSI BIOS on your host controller acts as an extension of the
system BIOS.
Configuration
Refers to the way a computer is setup; 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.
Differential
SCSI
A hardware configuration for connecting SCSI devices. It uses a pair of lines for each signal
transfer (as opposed to Single-Ended SCSI which references each SCSI signal to a common
ground).
Domain
Validation
Domain Validation is a software procedure in which a host queries a device to determine its
ability to communicate at the negotiated Ultra320 data rate.
EEPROM
Electronically Erasable Programmable Read Only Memory.
External SCSI
Device
A SCSI device installed outside the computer cabinet. These devices are connected together
using specific types of shielded cables.
Fusion-MPT
Architecture
Fusion-MPT (Message Passing Technology) architecture 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 now.
Host
The computer system in which the RAID controller is installed. It uses the RAID controller
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 SCSI
Device
A SCSI 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
NonVolatile Random Access Memory.
