Appendix A Glossary of Terms
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 the 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 DriverDomainValidationEEPROMExternal SCSI DeviceFusion-MPT Architecture

A program that allows a microprocessor (through the operating system) to direct the operation of a peripheral device, such as a disk drive.

A software procedure in which a host queries a device to determine its ability to communicate at the negotiated data rate.

Electronically Erasable Programmable Read Only Memory. A memory chip typically used to store configuration information.

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

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.
