Chapter A Glossary of Terms and Abbreviations Active Termination BIOS Configuration Device Driver Differential SCSI Domain Validation EEPROM External SCSI Device Fusion-MPT Architecture Host Host Adapter Board (HAB) Internal SCSI Device Main Memory 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. 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 adapter acts as an extension of the system BIOS. 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. A program that allows a microprocessor (through the operating system) to direct the operation of a peripheral device. 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 is a software procedure in which a host queries a device to determine its ability to communicate at the negotiated Ultra320 data rate. Electronically Erasable Programmable Read Only Memory. A memory chip typically used to store configuration information. See NVRAM. 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 now. 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. A circuit board or integrated circuit that provides a device connection to the computer system. A SCSI device installed inside the computer cabinet. These devices are connected together using an unshielded ribbon cable. The part of a computer's memory which is directly accessible by the CPU (usually synonymous with RAM). 31
