Term Definition
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
adapter 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.
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. A memory chip
typically used to store configuration information. See NVRAM.
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 a 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.
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. Actually an EEPROM (Electronically
Erasable Read Only Memory chip) used to store configuration information. See
EEPROM.
PCI and PCI-X
Peripheral Component Interconnect. A high performance local bus specification
that allows connection of devices directly to computer memory. The PCI Local
Bus allows transparent upgrades from 32-bit data path at 33 MHz to 64-bit data
path at 33 MHz, and from 32-bit data path at 66 MHz to 64-bit data path at 66
MHz.
Peripheral Devices
A piece of hardware (such as a video monitor, disk drive, printer, orCD-ROM)
used with a computer and under the computer’s control. SCSI peripherals are
controlled through a SCSI SRCU42X controller (host adapter).
