disk drive
Physical disk drive. Randomly accessible, rewriteable data storage device. Also called hard disk, hard drive,
or hard disk drive.
E
event
Notification or alert from the system, indicating that a change has occurred.
event log
File used to maintain information about prior controller activities or errors.
I
Input/Output (I/O)
An operation, program, or device that enters data into or extracts data from a system.
L
Low Voltage Differential (LVD)
Introduced with Ultra2 SCSI, and further enhanced with Ultra160 and Ultra320 SCSI, LVD technology
enables data transfer to 320MB/s and supports cable lengths to 12 meters.
Q
Quick Arbitration Select (QAS)
An Ultra320 SCSI feature that improves the control release between SCSI devices, reducing command
overhead
S
SCSI bus
A SCSI card and one or more SCSI peripherals connected by cables in a linear chain configuration. The
SCSI card may exist anywhere on the chain, allowing connection of both internal and external SCSI
devices. A system may have more than one SCSI bus by using multiple SCSI cards.
SCSI card
An adapter card that includes all of the I/O logic, software, and processing to manage the transfer of
information between the host computer's bus and devices via a SCSI bus.
SCSI device
A device such as a SCSI card board, fixed disk drive, or CD drive that is an initiator or a target or both, and
is attached to a SCSI bus cable.
SCSI ID
A unique identification number used for each device on the SCSI chain.
Small Computer System Interface (SCSI)
The technology that connects various devices to PCs using a SCSI card that fits inside a system.
T
termination
A feature that stops the data signal at the beginning and the end of the SCSI bus. The first and last devices
on the SCSI bus must be terminated.
