Any device that conforms to the SCSI standard and is attached to the
SCSI bus by a SCSI cable. This includes SCSI host adapters and SCSI
peripherals.
A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI
bus has fifteen available SCSI IDs numbered 0 through 15 for Wide SCSI
(or 0–7 for an 8-bit SCSI). The host adapter is assigned ID 7 giving it
priority to control the bus.
Storage Device Management System. An LSI Logic software product that
manages SCSI system I/O.
SCSI Trade Association. A group of companies that cooperate to
promote SCSI parallel interface technology as a viable mainstream I/O
interconnect for commercial computing.
A hardware specification for connecting SCSI devices. It references each
SCSI signal to a common ground. This is the most common method (as
opposed to differential SCSI and low voltage differential SCSI, which
uses a separate return for each signal).
One of the ways data is transferred over the SCSI bus. Transfers are
clocked with fixed-frequency pulses.
Controls the low level POST (Power-On Self-Test), and basic operation
of the CPU and computer system.
The electrical connection required at each end of the SCSI bus,
composed of a set of resistors.
A standard for SCSI data transfers. It allows a transfer rate of up to
20 Mbytes/s over an 8-bit SCSI bus, and up to 40 Mbytes/s over a
16-bit SCSI bus. STA (SCSI Trade Association) supports using the term
"Ultra SCSI" over the older term "Fast-20".
A standard for SCSI data transfers. It allows a transfer rate of up to
40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a
16-bit SCSI bus. STA supports using the term "Ultra2 SCSI" over the
older term "Fast-40".
Voluntary Control Council for Interference.
Very High Density Cable Interconnect.
