B-3

SCSI Device

Any device that conforms to the SCSI standard and is attached to the
SCSI bus by a SCSI cable. This includes SCSI storage adapters (host
adapters) and SCSI peripherals.

SCSI ID

A way to uniquely identify each SCSI device on the SCSI bus. Each
SCSI bus has eight available SCSI IDs numbered 0 through 7 (or 0
through 15 for Wide SCSI). The storage adapter (host adapter) usually
gets the highest ID (7 or 15) giving it priority to control the bus.

Single-Ended
SCSI

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, which uses a separate ground for each
signal).

TolerANT

A technology developed and used by LSI Logic to improve data integrity,
data transfer rates, and noise immunity through the use of active
negation and input signal filtering.

Ultra SCSI

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.

Ultra2 SCSI

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.

Ultra160 SCSI

A standard for SCSI data transfers. It allows a transfer rate of up to
160 Mbytes/s over a 16-bit SCSI bus.

Ultra320 SCSI

A standard for SCSI data transfers. It allows a transfer rate of up to
320 Mbytes/s over a 16-bit SCSI bus.

VHDCI

Very High-Density Cable Interconnect. This cable is used to connect
external connectors to your storage adapter.
