SCSI device-side device address

The eight device addresses (target IDs) assigned to the SCSI controller and the

devices it controls.

See also SCSI host-side device address.

SCSI end-bus position

The physical location of a controller, a SCSI bus controller, or a device that

contains the bus terminator.

SCSI host-side device address

The eight device addresses (target IDs) assigned to the host device and the SCSI

controllers and the devices it controls.

See also SCSI device-side device address.

SCSI mid-bus

The physical location of a controller or a device that the SCSI bus passes through

enroute to the controller or device that contains the SCSI bus termination.

SCSI–A cable

A 50-conductor (25 twisted pair) cable used for single-ended, SCSI–2 bus

connections.

SCSI–P cable

A 68-conductor (34 twisted pairs) cable used for differential bus connections.

single-ended SCSI bus

Each signal’s logic level is determined by the voltage of a single wire in relation

to ground.

Small Computer System Interface

See SCSI.

StorageWorks

The Digital set of enclosure products that allows customers to design and

conﬁgure their own storage subsystem. Components include power, packaging,

and interconnections in a StorageWorks shelf. SBBs and array controllers are

integrated therein to form storage subsystems. System-level enclosures to house

the shelves and standard mounting devices for SBBs are also included.

StorageWorks building block

See SBB.

tape

A storage device supporting sequential access to variable sized data records.

tape controller

See controller.

target

A SCSI device that performs an operation requested by an initiator.
