SCSI cable
A 68-conductor (34 twisted pairs) cable used for differential bus connections.
single-ended SCSI bus
A bus in which 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 Compaq 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 level enclosures
to house the shelves. Standard mounting devices for SBBs are also included.
StorageWorks building block
See SBB.
target
A SCSI device that performs an operation requested by an initiator. Any device on the bus can
be an initiator or a target.
target ID
See SCSI device ID.
termpower
Is an electrical current that is limited by self-resetting fuses.
UltraSCSI
Is an improvement in SCSI technology that was developed by the StorageWorks Engineering
Group at Compaq Computer Corporation , and subsequently standardized by the ANSI SCSI
committee (X3T10), which increases the maximum transfer rate on the SCSI bus from 10 MHz
to 20 MHz (for a Wide SCSI bus this means an increase in maximum bus bandwidth from 20
MB/sec to 40 MB/sec).
