SCSI
Small Computer System Interface. An ANSI interface defining the physical and
electrical parameters of a parallel I/O bus used to connect hosts to a maximum
of seven devices. The StorageWorks device interface is implemented according to
SCSI–2 standard, allowing the synchronous transfer of 8-bit data at rates of up
to 10 MB/s.
SCSI device
A host computer adapter, a peripheral controller, or a storage element that can be
attached to the SCSI bus.
SCSI device ID
The bit-significant representation of the SCSI addressing that refers to one of the
signal lines numbered 0 through 7. Also referred to as a target ID.
SCSI–A cable
A 50-conductor (25 twisted pair) cable used for single-ended, SCSI bus
connections.
SCSI–P cable
A 68-conductor (34 twisted pair) cable used for differential bus connections.
Small Computer System Interface
See SCSI.
spareset
A pool of disk drives used by the controller to replace failing members of a
RAIDset.
SPD
Abbreviation for Software Product Description. A document that products a legal
description of a product.
storageset
Any collection of containers, such as stripesets, RAIDsets, the SPARESET, and
the FAILEDSET, that make up a container.
StorageWorks
Digital’s family of modular data storage products that allows customers to
design and configure their own storage subsystems. Components include
power, packaging, cabling, devices, controllers, and software. Customers can
integrate devices and array controllers in StorageWorks enclosure to form storage
subsystems.
StorageWorks building block
See SBB.
stripesets
A virtual disk drive with its physical data spread across multiple physical disks.
Stripeset configurations do not include a data recovery mechanism.
