SCSI device
A single unit on a SCSI bus that originates or services SCSI
commands. A SCSI device is identified by a unique SCSI address.
SCSI devices can act as initiators or targets.
SCSI ID
The number assigned to each SCSI device attached to a SCSI
channel. Each device has its own unique SCSI ID. Also known as
the target ID or SCSI address. See also channel; disk ID; enclosure
ID.
slot
A receptacle in an enclosure for inserting and removing a SCSI
device. See also enclosure.
SMART
Stands for Self-Monitoring Analysis and Reporting Technology.
This technology is designed to determine the reliability status of a
disk drive. If the SMART system determines that a disk drive
failure is imminent, the user is notified and advised of the
appropriate action to take.
small computer system interface (SCSI)
SCSI is an industry standard for connecting peripheral devices and
their controllers to an initiator. Storage devices are daisy-chained
together and connected to a host adapter. The host adapter
provides a shared bus that attached peripherals use to pass data to
and from the host system. Examples of devices attached to the
adapter include disk drives, CD-ROM drives, optical disks drives,
and tape drives. In theory, any SCSI device can be plugged into
any SCSI controller.
spare
A disk drive that you designate as a replacement disk drive as part
of the spare pool. If a disk drive in a redundant array fails, the
controller looks for a spare disk drive on which to rebuild the data
of the failed disk drive.
spare pool
One or more disk drives that you designate as replacements for
any arrays on a controller.
stand-alone
Stand-alone configuration refers to a storage system in which the
controller operates autonomously.
