Seconds of time.
Service Action Code. Code developed to indicate possible FRU or FRU's to
replace to repair the hardware.
Serial attached SCSI interface.
A data cartridge that contains no useful data, but can be written to with new
data.
Small computer system interface.
A part.
Select.
To change from parallel-by-byte to serial-by-bit.
A device that converts a space distribution of simultaneous states
representing data into a corresponding time sequence of states.
An adjective for use in qualifying some part or aspect of a servomechanism.
A feedback control system in which at least one of the system signals
represents mechanical motion.
A standard used by computer manufacturers for attaching peripheral
devices (such as tape drives, hard disks, CD-ROM players, printers, and
scanners) to computers (servers). Pronounced "scuzzy". Variations of the
SCSI interface provide for faster data transmission rates than standard
serial and parallel ports (up to 160 megabytes per second). The variations
include:
v Fast/Wide SCSI: Uses a 16-bit bus, and supports data rates of up to 20
MBps.
v SCSI-1: Uses an 8-bit bus, and supports data rates of 4 MBps.
v SCSI-2: Same as SCSI-1, but uses a 50-pin connector instead of a
25-pin connector, and supports multiple devices.
v Ultra SCSI: Uses an 8- or 16-bit bus, and supports data rates of 20 or 40
MBps.
v Ultra2 SCSI: Uses an 8- or 16-bit bus and supports data rates of 40 or
80 MBps.
v Ultra3 SCSI: Uses a 16-bit bus and supports data rates of 80 or 160
MBps.
v Ultra160 SCSI: Uses a 16-bit bus and supports data rates of 80 or 160
MBps.
Sense.
A feature that can be ordered to enhance the capability, storage capacity, or
performance of a product, but is not essential for its basic work.
