array controller See controller.
asynchronous Events scheduled as the result of a signal requesting the event or that which is
without any specified time relation.
audible alarm The Environm ental Monitoring Unit (EMU) alarm that sounds when there is a
drive enclosure element condition report. The audible alarm can be muted
or disabled.
backplan e An electronic printed circuit board that distributes data, control, power, and
other signals to element connectors.
bad block A data block that contains a physical defect.
bad block replace-
ment
A replacement routine tha t substitutes defect-free disk blocks for those found to
have defects. This process takes place in the controller a nd is transparent to
the host.
bail lock Part of the power supply AC receptacle that engages the AC power cord
connector to ensure that the cord cannot be accidentally disconnected.
baud The maximum rate of signal state changes per second on a communication
circuit. If each signal state change corresponds to a code bit, then the baud
rate and the bit rate are the same. It is also possible for signal state changes
to c orrespond to more than one code bit so the baud rate may be lower than
thecodebitrate.
bay The physical location of an element, such as a drive, I/O module, EMU or
power supply in a drive enclosure. Each bay is numbered to define its location.
bidirectional Also called Bi-Di. The movement of optical signals in opposite directions through
a common fiber c able such as the data flow path typically on a parallel printer
port. A parallel p ort c an provide two-way data flow for disk drives, scanning
devices, FAX operations and even parallel mo dem s.
block Also called a sector. The smallest collection of consecutive bytes addressa
ble on
a disk drive . In integrated storage elements, a block contains 512 bytes of data,
error codes, flags, and the block address header.
blower A variable speed airflow device that pulls air into an enclosure or element. It
usually pulls air in from the front and exhausts the heated air out the rear.
cabinet Analternatetermusedforarack.
cable assembly A fiber o ptic cable tha t has connectors installed on one or both end s. General
use of these cable assemblies includes the interconnection of multimode fiber
optic cable assemblies with either LC or SC type connectors.
• When there is a c onnector on only one end of the cable, the cable assembly
is referred to as a pigtail.
• When there is a connector on ea ch end of the cable, the cable assembly
is referred to as a jumper.
CAC Corrective Action Code. An HP Command Vi ew EVA graphical user interface
(GUI) display component that defines the action required to correct a problem.
See also read cache,write cache,andmirrored cache.
cache High-speed memory that sets aside data as an intermediate data b uffer b etween
ahostandthestoragemedia.Thepurposeofcacheistoimproveperformance.
cache bat ter y A rechargeable unit mounted within a controller enclosure that supplies back-up
power to the cache module in case of p rimary power shortage.
