Caching
Allows data to be stored in a pre-designated area of a disk or RAM. Caching
speeds up the operation of RAID systems, disk drives, computers and
servers, or other peripheral devices. See also Cache.
CD-ROM
Compact Disk-Read Only Memory, a removable read-only storage device,
similar to an audio compact laser disk, holding up to 640MB of data.
Channel
Any path used for the transfer of data and control of information between
storage devices and a storage controller or I/O adapter. Also refers to one
SCSI bus on a disk array controller. Each disk array controller provides at
least one channel.
Cluster
A group of terminals or workstations attached to a common control unit or
server, or a group of several servers, that share work and may be able to back
each other up if one server fails.
CMOS
Complementary Metal Oxide Semiconductor, a chip that packs many
components onto a very small semiconductor.
Cold Swap
The physical exchange of a replacement unit in a storage system for a
defective one. The exchange requires human intervention and power must be
removed from the storage system in order to perform the exchange (compare
to Warm Swap, Hot Swap, and Auto Swap).
Controller
An adapter card, RAID controller, or other module that interprets and
controls signals between a host and a peripheral device.
