channel

An interface that allows for the high speed transfer of large amounts of data. Another term

for a SCSI bus.

See also SCSI.

chunk

In any form of RAID that stripes data, data is stored in pieces called chunks. One chunk is

stored on each member device in the unit. Taken together, the chunks make up a stripe. The

chunk size can be used in some controllers to tune the stripeset for a specific application.

chunk size

The number of data blocks, assigned by a system administrator, written to the primary

RAIDset or stripeset member before the remaining data blocks are written to the next

RAIDset or stripeset member.

CLCP

Code-Load Code-Patch utility. This utility can be used to download patches to the Array

Controller Software.

CLI

Command Line Interface. A command line entry application used to interface with the

HS-series controllers. CLI enables the configuration and monitoring of a storage subsystem

through textual commands.

coax or

coaxial cable

A two-conductor wire in which one conductor completely wraps the other with the two

separated by insulation.

command line interface

See CLI.

computer interconnect bus

See CI bus.

configuration file

A file that contains a representation of a storage subsystem configuration.

container

(1) Any entity that is capable of storing data, whether it is a physical device or a group of

physical devices. (2) A virtual, internal controller structure representing either a single disk

or a group of disk drives linked as a storageset. Stripesets and mirrorsets are examples of

storageset containers that the controller uses to create units.
