Adaptec 2200S Build, Bus, Cache, Capacity, Channel, Chunk, Clear, Concatenation/concatenating

Glossary

build

Background initialization of a redundant array. The array is accessible throughout. RAID 5 generates parity based on the current contents of the member segments while RAID 1 copies the contents of one (master) drive to a second (slave) drive.

bus

See channel.

C

cache

Fast-access memory on the controller that serves as intermediate storage for data that is read from or written to devices.

capacity

Total usable space available in megabytes or gigabytes.

channel

Any path used for the transfer of data and the control of information between storage devices and a storage controller. Each controller's channels are identified by a number from 0 to the maximum number of channels minus one. Also known as a bus.

chunk

See stripe.

clear

Foreground initialization of a fault-tolerant array. A clear operation zeros all blocks of the array. The array is not accessible until the clear task is complete.

CLI

Command Line Interface. The CLI provides a text-based means of configuring and managing components running on the controller.

concatenation/concatenating

Joining of physical or logical drives in sequential order.
