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.
