MS-9152 ATX Server Board
C
cache
Fast-access memory on the controller that serves as intermediate storage for data
that is read from, or written to, drives.
capacity
Total usable space available in megabytes or gigabytes.
channel
Any path, or
bus
, used for the transfer of data and the control of information be-
tween storage devices and a RAID controller. For Serial ATA channels, each channel
has a single drive capacity.
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.
concatenation
Joining of physical or logical drives in sequential order.
consistency check command
Command that reads all the blocks of a RAID 1 to determine if the blocks are consistent.
Any inconsistent blocks are fixed.
D
dead partition
See
failed
.
dedicated hot spare
Component that can take the place of a failed component only on the fault-tolerant
array to which it is explicitly assigned.
degraded
A redundant (for example, a RAID 1) array in which one or more members have failed.
The data is intact but redundancy has been compromised. Any further failure would
cause the array to fail and result in data loss.
disk
Physical disk drive. Randomly accessible, re-writable data storage device. Also called
hard disk
.
disk ID
Unique disk identifier that consists of the channel number, SATA ID. For example,
(channel:ID:LUN) 1:04:0. See also
channel
.
