Q
quick init
An array initialized using the Quick Init option is available
immediately, with no on-going background controller activity. All
data written to an array that has been quick initialized is protected.
R
RAID
Redundant Array of Independent Disks (alternative definition
Redundant Array of Inexpensive Disks).
RAID 0
A
single-level array
consisting of two or more equal-sized segments
residing on different disks. RAID 0 distributes data evenly across
its respective drives in equal-sized sections called
stripe
s. RAID 0
arrays are not redundant.
RAID 1
Single-level array consisting of two equal segments residing on
two different drives. Provides redundancy by storing identical
copies on two drives.
See also
mirrored array/mirroring
.
RAID signature
The area on each disk reserved for use by the RAID controller.
RAID volume
Concatenates two or more arrays of the same type.
rebuild
Background regeneration of redundant data on a RAID 1.
reconfiguration
Process of expanding an array or migrating an array from one
RAID type to another; changing the
stripe size
of a RAID 0, or
moving a logical device
’
s
segment
s to other disks.
