drive. The controller generates parity every time data is written to
the array, and it is distributed in stripes across all the drives.
RAID 10
Dual-level RAID type created by using two or more equal-sized
RAID 1 arrays to create a RAID 0. Both read and write performance
are improved due to array striping. However, the performance
improvement costs additional storage space due to the mirroring of
the arrays.
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.
redundant
The ability of an array to maintain operability when one or more
hardware failures occur. RAID 1 is redundant. In the event of a
drive failure, redundant arrays can be restored to normal operation
by replacing the failed drive and rebuilding the array.
rescan
Process of updating the current screen to show all currently
available resources.
S
segment
Contiguous area of a physical drive that makes up some or all of an
array. When the software creates an array, it automatically converts
space into segments.
