1.2.7 RAID x0
RAID level-x0 refers to RAID level 30, 50 and 60. RAID x0 is a combination
multiple RAID x volume sets with RAID 0 (striping). Striping helps to increase
capacity and performance without adding disks to each RAID x array. The
operating system uses the spanned volume in the same way as a regular
volume. Up to one drive in each sub-volume (RAID 3 or 5) may fail without loss
of data. Up to two drives in each sub-volume (RAID 6) may fail without loss of
data.
RAID level x0 allows more physical drives in an array. The benefits of doing so
are larger volume sets, increased performance, and increased reliability.
The following illustration is an example of a RAID level x0 logical drive.
Note
RAID level 30, 50 and 60 can support up to eight sub-Volumes
(RAID set). If the volume is RAID level 30, 50, or 60, you cannot
change the volume to another RAID level. If the volume is RAID
level 0, 1, 10, 3, 5, or 6, you cannot change the volume to RAID level
30, 50, or 60.
