Important
:
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 can-
not change the volume to another RAID level. If the volume is
RAID level 0, 1, 10(1E), 3, 5, or 6, you cannot change the vol-
ume to RAID level 30, 50, or 60.
JBOD
(Just a Bunch Of Disks) A group of hard disks in a RAID box are
not set up as any type of RAID configuration. All drives are avail-
able to the operating system as an individual disk. JBOD does not
provide data redundancy.
Single Disk (Pass-Through Disk)
Pass through disk refers to a drive that is not controlled by the
RAID firmware and thus can not be a part of a RAID volume. The
drive is available to the operating system as an individual disk.
