Important:
RAID level 30, 50 and 60 can support up to eight sub-Vol-
umes (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.
JBOD
(Just a Bunch Of Disks) A group of hard disks in a RAID box
are not set up as any type of RAID conguration. All drives are
available 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 rmware and thus can not be a part of a RAID volume. The
drive is available to the operating system as an individual disk.
