RAID wizard
Configure any additional LUNs as described above. As you configure these
drives, try to keep the number of LUNs per array as low as possible; the best
solution is one LUN per array. Do not worry about using all the maximum
capacity available. Spare space is wasted capacity and should not be planned
for here; it makes no sense and will only make re-configuration at a later date
very complicated. Now think about the RAID levels. RAID levels 0 and 1 are
suitable for groups with up to two hard disk drives. RAID levels 0, 0+1, 3 and 5
are suitable for systems with more than two hard disk drives per disk group.
Caution!
● Do not configure RAID 0 and RAID 3 or 5 within the same group! Data loss
possible!
● Do not configure more than 2 TB -1 MB within one group! Expand capacity
will loose data, if you go beyond that barrier.
Number of disks per disk group Possible RAID levels

2 RAID 0, RAID 1
3 or more (max. 16) RAID 0, RAID 0/1, RAID 3, RAID 5
