SSA RAID50

[andy_msc]

Hi,

is it possible to create a RAID50 array with 7, 11 or 13 hard drives?
SSA won't allow selection of RAID50, only RAID 0,5 and6.

Raid50 works with 6 or 10 hard drives.

it is not possible to create a RAID50 array with 13, 17, 19, 23 hard drives because it is not possible to divide them into several identical raid5 logical drive sets (parity groups).

This is explained in this document on page 17-19 (RAID 50, RAID 5, Parity groups)
