Can a RAID 5 be used on a M1015?
RAID 5 and 50 I found are to be avoided on the M1015/LSI9240 as the LSISAS2008 is absolutely terrible at XOR (parity bit) processing. To use this in a server get a IBM M5015/LSI9260 based controller.
How many disks are needed for a RAID 0 array?
Hot spares can be used as well. This is a RAID 0 array striped across RAID 6 elements, making it require at least 8 disks (2 sets of 4 disks) at minimum. It offers great reliabilty, but at a heavy cost in terms of usable capacity as percent of overall disk capacity.
