Re: RAID5 (6502) on a model 400 question

Carl,

>Can I use the 6502 card in this AS400?

I have a 9402-40S, which is very close cousin to the 9402-400.  From what I was
told back when I did it, the 4 DASD slots on in the base tower are driven
directly by the MFIOP.  You can mirror one or two sets among the those 4 drives.
The MFIOP does not support RAID.

The 6502 can only be installed in a 7117 expansion chasis.  I installed my own
off parts obtained via eBay.  I have four 6606's off the MFIOP in two mirrored
pairs.  And a full set of eight 6606's in the 7117 expansion which are using
RAID off a 6502 card.

Without the expansion, the best you can do is four 6607's in two mirrored pairs
off the MFIOP, so you'd have roughtly 8GB protected.

The good news is the price of a 7117 has gotten real cheap on eBay (or even a
machine from which to rob a 7117 to bolt onto your 400).
