I hope this helps.

Thanks, the reason of not using ordinary disk rack, is the speed.
SAN Storage speed is much higher compared to ordinary disk speed
Example
making a tar backup on SAN Storage of 120GB takes 4 hours
making the same tar backup of regular disk take 16 hours
Then SAN Storage, has more data protection in case of power outage because of cache. So SAN Storage has more advantage.
So back to the question
Single Pseries with Two Fibre Card,
connect directly one HBA fibre card to Controller A
connect directly the other HBA fibre card to Controller B
I have not tried this yet, because I don't want Data correction, perhaps someone who has tried this can help me if it will work or not
