I was looking at something like
http://cgi.ebay.com/New-32-Pin-SAS-...ltDomain_0&hash=item3a64e18de4#ht_2454wt_1139
To attach the cage directly to the P400 card. I don't have one of these servers yet but wanted to do RAID 5 when I get one.
I don't know about that cable, I'm not sure if anyone has taken the cables out of the back of the hdd cage in one of these yet. If they're just sata cables I don't know why that wouldn't work.
That would work, but you would lose the easy-swap capability of the drive chassis.
I took the backplane out to examine how the connectors worked, and they are special Amphenol branded connectors that screw on to the backplane.
Oh... and if you used the cable in your link, you'd lose the power cabling. So you'd want something like this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120683592163&ssPageName=STRK:MEWNX:IT
But it's unclear as to whether these connectors would fit through the holes in the backplane where the current ones sit. (Same for the ones you linked to).
I wish I'd taken some photos when I disassembled it now - it'd be much clearer to explain.
