HP ML350/370 G6 Expansion Drive Cage Installation problem

Posted in Geekery, Work on November 5th, 2011

So, you’ve just bought the expansion drive cage (8 more SFF drives! W00t!) and you’ve got the SAS RAID controller Expansion Card as well. Great! Only one problem – HP forgot to include a crucial bit of information regarding how you wire the damn thing in.

Step 1: remove the existing SAS cables from the existing drive cage and motherboard. Discard these short cables.

Step 2: Take the shorter pair of cables from the expansion card kit, and route them from the SAS ports on the motherboard to ports 8 and 9 on the card. Then proceed with running the remaining cables from the two drive cages to ports 2-5 of the card.

The instructions that came with my kit left these two steps out, and I wasted about an hour trying to figure out what I did wrong (Whaddya mean there’s no new drives in the ACU?). Finally found an article with pictures in the HP site, but they could have saved me the trouble by just printing the above two lines in the kit.

How’d the rest of it go? Rather smashing, actually. That server now has 60GB (!!) of RAM and another 900GB of RAID5 storage.
