Going back to the LSI website to check if these 9750 have an option to link their caches into one...

I was curious, *all* the LSI sAS RAID cards say 'single controller multipathing', both the megaraid cards and the 3ware cards (I'm setting up a server that has a 9260-8i now). I looked at their optional software, and none of it implements any sort of multi-controller failover.

If you have split or multiple storage backplanes/enclosures, I"d split the disks between the two cards, and multipath between each controller and its respective disks. this will take another set of SAS cables, of course
