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
