Hi Goeff, there are many things that you can do, depending on what you want.
However, I would not be so concerned about an adapter failing, failing disks are much more common. Here are some things to do/consider: 1. put each adapter on a separate PCI bus. 2. balance the disks over the adapters. 3. if you really don't care if a disk fails, use RAID 0, if the system can't go down use RAID 5. 4. Lately I have been using hardware RAID and LVM striping, the reliability and performance is very good. 5. If you are putting you TSM DB and LOG on these disks: I might not use any kinda of striping: JBOD or RAID 1, is probably better. Using TSM mirroring across SSA adapter is probably best too. 6. if your using filesystems on these disks, use RAID and LVM striping.

I'd like any opinions as to best connect this. What I've got is an M80 with 2 SSA controllers, and now, 2 SSA drawers full of 36gb disks. What would be the best way to connect this so no matter what happens to the controllers all the disk would still be available? Is there a different solution I should use? Thanks for the help.
