I know the PERC H200 can be flashed with IT firmware, making it in
effect a "dumb" HBA perfect for ZFS usage. Perhaps the H800 has the
same? (If not, can you get the machine configured with a H200?)
If that's not an option, I think Option 2 will work. My first ZFS
server ran on a PERC 5/i, and I was forced to make 8 single-drive RAID
0s in the PERC Option ROM, but Solaris did not seem to mind that.
