Why would you post about freebsd on opensolaris' list is beyond me.
Regarding your options with the ZFS pool, you will want to set your
disks as JBOD, so you can aggregate them with ZFS and use its native
features (including the self healing).
If you setup a hardware RAID then create a ZFS pool off it, you'll miss
on the self healing because ZFS will not see the individual drives.
Regarding your RAM needs, you are providing too few information for an
What will you use the server for ?
Regarding the H800 card on freebsd, I would test it beforehand if I were
you, there were problems getting the H200 working on 8.2 before.
