        Depends. RAID5 has worst right performance, so it might
be bad for something like mail. Generally I use RAID0+1 for mail and RAID5 for
web data.

        Also, depending on your budget and/or concerns about
failure/downtime, you might want to vinum mirror the entire base system disks.
Be sure to have the root partition vinumed also. There is good documentation
in the handbook and on gregs page.

        Actually all my nfs servers are "diskless" except for the
data and boot off of boot servers using PXE. The boot servers have
vinumed system disks.
