How about one large raid, and two partitions to serve each purpose?
Being so limited in HW, youre either going to take a _huuuuuge_ performance hit with only 2 disks per raid (unless Raid0), or an availability hit with everything on one RAID set. But..considering the costs of adding RAID to a server..take a peek here for a high(er) perfomance RAID solution..if Fbsd had an iscsi layer like linux has had for...5yrs or so..this would be a slam dunk as you can still serve it as block data. If that cant help you, it might help the next guy with only a few K's to spend on large disks and raid controllers. On 1/25/07, Milo Hyson <[EMAIL PROTECTED]> wrote:

Unfortunately, I'm a bit limited in terms of equipment and application requirements. For starters, the app specs currently call for two arrays: one for general file-serving and databases, and the other for backups. Due to limited hardware I'm to run both on the same controller. Far from ideal, I know, but it's what I have. Second, I need to keep at least one drive as a hot-spare. Thus, I have seven drives that I somehow need to partition into two groups and maximize performance without sacrificing reliability. Lastly, the RAID controller does not permit more than two drives in a RAID-1 set.
