In my last post I wrote about how the Adaptec 5805 RAID controller was the wrong choice for our backup server. So I started some research, based on the following criteria:
- Production quality driver (so no more crashes, hangs and other weird behavior)
- Pass-through support (/dev/passX), including S.M.A.R.T.
- JBOD support (disks should show up as devices /dev/daX)
- Decent throughput
- Existing success stories with ZFS
- Reasonable price and availability
