Preparing an LSI SAS 2008 based controller for ZFS

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
