  You will find this a lot nicer if you have the backplane connected to a
RAID controller, particularly a Mylex controller supported by
"mlxcontrol".

  Hot swap support isn't really a factor since hot-swap support is only
useful in a RAID configuration, and the software RAID module, vinum
doesn't support hot-swapping drives.
