I reconfigured them to use geom mirror instead, and everything has

the mirror all by itself.
We have some DL160s with the same B110i controller running as Linux KVM
host machines, and like you, told the controller to treat the disks as
basic drives and use the OS to manage the mirror (in our case using
mdraid, but the principle is the same).
Agree that these pseudo-raid cards are not worth the time of day.
Incidentally, we also did some testing with some Dell PE2950s a while
back (with 'proper' battery-backed hardware RAID controllers), and still
ended up with considerably better performance by telling the controllers
to treat the disks as just disks, then using mdraid in the OS. Also has
the advantage that in the event of hardware failure, you can move the
drives to any other system and still access the data - something that's
not always an option if you're relying on a proprietary RAID layout.
Kind regards,
Chris
