You can run 2 drives on each controller, especially with raid 1, but you lose
some of the benefits. With mirroring, you could have the primary slave mirror
the secondary master and so on. That way if the primary slave goes down and
takes the primary master with it by locking up the channel, your array will
still function somewhat.
Not the best way, but it will work. Don't do raid5 this way.
