Les,
That's pretty much my problem. I was hoping to kill two birds with one stone here. First order of business is to replace the single drive with a raid array. Second order was to replace a single iscsi server with duo of machines. If one machine had some sort of non-recoverable problem, the other could pick-up the torch and carry on, even if that means I need to "flip a switch" to make it happen.

But, I think the OP's real problem is that everything is tied to one single large drive (i.e. the software mirroring is mostly irrelevant as well as the controller type). These would get you a queue of outstanding commands compared to a SATA, but if you want a big difference in throughput or less latency when multitasking you really have to split things over a bunch of drives, either with some other type of raid or explicitly mounting different filesystems so you can control which things compete for the disk head position.
