Jeff,

Good, this was the exact response that I was hoping for, as I've been told to
convince Adaptec to drop the binary RAID drivers in favor of helping out dmraid
development instead. That process will probably be difficult, but at least I
now have incontrovertible proof that nobody will bend over backwards to support
them and that dmraid is the way to go. Not that I'm terribly surprised by this.

It's good that there is a push to get non-binary-module support for these controllers in Linux. It's a shame that this is only happening now though.

It does rather suck that IBM changed to use this AIC79xx controller with "HostRAID" in the x346, x236, etc. servers. The last generation of servers (x235, x345) used an LSI Logic MPT Fusion controller which could do RAID 1 in hardware (or at least firmware) without a special driver - this sufficed for certain applications. With the new machines, RAID on the onboard controller requires using the stupid binary module which is only built against certain specific kernels, or using pure software RAID..
