Can these raw devices > be based on top of DRBD? A running drbd device looks like a block device. Orrible or other DBs can open() that block device with O_DIRECT, which may or may not minimize caching effects, and may or may not improve performance. You'd have to try it and see. It might work. Take a look at "man 2 open" to see what that flag does. I would expect performance gains to be minimal, but that's just me.
