For what it's worth, I'm doing exactly what you're looking to do right now with a whopping 7 DRBD devices. My write performance stinks - I can only sync at 4MB/sec before a CPU core becomes entirely busy in IO wait - but I suspect that's due to some misconfiguration, and haven't had much time to look into it. Other than the write performance, using DRBD and xen with heartbeat is really, really cool.
