I've not done much with gluster, but I know people who have it in production and are happy with it. Sheepdog looks very promising - we've had a bit of a play with it and plan to do more investigation in the future... We have drbd in production and are happy with it. Over the years, I've had so much trouble with hardware RAID, that I now avoid it if at all possible. My experience with real top-end hardware has been that you get to find lots of interesting new bugs (both software and hardware) because you're using relatively unusual hardware - you end up with a machine which is like 0.01% of the global machines running Linux instead of 5% or whatever. When you do hit such bugs, often the developers can't reproduce the issue because they don't have access to the same hardware...
