Well you could try BSD with XEN/AoE :)
I could but that alone isn't reason enough to get as heavily involved with BSD as I would need to be in order to make a go of it on production systems.
The more I read about ZFS the more convinced I become that it is on the right track. Put _all_ of the responsibility for data integrity in the file system where it belongs. Do _not_ spread the problem around in layers of obscure and difficult to maintain (read expensive and easily obsoleted) hardware and software layers.
MD and LVM in Linux have been free and unchanged (not obsoleted) for years. So I don't really see that as much of a problem. I agree about tossing out hardware RAID in favor of software though. But so far I'm not seeing any real killer feature of ZFS that makes me want to have it. Having separate LVM and MD and filesystem layers really isn't so onerous.
