I advocate taking it further with clustered filesystems on inexpensive nodes. Good design of those can solve problems on this side plus system-level. Probably also need inexpensive, commodity knockoffs of things like Stratus and NonStop. Where reliability tops speed, could use high-end embedded stuff like Freescale's to keep the nodes cheap. Some of them support lock-step, too.

GlusterFS now supports its own (out of band) checksumming. So you could have a Btrfs brick, and an XFS brick to hedge your fs bets. And also setup glusterfs volumes to favor XFS for things like VM images and databases, and Btrfs to favor everything else.
