At my (soon-to-be-last) company, emarsys, Linbit maintained our production clusters. We had a couple of Postgres servers and main file storage replicated across physical locations - a customer requirement, actually, that the system be capable of handling something like a fire at one of the data centers. Overall, it worked well. In the 2.5 years I was there, the only time I needed a backup was to restore my own mistake. :) I'd check it out if you're looking for a more complete replication system (Again, not RAID.)
