You could have a look at OpenStack Swift: it has geo-replication. Swift is an object store so it is not mountable like a block device (same functionality/api as the Rados gateway). Depending on the expected usage this could pose a problem... Another thing to take into account is that Swift is "eventually consistent" instead of strongly consistent. I think Ceph is working on something similar for the Rados gateway. Cheers, Robert van Leeuwen
