HI! I've been playing with dual site openstack clouds. I use ceph as a backend for Cinder volumes. Each openstack has its own ceph cluster. Data replication is done by ceph rbd mirroring. Current Cinder replication design (cheesecake) only protects against storage failure. What about support for multi site deployments and protection of whole data center. Has any work been planned or done yet on that topic? Kemo
