That is correct, DreamObjects is currently in one data center. Data is still replicated three times throughout the cluster and we will not return SUCCESS until all copies are written, er… successfully.
We’ve heard that a singe data center is a concern for some customers and we’re investigating that now. It’s primarily an implementation detail in Ceph that is not fully resolved. For customers that do not view a single data center as an issue for them, we are working to provide the best service and value we can.
