Description
As I understand it, in Ceph one can cluster storage nodes, but otherwise every node is essentially identical.
This is not true in a distributed data center. Or even in a multi-rack situation.
I want to prefer accessing nodes which are "local".
The client in rack A should prefer to read from the storage nodes that are also in rack A.
Ditto for rack B.
Ditto for s/rack/data center/.
As far as I understand, the Ceph clients (I care less about efficient internal communication) can't do that.
However, I think this would be an important feature for many high-reliability situations.
