Abstract:
A cost function is determined for assigning first deduplicating storage units of a first storage system for replication onto second deduplicating storage units of a second storage system. One or more of the first storage units in the first storage system are assigned to one or more of the second storage units in the second storage system based on a minimized cost resulting from the cost function.
