What EMC Data Domain BOOST & distributed segment processing can do to reduce the bandwidth usage. The picture shows the load on a 10G Ethernet link to a Data Domain before and after the enablement of Distributed Segment Processing.

The distributed segment processing is turned on by default from DD OS 4.8.
The graph show Mbits/sec but it is in GB/sec.
