He points out that the IT/data centre space typically requires one engineer for 10,000 commodity servers while the carrier space currently requires one engineer for 10 servers or appliances. Even if carriers don't get to the 1000x improvement that these numbers imply, NFV's impact on OPEX will be profound.
