Not only was HP an early mover in software defined networking, it's the top dog in the space. That's according to HP Enterprise Group chief Dave Donatelli, who points to the comprehensiveness of HP's SDN portfolio as something no other vendor currently has in-house. "We have the only complete solution available in the marketplace today," Donatelli told CRN in January. Our SDN happens to cover people all the way from the edge to the campus to the core. It's a complete solution consisting of OpenFlow technology supported on our switches; an HP SDN controller; and open APIs in our networking solutions that enables customers to develop their own apps and their own networking configuration as they desire. No one else has that across all three elements today." At this stage of the SDN market, HP may in fact have the most well-baked strategy. But it's still early days, and declaring leadership at this stage doesn't carry much weight.
