  • We (Dell)are pursuing a three pronged approach for SDN. They areNetwork Virtualization Overlay (NVO) - Vmware and Microsoft are driving it from the hypervisor with VXLAN & NVGRE. Vmware bought Nicira to strengthen their position in this technology. We are partnering with them to offer a complete solution. We will complement their solution with NVO gateways (gateways are needed to talk to legacy networks and physical servers). Initially, it will be an x-86 based appliance for NVO gateway and over time a switch based NVO gateway.OpenFlow based network virtualization for customers wanting end-2-end (physical or virtual+physical switch) SDN solution. These are likely to be greenfield or cloud customers.Here, we are partnering with BigSwitch as the primary OF controller vendor. We have also started to partner with others like NTT Data. Our OF enabled switches work with any OF 1.0 compliant controllers – they include many open source controllers like Floodlight. We have shown our solution working with Openstack cloud orchestration at Interop 2012.If customers want to continue to deploy legacy (traditional) switches, we offerbetter manageability of traditional switches (with Open Automation capabilities like bare metal provisioning, Smart scripting, programmatic management, virtual server networking etc). We realize that many customers have Cisco switches in their network – hence, we offer excellent inter-op with Cisco switches/networks with Cisco like CLI and highly inter-operable spanning tree protocols.We at Dell are not biased towards any one approach – we don’t have a technology religion.  Other vendors like Cisco are biased.
