Hi Michael, Thanks for your comment. Nexus 1000V has addressed specific needs of many of our customers requiring segmentation (VSG) and Cisco Nexus OS features across multiple hypervisors and orchestration platforms. Also, we recently introduced Application Centric Infrastructure and as part of that we introduced Application Virtual Switch. AVS is managed directly from the APIC (ACI controller) and hence ACI offers full end-to-end visibility, local switching/forwarding and policy enforcement at the hypervisor level. In our view, you need to consider Cisco's physical + virtual with heterogenous hypervisor support compared to primarily VMware centric NSX solution. You should visit http://www.cisco.com/go/aci for more information about offering.

Thanks again for taking time to read our article and hoping you agree with the primary premise that we need open choice in hypervisor vSwitching offerings and hence choice in DC/cloud solutions.
