The 1000v Deployment guide has a design suggestion at the end for ESX hosts with 6 physical Nics.  The suggestion is to create two vPC-HM port channels; one with two physical NICs assigned to it dedicated for VMware VMotion as well as the service con...

Hi,on the nexus i have the port-profiles "system-uplink" and "data-uplink".The "system-uplink" is only for traffic between the VSM and the VEM and needs only one NIC connection (better two for HA, right?)The "data-uplink" is for traffic between the n...
