|I suggest using GB for networking. If available, use 1GB for management and kernel and a separate GB interface/uplink for VM data. That would be 2 vSwitches, at least one GB uplink each. |
You will not see a bottle neck for the vm data with a GB NIC. I have several deployments with 1 GB for vm data (non-kernel) and the physical computer count accessing the virtual servers is about 53 computers. here's no bottle neck .
1GB for storage and management will be enough too but if have the option in the GB switch to group interfaces together then do 2 to 4 interfaces as port group. You will need as many physical interfaces on the server. How big the port group depends on the number of interfaces you have.
The grass may not be greener on the other side but might have less weeds...
