For example, you may want to use a separate vSwitch along with separate network cards for carrying DMZ traffic in a certain host. However, you may want to make sure certain types of traffic are physically separate from other types of traffic. This way, you don’t need a physical network cable connected for every single different network you want ESXi to interact with. Simply adding port groups with additional VLAN tags lets you use the same number of physical network adapters in your server. What are the use cases for each of these methods? Alternatively, if you have additional network adapters available, you can create a new vSwitch for VM traffic.


You can easily set up VM Networks on your first vSwitch by adding additional port groups.
