[ TIP OF THE DAY ] Ways in vSphere to separate traffic from different networks.

There are 2 Ways in vSphere that you can separate traffic from different networks (ex. ESXi Management and vMotion) on the same ESXi Hosts. You can either create separate vSwitches using dedicated NICs or if NICs are not available you could also create separate port groups using different VLAN IDs on the same vSwitch. 

The following image shows you how 2 VMkernels port groups "MGMT & vMotion" go through different port groups with VLANs 10 & 20 in the same vSphere Standard Switch (vSS) 0.
