Now that I think about my last post, I don't think that is right for ESXi. ESXi doesn't have a console port, right? So with 4 physical NIC ports, it might look like this:
pNIC0 -> vSwitch0 -> Portgroup0 (VMotion)
pNIC1 -> vSwitch0 -> Portgroup1 (Storage Network)
pNIC2 -> vSwitch1 -> Portgroup2 (VM Network)
pNIC3 -> vSwitch1 -> Portgroup2 (VM Network)
