How to setup virtual networking when 8 pNICs are involved follows:

pNIC0 -> vSwitch0 -> Portgroup0 (service console)
pNIC1 -> vSwitch0 -> Portgroup0 (service console)
pNIC2 -> vSwitch1 -> Portgroup1 (VMotion)
pNIC3 -> vSwitch1 -> Portgroup1 (VMotion)
pNIC4 -> vSwitch2 -> Portgroup2 (Storage Network)
pNIC5 -> vSwitch2 -> Portgroup2 (Storage Network)
pNIC6 -> vSwitch3 -> Portgroup3 (VM Network)
pNIC7 -> vSwitch3 -> Portgroup3 (VM Network)

How to setup virtual networking when 6 pNICs are involved follows:

pNIC0 -> vSwitch0 -> Portgroup0 (service console)
pNIC1 -> vSwitch0 -> Portgroup1 (VMotion)
pNIC2 -> vSwitch1 -> Portgroup2 (Storage Network)
pNIC3 -> vSwitch1 -> Portgroup2 (Storage Network)
pNIC4 -> vSwitch2 -> Portgroup3 (VM Network)
pNIC5 -> vSwitch2 -> Portgroup3 (VM Network)

How to setup virtual networking when 5 pNICs are involved follows:

pNIC0 -> vSwitch0 -> Portgroup0 (service console)
pNIC1 -> vSwitch0 -> Portgroup1 (VMotion)
pNIC2 -> vSwitch0 -> Portgroup2 (Storage Network)
pNIC3 -> vSwitch1 -> Portgroup3 (VM Network)
pNIC4 -> vSwitch1 -> Portgroup3 (VM Network)

How to setup virtual networking when 4 pNICs are involved follows:

pNIC0 -> vSwitch0 -> Portgroup0 (service console)
…………….. -> Portgroup1 (VMotion)
pNIC1 -> vSwitch0 -> Portgroup2 (Storage Network)
pNIC2 -> vSwitch1 -> Portgroup3 (VM Network)
pNIC3 -> vSwitch1 -> Portgroup3 (VM Network)

How to setup virtual networking when 3 pNICs are involved follows:

pNIC0 -> vSwitch0 -> Portgroup0 (service console)
..................-> Portgroup1 (VMotion)
pNIC1 -> vSwitch0 -> Portgroup2 (Storage Network)
pNIC2 -> vSwitch0 -> Portgroup3 (VM Network)

The best way to use 2 pNICs is as follows:

pNIC0 -> vSwitch0 -> Portgroup0 (service console)
..................-> Portgroup1 (VMotion)
..................-> Portgroup2 (Storage Network)
pNIC1 -> vSwitch0 -> Portgroup3 (VM Network)
