port groups (number of nics)

[beckhamk]

I understand that to vMotion a vm between esx hosts that the network configurations need to match (port groups/virtual switches).

I would like to know as long as the port groups and virtual switches match between all hosts, does it matter how many nics are assigned to a virtual switch for vMotion to work?

Example:

ESX host: Host1 - vSwitch2 with port groups A, B - has vmnic2, vmnic3

ESX host: Host2 - vSwitch2 with port groups A, B - has vmnic2, vmnic3, vmnic5

Will vmotion still work in this scenario. I am thinking as long as the port groups and vSwitches match, it doesnt care about the number of nics being used.

Thanks in advance!

You are correct. It doesn't matter if you don't have the same number of physical NICs assigned to a vSwitch for vMotion to work.

The requirement is that the label of the PortGroups must match.

A good practice is to match also the number of vSwithes (but it is not strictly required).
