I have difficulty understanding NICs and Switches in VMware.
At client's sites I often see more than one NIC connected to a single virtual switch.  These are then connected to one single physical switch.

In the physical world, I would at worst expect this to give you a signal loop and at best no gain, as spanning tree would prevent worse from happening.  That is unless you actually configure your switches to use multiple links as a trunk.

I am not aware that this can be done with virtual switches.  So:  What is the use of connecting more than one NIC to the same (let's assume) unmanaged switch?
