Some hosts/OS can do load balancing between NICs. If a host has two

Don't do this.
Agreed
If the ports go to two different switches (that cannot do cross-chassis
etherchannel), use active/passive bundling, not load-sharing.
Just for completeness: under OSes like Linux, there are a few
weird/esoteric NIC load-balancing methods that *claim* to work - usually
where all the traffic comes in a single NIC, but is load-balanced out of
multiple NICs with the source MAC address of each egress NIC, not the
attached layer3 interface. I would avoid like the plague and stick to
active/passive.
