Re: LACP or no LACP, that is the question

LACP is supported only by the VDS 5.1 (vSphere distributed switch). Otherwise, you'll need to use an EtherChannel (mode on) set to IP Hash.

I typically don't bother with a port channel to vSphere Hosts unless there is a specific workload that would benefit. Normally I leave the ports as trunks and set the vSphere teaming policy to "route based on physical NIC load" (assuming VDS) or "virtual port ID" (assuming no VDS).
