I don´t recommend to do a port-channel with ESXi Servers.
I am driving 14 ESXi Servers with each 4 10Gig LAN-Ports. I tried with port-channels (aggregates), but it messed up (with Cisco classic (as Cisco Nexus) and Meraki). I do not use LACP in this case. And it´s working. ESX puts the traffic in the right way on the network ports for it´s own (round robin).
