VSA Cluster Network - Using EtherChannel / Link aggregation

I understand all the hosts in the VSA cluster must have two dual-port or four single-port network interface cards for the VSA network configuration.

Is it possible to have EtherChannel / Link aggregation enabled for VSA?

e.g. Dl 380 G7 comes with 2 dual port and if I add one additional 4 port gigabit card - i have total of 8 ports

2G - VM network + ESXi management network

2G - VSA front end network

2G - VSA back end network

2G - vMotion, HA (ESXi feature network)

Let me know if thats possible, if so, how to enable it

Cheers
