I just grouped two broadcom nics on a standalone OI box. I could help you with the OI commands - basically, google open solaris dladm create-aggr - but I think you've got more pieces to fit together in the all-in-one setup, right? And did you set a corresponding port group on your switch? And are you testing with two clients running IOMeter or something? Whats network traffic look like in esxi using esxtop during an IO test?
Nice to know it's working. I'm not sure what you mean by port group.
I have 4 x NICs on a single vSwitch in ESXi. They're load balancing via IP Hash to a Cisco SG200 switch. So AFAIK, ESXi should have ~4Gbit/s throughput in the vSwitch out to my network. I just tried adding 2 x Intel E1000 vNICs to OI and it behaved strange.
Please correct me if I'm wrong, but that's how I think it works
