I'm in the process of setting up something similiar to yours. From the whitepapers, VMware seems to want you to dedicate nics for a lot of different functions, requiring a large amount of nics. I will have a single onboard for management and a dual Intel NIC. I was thinking 1 to attach to my HP VSA iSCSI SAN and 1 for Heartbeat/Vmotion, etc?
Is that your thoughts using 3 nics?
The whitepapers from VMware are for production environments, not for two-host lab setups. No way I'd set up a production cluster like I have in my home office. Right now I have both my onboard NICs in a single port-channel and just let it balance across. I set priority for vMotion to go over one, VM traffic over the other, etc...but they are in the same channel and will failover if needed.
You should have no problem.
