Connecting 3 ESXI hosts for High Speed Networking

Hi There.

I've been debating between Infiniband, and 10G Ethernet. I know that I can connect my 3 hosts together for vMotion and vSan over infiniband without a switch. Is it possible to do the same thing with 10g Ethernet? I'm looking at at some point getting an LB6m or some other 10g switch when they come down in price, but right now they are prohibitively expensive for me. 3 cards and 6 twinax's (I'm expecting I would need dual port cards) wouldn't be an issue since I'd have to get them anyway. It would be nice to be able to have stop gap measure, even if it means that it's not the most optimal setup.

You don't need a subnet manager for Ethernet. Just connect the NICs together and assign IPs on three different subnetworks otherwise you will have routing issues.

Host A/eth01 - Net 01 - Host B/eth01
Host A/eth02 - Net 02 - Host C/eth01
Host B/eth02 - Net 03 - Host C/eth02
