Hello everyone! Quite a newbie in the ESXi 5.0 
I have configured two VSphere ESXi 5.0 servers with two network cards on each server, the first NIC acts as a virtual switch to the Internet, and the other NIC solely acts as the communication link (Heartbeat) between two VSphere Esxi 5.0 using crossover cable.
My question is, how can I create such switch in VSphere for the sake of communication between these 2 servers with a crossover cable? I would like to connect my VMs (CentOS 6) on each server via this network card with crossover cable for the purpose of heartbeat communication. I know how to create a normal vSwitch which can communicate with the Internet but I have no idea how to create a switch for those NICs connected with a crossover cable.
Please drop me a line if you know how. 
P.S. The whole idea of using crossover cable instead of using plain ethernet cable is that the crossover cable eliminates overhead and avoid missing packets because of the processing time of switch.
