I am currently working on setting up a Windows Server 2008 cluster for SQL 2008. I have 5 hosts and would like to be able to use HA, DRS, and vMotion. With that said I will need a heartbeat between them. Unfortunately I don't have full control over the hardware because it is managed, if I did I would use a NIC on each into a VLAN for everything, that probably is not possible.
So with that said, I am looking for suggestions on how to get a network connection across all these systems for a heartbeat network.
