ESXi 5.1 update 2
CPU: 2 sockets, 2 cores per socket
Memory: 8GB (memory usage is at 15 out of 32 GB )
HD: 200 GB thin provisioned
I've tried 1 interface and 3 interface.
One thing I've noticed is that the wizard spends a lot of time on the 'checking cluster name' step - don't know if this is normal or not. I'm using a simple cluster name of 'den'.
