vSphere 5 is getting thrown around at the VMware support forum, even on the unrelated easy questions. Looks like it’s about to leave beta. Could it be that the well respected guy that answered the question is participating in the vSphere 5 beta?
I read another post not from VMTN about a person using the beta and he talked about a couple of the vCenter new features. Guess he didn’t care too much about the nondisclosure agreement.
