I was waiting for these to come in they have arrived, and I think that you all could benefit from these presentations.
vSphere, What's New? - Technical Overview - Ofir Zamir (Team Leader SEs, VMware Israel)
and
vSphere Upgrade and Best Practices - Ben Hagai (VMUG Leader) and Yaniv Weinberg (
Senior Consultant at VMware)
Good presentation from all three of them. Enjoy!
