Mike Laverick from RTFM-ED.co.uk released a quick guide based on the Beta version handed out to the attendees at VMworld 2007 and added some updates from the Beta Programme he enrolled. The guide will also be available as appendix "B" in the book "VMware Infrastructure 3: Advanced Technical Design Guide and Advanced Operations Guide"
