During the last VMworld in San Francisco I was lucky to receive a preview copy of this book.
And to take away the suspense, I still stand by my first impression of this book. A huge collection of all kinds of vSphere related facts, procedures and best practices.
If you're a vSphere admin and you have some questions, better first consult this booklet. Chances are you will find your answer in here.
The authors (Thomas, Duncan, Dave, Stuart and Bernie) are all well-know contributors in the lively vSphere community.
It will be like having one (or more) of them at your side during your daily vSphere administration tasks.
And to top it of, the book is crammed with practical PowerCLI scripts from none other than Alan Renouf.
This book will rapidly become one of your most consulted tomes.
In fact, better get two copies, one at work and one at home ;-)
