Keeps it simple in the beginning and works up to the more abstract concepts. Makes VMware very understandable for the novice.

VMware Cookbook: A Real-World Guide to Effective VMware Use
$39.99
As someone who works with VMware most everyday, I'm always on the lookout for new tips, ideas and things that make administration easier.

VMware Cookbook is organized into seven chapters that cover everything from installation to automation and much in between. The authors do a great job of explaining the nuts and bolts of core VMware functions in very understandable terms. The resource management and automation chapters were particularly useful and apply to tasks I come across frequently.

This is not a book that offers a broad reference - and doesn't claim to be; rather it offers VMware admins many, many useful tips, configuration options and excellent ways to fine-tune your systems. If you're looking beyond the basics of virutalization with VMware and want to get a better understanding of specific areas and learn more about optimizing and monitoring ESX, this is an excellent resource for you.

Mastering VMware Infrastructure 3
$59.99
I am certifying in both VMWare and XenServer, so I have been "book heavy." The technical material in this book, once you get to it, is good, but the writing is poor, chatty, maybe OK for a chat in front of a few friends. The author tries to be funny and conversational, but I strongly doubt that anyone buying this book is interested in being chatted up. I am poorer for my choice, but I will try the V4 book, mostly because it is by a different author.

VCP Exam Cram: VMware Certified Professional
$44.99
I would not recommend this book as it doesn't cover enough material to pass the VCP exam.
