Good stuff, a little outdated in parts
19 Feb 2012
Format:Paperback
I was kinda surprised that this was released in September 2011. It seems like it was not updated to include changes in vSphere 5.0 (released for beta in summer of 2011) or even vSphere 4.1 (released in summer of 2010). Specifically, some of the changes to CPU scheduling that have loosened the limitation on single vCPU VMs. Many applications released in the last two years will perform very poorly if placed in a single vCPU VM. Even some roles of Server 2008 struggle with a single core.
The author also goes off on "large single array" SAN configurations. The problem he is discussing (insufficient IOP capabilities) is very real but his blaming it all on single large array configurations is a false conclusion. It's ironic that a "virtualization expert" doesn't see the benefits of storage virtualization, or the waste in traditional array configurations that he seems to prefere. The real issue is people not evaluating their IO needs and purchasing insufficient hardware to meet those needs and growth. More dedicated array configurations have their place in very high IO applications, but to paint "large single array" configurations as a problem is inaccurate and is an argument I usually here from old SAN administrators afraid of losing their jobs.
Overall, this book is mostly a condensed version of the recommendations that VMware makes in their various vSphere documentation manuals and best practice white papers. I could see this book definitely having value to an administrator new to virtualization, but that administrator also needs to do some additional research to get more up to date information.

A must read for any VMware installations
26 Oct 2011
Format:Paperback
Let me start off by saying that this book has opened my eyes to VMware. I work for a corporation that has VMware implemented in the organization, and I can tell you that the corporation would have spent less money and time if only we had read this book sooner. Don't let the size of this book full you. It is jam packed with in the field knowledge of what not to do and why! It is an easy read, not like picking up a stereo installation guide. When you read this, you actually can feel the presence of the author in the real world experience scenarios and can relate. Like I said a must read, well worth the price for the book in the time and savings you will achieve.

Essential book for any VMware admin
26 April 2012
Format:Paperback|Amazon Verified Purchase
I purchased this book after reading various reviews, and I have to say I am very happy with my decision. This book covered a lot of key pieces you don't find in your normal administrator guides. I highly recommend anyone who is serious about virtualization and VMware to add this book to your tool-set. My background is 25 years of IT and working with customers and various different environments which also involved deploying and supporting VMware environments. Larry has a lot of gems hidden in this book people need to know to complete a successful deployment but also support it.
