As part of the highly acclaimed Mastering series from Sybex, this book offers a comprehensive look at VMware vSphere 4, how to implement it, and how to make the most of what it offers.
- Shows administrators how to use VMware to realize significant savings in hardware costs while still providing adequate "servers" for their users
- Demonstrates how to partition a physical server into several virtual machines, reducing the overall server footprint within the operations center
- Explains how VMware subsumes a network to centralize and simplify its management, thus alleviating the effects of "virtual server sprawl"
Now that virtualization is a key cost-saving strategy, Mastering VMware vSphere 4 is the strategic guide you need to maximize the opportunities.
Scott Lowe has worked in IT for more than 15 years and currently works with a national VAR/reseller as a technical lead specializing in virtualization and virtualization technologies. Scott maintains a well-respected virtualization website, blog.scottlowe.org, and is a contributing author for SearchVMware.com and SearchServerVirtualization.com. Scott is also the recipient of a VMware vExpert Award, an honor awarded to a very select group of individuals for their contributions to the VMware and virtualization community in 2008.
This text is a well written introductory guide (meaning that although it covers some advanced topics, it is written with the beginner in mind), and although (as other reviewers have indicated) many will quickly outgrow this effort, Scott Lowe provides a great one-stop shop for getting going with vSphere 4. What the potential reader will need is highly dependent on how deeply they will get involved with the product (and technologies offered as part of the product). As a consultant architect, my reading was initially focused on the non-core portions of the book that concentrate on creating and managing virtual machines, migrating and importing virtual machines, and managing virtual machine resource allocation, although other portions of the book were later read as well. Combined with the introduction where vSphere 4 is explored and product editions and licensing are explained, this reviewer was able to begin discussing (with quick turnaround) the environment with fellow consultants and client staff after a reading of this text.
VMware documentation and white papers will need to be read in conjunction with this text once the basics are understood, although in some aspects the explanations provided in this book cannot be found elsewhere. While the bulk of the material found here is otherwise available from alternative sources, the organization that Lowe provides is superb. For example, Table 1.2 ("Overview of VMware vSphere Product Editions") is complete, listing all editions of vSphere and the options available with each, while the white paper ("VMware vSphere Pricing, Packaging and Licensing Overview") that Lowe notes at the bottom of the table, although a good reference, is fragmented in the opinion of this reviewer, and a search of the VMware website separates the edition comparison across dedicated pages for small and midsized businesses and large businesses.
One aspect of which the potential reader needs to be aware is the sparse coverage of automation in Chapter 14. Although vCenter Orchestrator, PowerCenter, PowerCLI, and ESX shell scripts are introduced, the coverage of these areas is very raw. And although the author correctly indicates that ESXi does not have a Linux-based Service Console that can be accessed, he limits his advice on porting the scripts that he shares to run within the vSphere Management Assistant (vMA). Lowe freely admits in the concluding pages of this chapter by writing that there is "much, much more to writing shell scripts than the tiny snippets I've shown you here", and anyone experienced in writing UNIX shell scripts should already know that entire books have been written on the subject. This reviewer especially appreciated closing "The Bottom Line" sections provided at the end of each chapter (and answers in Appendix A to questions intended to deepen skills and understanding by working out exercises). Well recommended to anyone needing an introduction to virtualization that is specific to VMware vSphere 4.
So, Should You Get This Book?
Newbie: For a VMware Newbie, this is a very good book. You're in for a proper initiation into the virtual world of computer resources. Still, you do need to work with the product otherwise your retention for the information presented will be very very short indeed.
Seasoned: Short path to upgrade your ESX 3.x knowledge to vSphere and see what's new in ESX 4.x. Once done, the possibilities are endless, or at least you can start reading the technical manuals for more details and specifics and the multitude of presentation, White & Technical papers and plenty of high quality training video on the net and You Tube.
Seeking VCP: The book will cut your study time in half; your will get all the essential information and a few valuable tips to get your nearly ready for the big day; but again you will have no choice but to scourge through the technical manuals and examine every screen in the product to get really really comfortable before attempting the VCP 4.x exams. There is no substitute to experience.
Attended ESX Course: From previous experience, ESX course are well laid and worth every penny spent.
No doubt, this is a good enjoyable book and quiet informative. I'm reluctant to say it's a "Mastering" as that stage of knowledge requires substantial commitment to work intensively with the product hand in hand with the technical manuals before you can say you have mastered the product; but it's a tool for mastering the product.
A quick note, you will outgrow this book quickly, so you may not end up keeping it as a reference; the products technical guides from VMware are 2nd to none in their quality.
Another interesting point, between me and my colleagues in the office we purchased about 5 copies of this book; we all loved it.
If I had to add something for improvement it would be more samples of basic things like a VM build for a SQL Server from start to finish using the new vSphere 4 features. Disk setup, type, adapters, etc...
All in all this a great book that i can highly recommend. Not only is it very informative but it is also easy to read. I hope he creates more like on using the included backup, or 3rd party tools, or situational like what to do if a host isn't responding but the VMs are still running fine.
A great read!
