Format: Paperback
An informative and well written book that elaborates, illustrates and emphasizes with right amount of contrast. John has exhibited a real understanding of the challenges and leads to practical solutions while training your mind to reflexively think about the impacts that your technology decisions would have on the environment. Book is well organized and a treat to read distinguishing itself from other books available on the topic.

A must read for Executives and IT Professional to recognize monitory benefits while saving the planet.

Great overview of the benfits and challenges of greening IT July 16 2009
By Robert R. White - Published on Amazon.com
Format: Paperback
Great book with real world case studies to reinforce the importance of the "Greening of IT".

It was easy to compare the thinking of current IT infrastructure to where IT infrastructure needs to go as there were plenty of tables or web links to illustrate the efficiencies gained using a greener approach. The main drawback to using external links is that they may not be available by the time the book is published. A website with updates would be a good idea - the free online edition is only a 45 day trial.

Some of the newer technologies made it into the book, but I did not see some of the others - for example Flywheel UPS (although flywheels have been around a long time). Fuel Cell backup power did rate a mention as an emerging technology.

Some more discussion on Computer Room efficiencies and the maximum limits of under floor cooling to handle the newer high density racks based on air flow limits would have been a good addition. This is certainly not a negative because there is only so much that you can cover in a general book.

A few illustrations were a little too small or did not have enough contrast for easy viewing in a black and white publication (example Fig. 11.3, and 11.4 which is a thermal camera image and better suited to color), but did not detract from the material being presented. I am assuming the choice of black and white was driven by the desire for a Kindle version, as well as the extra printing costs needed for color.

As mentioned a lot of external links to extra information were provided, and overall a great snapshot of the current thinking related to the Greening of IT. Naturally with the author being an IBM person there was good coverage of IBM technologies - but there was more than enough coverage of non-IBM solutions so this was not a problem. I recommend this book for both the technical and non-technical reader as the material worked at both levels.

This is not a theoretical book for anyone dealing with high energy costs, it is a must-read to put a team in place to Go Green! April 3 2012
By Clea Zolotow - Published on Amazon.com
Format: Paperback
Dr. John Lamb has a Ph.D. in engineering science, which is quite apparent in
reading his book, "The Greening of IT." This book provides a welcome relief from the
many books that center around virtualization as the panacea for energy utilization. While
"The Greening of IT" does have virtualization as one of the steps required for lowering
energy utilization, it takes an engineering approach. He says, "This book provides details
on the importance of implementing green IT....and especially the case studies for
`lessons learned' and the best practice approaches for implementing green IT."
Dr. Lamb provides a global view of Green IT. This is appreciated as he puts
Green IT in a world-wide perspective, detailing why we need to save energy. The global
view of Green IT continues by placing it squarely in the roadmap for "reducing
greenhouse gases which, in turn, can help reduce global warming," a goal for both the
United Nations (UN) as well as the White House.

Throughout the book are sprinkled engineering explanations such as the
difference between volts, watt, amps, KWHs and voltage levels. As another example, Dr.
Lamb's explanation of "Data Center Cooling Basics" clarifies HVAC systems, the
cooling equipment, and new technology (such as stored cooling, thermal storage systems,
and phase change materials.

Dr. Lamb uses IBM's 5-step program for datacenter efficiency: diagnose,
manage and measure, use energy-efficient cooling, virtualize, and build new or upgrade
facilities when feasible.

Then there are two sections which I have not found in other books: (1) tuning
your applications to require less CPU and (2) Greening your laptop. Tuning applications
often does not happen as we virtualize applications and consolidate them rather than
looking inside the application to use less CPU. Many applications can be tuned to use
25% less hardware then today, however, requires time as the original application
developer is usually not still employed by the corporation. Greening our laptops is a
good idea as well and is a great step to helping use less energy. Dr. Lamb gives the
instructions in his book for Power Management Features and provides the option of
utilizing a thin client PC for corporations as well. (Maybe PROFS will come back, the
original thin client application by IBM, known either as Professional Office System or
PF Keys Rigidly On Freakish Settings).

Dr. Lamb's section on collaboration is interesting as it discusses the need for IT
vendors to "integrat(e) their hardware, software, and services" to help customers improve
their energy initiatives. Further, there is a good overview of IBM's energy monitoring
programs as well. The part where Dr. Lamb allows himself to go back to more
engineering-related topics where is really interesting. The chapter on "The Magic of
`Incentive' -- The Role of Electric Utilities" and "PG&E Lead Utility Energy Efficiency
Coalition" of the impact of energy companies on the Greening of IT and available
incentive programs. This type of explanation, looking outside the typical datacenter and
to the energy companies, was new to me.

The section on virtualization is made more interesting by the SPEC metrics for
virtual servers. Note that older frame's utilization is not tied to their power consumption.
Newer, greener frames use more power as the utilization rises. What is not covered here,
however, is the re-platforming of servers from, for example, a system p environment to a
system z environment. IBM Enterprise Computing Model (ECM) has re-platformed
hundreds of pSeries LPARs into a z/Linux box and reduced all costs as well as lowered
energy utilization. Maybe Dr. Lamb will put that in his next book.
In all, the 5-step approach for an "Energy Efficient Data Center" - Diagnose,
Build, Virtualize, Manage and Measure, and Cool - provides corporations a look at their
datacenter energy costs and find ways to improve their energy utilization and their
virtualization penetration. The emphasis on measurement throughout the book is very
important as Dr. Lamb provides methodologies for baselining (what to baseline) as well
as energy-measurement tools. The book ends with appendices and checklists to actually
do this work. This is not a theoretical book for anyone dealing with high energy costs, it
is a must-read to put a team in place to Go Green!

Format: Paperback
This book the greening of IT is well written and presented for both the expert as well as the beginner. The case studies are all well written given a real world scenario of how IT greening is taking place , A lot of informative data and links are given which will provide further reference for the IT professional.

A terrific book for both general readers and specialists June 21 2009
By Mimi Garel (married name) - Published on Amazon.com
Format: Paperback
As a university professor in humanities who is worried about the future and eager to get a glimpse into the present, I found John Lamb's The Greening of IT clearly organized, eminently readable and up-to-the-minute interesting. Especially persuasive is the author's analysis of how major global institutions and corporations--built for a pre-IT era--must remake themselves both to prosper in a new world of IT and to preserve and heal our old world! For those whose technical knowledge is minimal, Dr. Lamb presents a helpful introduction and excellent definitions and descriptions of process. For specialists, his explanations of engineering and economic strategies, as well as his richly referenced notes and practical or personal illustrations of problem-solving, are a great boon: it's all here. What I like best is Dr. Lamb's balance between the massive challenge we all face and the variety of solutions our species (not just the scientists and engineers) must implement. We can all make the incremental changes that will save us. Highly recommended!
