    Solid business case for green IT practices

    As conventional energy sources dry up, the cost of electricity increases. Expanding energy usage is wreaking havoc on the environment, so businesses must find ways to become more energy efficient. Organizations of any size that spend heavily to power and cool their information technology (IT) operations can save money and help the planet by going green in IT. John Lamb, an IT architect, explains how to get that done in this informative, comprehensive and eminently practical book. He offers many helpful case studies of a wide variety of companies and nonprofits that have successfully made the transition to green IT. He presents a strong business case for environmentally sound IT, describes best practices and touches on some primary technical issues. getAbstract suggests Lamb's thoughtful guide to CEOs, chief information officers and other IT professionals. Executives of all kinds will be able to understand this book, though Lamb includes enough technical data to provide extra utility to IT experts who want to make their operations less costly and more sustainable.

    Great overview of the topic of Green IT with lots of examples and links

    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.

    Greeing of IT is a necessity & not just a niceity

    This easy to read & understand book is an eye opener for IT Professional and Organizations. After reading this I clearly understand the fact that, whereas Greening of IT gives avenues for saving money & saving the planet, it is also highlighting an important unavoidable situation of Power shortages in big cities in US and also the growing power shortages in developing countries where the majority of the IT growth is. Greening there is absolute necessity for survival & improved bottom line numbers.

    Better we adopt; save money & save the planet as well. Great Book.

    Great Book with many valuable insights in how companies can go green and improve the bottom line.

    This book provides information about the practical business benefits of going Green. The author has struck a very good balance between giving detailed information that a business can implement, and making the writing style approachable to normal people interested in the topic of how to build a Green America.
    I would recommend this book for anyone interested in finding out about all this "go-green stuff" and how it can impact your family, business, and world. You will quickly find that going green is really common sense. After reading the author's handling of this subject, you wonder why would you continue to do business and life the same old way.

    Dr. John Lamb has a Ph.D. in engineering science, which is quite

    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.”

    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.

    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.

    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!

    A must read for Executives

    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.
