Kurzbeschreibung
How IT Can Drive Immense Business Value by "Going Green" * For CEOs, CIOs, CFOs, and IT leaders: The green IT business case and best practices for making it happen* Timely help for companies facing rising energy costs, new government rules, and growing public concern* Powerful new insights from IBM's breakthrough $1 billion green computing initiative Chances are your enterprise IT organization has a significant carbon footprint. In an era of unpredictable energy costs, reducing energy usage throughout your data centers and IT infrastructure represents a powerful cost-cutting opportunity. Now, a top green IT expert shows business and IT leaders how to drive powerful business value by improving IT's environmental performance. Drawing on leading-edge experience, John Lamb helps you realistically assess the business case for green IT, set priorities, and overcome the internal and external challenges to making it work. He offers proven solutions for issues ranging from organizational obstacles to executive motivation and discusses crucial issues ranging from utility rate incentives to metrics. Along the way, you'll discover energy-saving opportunities--from virtualization and consolidation to cloud and grid computing--and solutions that will improve business flexibility as they reduce environmental impact. Lamb presents case studies, checklists, and more--all the practical guidance you need to drive maximum bottom-line value from your green IT initiative.

Great overview of the benfits and challenges of greening IT
16. Juli 2009
Format:Taschenbuch
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.
