domain. Pam Isom of IBM Global Business Services and lead in the
Intelligent Enterprise Archi-tecture project, was especially helpful in
her review of how IT architecture impacts green IT. The following
IBMers contributed to Chapter 6, “A Most-Significant Step—
“Virtualizing” Your IT Systems,” on virtualization: Mike Ebbers, Alvin
Galea, Michael Schaefer, and Marc Tu Duy Khiem of the IBM team who
wrote the IBM Redpaper “The Green Data Center: Steps for the
Journey,” and Bob Fagan of IBM Boulder who contributed to the
VMotion figures and description.
One interesting aspect of green IT is the universal interest among
diverse groups of people. Almost everyone is interested in green projects
and almost everyone uses a PC with connection to the Internet.
Therefore, we see the universal appeal of green IT. I would like to thank
all my contacts on this book for their valuable dialogue and suggestions.
Several people helped with the case studies in Chapters 9, 10, and 11.
Serkan Sahin of IBM Turkey provided information on the energy-
efficiency initiatives for a large data center in Istanbul. Alan Crosswell,
associate vice president and chief technologist for Columbia University’s
ptg
Information Technology, along with his Columbia IT colleagues Victoria
Hamilton, Lynn Rohrs, and David Millman, provided excellent case
study analyses for Columbia University’s Green Data Center initiative.
Columbia University made for an interesting and important case study
for green IT. Not only did the Columbia University case study bring up
many of the unique green IT issues within a large research university
(for example, each research project likes to have its own servers in its
own labs because the funding model works best that way), but the case
study also brought up New York City Mayor Michael Bloomberg’s 10-
year-plan for New York City on reducing carbon emissions by 30 percent
based on 2007 levels. The University has committed to that 30 percent
reduction, even in the face of greatly increased growth in high perform-
ance computing (HPC) requirements fueled by the worldwide research
community.
The people at Pearson Education and IBM Press who worked with me
on this project deserve a special thank-you for helping complete this
project in a relatively short time. The Senior Acquisitions Editor was
Katherine Bull (a fellow Notre Dame graduate), and the Development
Editor was Kevin Ferguson. Kevin has a significant background in green
technology that proved to be a great help. Cindy Teeters was a great help
with the paperwork related to the book contract. On the IBM Press side,
