软件质量是被大多数程序员挂在嘴上而不是放在心上的东西！ 除了完全外行和真正的编程高手外，初读本书，你最先的感受将是惊慌：“哇！我以前捏造的C++/C程序怎么会有那么多的毛病？” 别难过，作者只不过比你早几年、多几次惊慌而已。 请花一两个小时认真阅读这本百页经书，你将会获益匪浅，这是前面N-1个读者的建议。

ABSTRACT<br>Over the past few years, the authors benchmarked 22 data center buildings. From this<br>effort, we have determined that data centers can be over 40 times as energy intensive as<br>conventional office buildings. Studying the more efficient of these facilities enabled us to<br>compile a set of “best-practice” technologies for energy efficiency. These best practices include:<br>improved air management, emphasizing control and isolation of hot and cold air streams; rightsizing<br>central plants and ventilation systems to operate efficiently both at inception and as the<br>data center load increases over time; optimized central chiller plants, designed and controlled to<br>maximize overall cooling plant efficiency, central air-handling units, in lieu of distributed units;<br>“free cooling” from either air-side or water-side economizers; alternative humidity control,<br>including elimination of control conflicts and the use of direct evaporative cooling; improved<br>uninterruptible power supplies; high-efficiency computer power supplies; on-site generation<br>combined with special chillers for cooling using the waste heat; direct liquid cooling of racks or<br>computers; and lowering the standby losses of standby generation systems.<br>Other benchmarking findings include power densities from 5 to nearly 100 Watts per<br>square foot; though lower than originally predicted, these densities are growing. A 5:1 variation<br>in cooling effectiveness index (ratio of cooling power to computer power) was found, as well as<br>large variations in power distribution efficiency and overall center performance (ratio of<br>computer power to total building power). These observed variations indicate the potential of<br>energy savings achievable through the implementation of best practices in the design and<br>operation of data centers.

This book assumes that you have some programming familiarity: you<br>understand that a program is a collection of statements, the idea of a<br>subroutine/function/macro, control statements such as “if” and looping<br>constructs such as “while,” etc. However, you might have learned this in<br>many places, such as programming with a macro language or working<br>with a tool like Perl. As long as you’ve programmed to the point where you<br>feel comfortable with the basic ideas of programming, you’ll be able to<br>work through this book. Of course, the book will be easier for the C<br>programmers and more so for the C++ programmers, but don’t count<br>yourself out if you’re not experienced with those languages (but come<br>willing to work hard; also, the multimedia CD that accompanies this book<br>will bring you up to speed on the basic C syntax necessary to learn C#). I’ll<br>be introducing the concepts of object-oriented programming (OOP) and<br>C#’sbasic control mechanisms, so you’ll be exposed to those, and the first<br>exercises will involve the basic control-flow statements.<br>Although references will often be made to C and C++ language features,<br>these are not intended to be insider comments, but instead to help all<br>programmers put C# in perspective with those languages, from which,<br>after all, C# is descended. I will attempt to make these references simple<br>and to explain anything that I think a non- C/C++ programmer would not<br>be familiar with.
