From Greg Linden comes a link and a reference to a very interesting book by two Google engineers: The Datacenter as a Computer: An Introduction to the Design of Warehouse-Scale Machines (PDF, 2.8Mb) by Luiz André Barroso and Urs Hölzle. This is a fascinating introduction to data center design, with useful discussions of architecture, how to do cooling and reduce power use (it turns out, for instance, that getting computers that use power proportionally to their level of use is extremely important).
I suspect that even highly experienced data center designers will find something useful here. The book is written for someone with some degree of technical expertise, but you do not need a deep background in computer science to find much here that is interesting and useful.
One of my recurring ideas (and I am by no means alone in thinking this) is that the Norwegian west coast, with its cool climate, relatively abundant hydroelectric energy and underused industrial infrastructure (we used to have lots of electrochemical and electrometallurgical plants) could be a great place to do most of Europe’s computing. Currently we sell our electric energy to Europe through power lines, which incurs a large energy loss. Moving data centers to Norway and distributing their functionality through fiberoptic cables seems a much more effective way of doing things to me, especially since that region of the country has a reasonable supply both of energy engineers and industrial workers with the skill set and discipline to run that kind of operation.
Now, if I could only find some investors…
