Alger addresses the problem of an ever increasing cost of running a data center. Unappreciated by most users of the Internet, this increase is a direct result of its popularity. The key concept of the book is to have several data center efficiency metrics. The most important is, of course, power consumption. This should [must] be minimised. Power turns out to be the main cost of most centers. Another factor to minimise is the amount of carbon dioxide that is produced. However the latter is hard to measure directly, whereas the power bill is explicit each month. While laudable it is to look at carbon dioxide, in practical terms, the reader should perhaps focus on power consumption. The text also has a nice summary of different national green certifications. Several countries have put serious effort into these, and the location of your data center should direct you first to its national certification as something to adhere to. Given that power should be minimised, how? Many tips are furnished. The simplest perhaps is to have a 'cool roof'. One that is highly reflective. In hot weather, this reduces directly the amount of solar heat absorbed by the center. Another good idea is to look at landscaping. If possible, try to have trees that shade buildings and parking lots. Inside the center, attention should be paid to improved internal cooling designs. Also, try using fibre instead of copper to transmit signals between the computers. Fibre has much greater bandwidth than copper, and these days it is often cheaper to produce. Another saving with fibre is that a fibre bundle is thinner than a copper cable bundle that would carry the same amount of traffic. So there is less airflow obstruction. However, the biggest power saving could be to move to virtualisation. It can greatly improve the usage of your existing machines, and so reduce the need to keep buying more computers.
