Also the industry is working very hard to promote and improve energy efficiency. There are two relavent industry agencies: ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) technical committee 9.9 and The Green Grid. T.C 9.9 has published several books: Best Practices for Datacom Facility Energy Efficiency, High Density Data Centers – Case Studies and Best Practices, Liquid Cooling Guidelines for Datacom Equipment Centers which can be purchased at the ASHRAE.com bookstore. They are also hosting 5 free workshops in NY, http://www.ashrae.org/pressroom/detail/16615. The Green Grid’s website is thegreengrid.org.

1) While industry is using some sub-optimum AC/DC power supplies, the limit of power supplies efficiency may not be at 75% that you referenced.

“Power-converter efficiencies are in the upper nineties and quickly approaching the magic 100% barrier.” (Hearst Electronic Products Monday June 30th 2008, LOU PECHI Power-One, Camarillo, CA

2) A more easily achievable goal would be to increase the server use from “6%”. Virtualization is available for most server platforms and increase the usage factor significantly. This approach to reducing the heat load in a data center is true heat savings (Planning figures are about 10 to 1, that is one virtualized server can handle 10 current servers load).

3) New technology hard drives, i.e. solid state drives (SSD), decrease the heat load in a data center by reducing the power needed to turn drives. While still fairly expensive compared to conventional drives, SSDs can quickly pay for themselves by reduced power and heat. If I remember correctly they require about 10% of a conventional HD.

We are currently undertaking a air-side economizer project for our data center. You can read more about it here: http://redrocksdatacenter.com/green and we’ve started a blog to cover the construction: http://ae.redrocksdatacenter.com

In addition, we’ll begin construction on a new building next year that will be 100% DC. We sit on over 85 acres and are planning on putting up > 30Kw of solar arrays. These are fun projects and hopefully other data center owners will take notice.
