We have never worked on a Data Center project but the topic interests me. I love computers, the Internet and Energy Savings. A Data Center is at the center of all three. [Note this entry has been update a couple times, see ‘Additional Resources’ for more information.]

Although we haven’t work on Data Centers our partner Xcel Energy has. As a utility they have many resources available including a Data Center Efficiency program. Follow the link or call 1-800-481-4700 for more information. Note: be sure to select a state or else the link won’t work properly- I know Minnesota works.

There is a very good overview of the topic in the November 2008 Issue of ASHRAE Journal.  The authors look at the entire system and identify ten energy saving strategies:

  1. Lower power processors *
  2. High-efficiency power supplies **
  3. Power management features
  4. Blade servers
  5. Server virtualization
  6. 415V AC power distribution
  7. Cooling Best Practices
  8. Variable Capacity Cooling and Variable Speed Drives.
  9. Supplemental Cooling
  10. Monitoring and optimization: Cooling units work as a team

*AnandTech Low Power CPU Shootout.

** I’ve often wondered if there would be some savings bringing in 12 VDC and 5VDC power to the servers and putting all the power supplies a  separate area.
