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:
- Lower power processors *
- High-efficiency power supplies **
- Power management features
- Blade servers
- Server virtualization
- 415V AC power distribution
- Cooling Best Practices
- Variable Capacity Cooling and Variable Speed Drives.
- Supplemental Cooling
- 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.
