THE CHILL OFF

 

Chill Off 2 Results presented, October 14 2010!

The results of the Chill Off 2 were presented at the Silicon Valley Leadership Group Data Center Efficiency Summit hosted by Brocade in San Jose, CA. http://dcee.svlg.org

The presentation was moderated by Jeremy Rodriguez, Co-Chair of the DCP Technology Advisory Board. On the panel were Henry Coles from Lawrence Berkeley National Labs, Mike Ryan from Google (DCP TAB Member) and Dean Nelson from Ebay (DCP Chairman and Founder).

Henry Coles, who defined the metrics and executed the independent testing presented the findings before the panel discussion. See the full report on the LBNL website.  Also, you can view all of the Chill Off 2 product videos on the DCP YouTube channel:

After the CO2 results were presented and the panel discussion concluded, Dean Nelson surprised the audience with a peak into the pre-test of the Chill Off 3. Stay tuned to this page for more details on those pre-test results and the upcoming Chill Off 3 testing in 2011. For more information, email feedback@datacenterpulse.org.

 

What did we accomplish?

  • Expand on 2007-08 Chill Off testing
  • Compare current cooling technology efficiencies with compute loads between 6kW-30kW/per cabinet
  • Compare cooling performance w/ higher air inlet, varying supply water temperatures, & varying/mixed work load
  • Compare vertical vs horizontal compute scaling
  • Compare powering-off vs power-throttling of servers
  • A controlled test environment that will enable equal comparative testing between the different solutions
  • Publish an industry report on the findings
  • Continue to foster the cooperative and innovative work of the SVLG datacenter demonstrative projects
