October average Power Usage Effectiveness (PUE): 1.55

  • Average Power Consumption: 
    • 350kW IT – 64.2%
    • 1kw Lighting – .2%
    • 24.1kw Building and IT Losses – 4.5%
    • 170 Cooling Power – 31.1%
  • Average Cooling Load: 99 tons
  • Available Rack Space: 71

Data Center Efficiency Progress:

The DOE national average PUE for data centers is 1.75. 50B-1275 data center has evolved from an average PUE of 1.65 (calculated in 2009) to today’s 1.47. Getting there, staying there, and further improving the PUE is an ongoing effort.

Key highlights for this month include:

  • CPU energy use has continued to decrease during the month due to drop in CPU utilization, dropping the total IT energy use to about 2007 levels.
  • The new VFD software to automatically control the Air Handler air flow was installed mid month.  To enable testing we turned on all the air handlers.   For these reasons the PUE has gone up considerably, which is expected during testing.  By month end we were seeing large swings in CRAC energy use, indicating a possible problem with the software.
