Energy meters now running in the Data Centre

Our IP energy meters are up and running in the University data centre, thanks to the efforts of Conrad Bright and Christiaan Brand. We will now watch the results and learn about the DC’s consumption. The one meter measures total supply to the DC, while the other measures output from the UPSs (i.e. power to computing equipment). The meters started logging at around midnight. The night was cool and the servers not that busy, yet it seems that PUE was in the range 2 to 2.2 (roughly). This means that for every watt going to the computers, another is going to the aircons. It will be interesting to see how it changes as the day heats up.

Next steps are to a) provide a dashboard on this blog and b) correlate readings with local weather data.
