Increase the temperature Visual result of experiment carried out in the R&D data centre in IBM Dublin During the experiment the flow rate of chilled water supply was reduced. Caution: transient response times increase!
So what’s the research all about To increase overall temperatures we need to control and manage the inlets To control and manage the inlets we need to know at what temperature they are It can be costly and disruptive to deploy 1000’s of sensors Squish Cold-spots Just-right Hot-spots What if we can use previous knowledge gained from gathering all this data from other data centres to make a prediction on ours without the cost.
Example of data sets Image removed 386496 data points distributed geospatially on 8 layers Image removed 217728 data points distributed geospatially on 8 layers The research is based on access to over 100 data sets like these, available from locations all over the world.
Pulling together knowledge Clusters Hybridof knowledge-based model and simplified physics model, but that’s for another day!
