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:
- The removal and shipment of the Lawrencium cluster to San Diego Super Computer Center. The reduced IT load and heat generated by the cluster is causing the room to over cool raising the PUE. We will attempt to save power and raise the room temperature by manually turning off air handlers until the new Synapsense software is operational.
- Progressing work to allow automatic adjustment of air flow. We have installed variable speed fan motors in the air handler units. The air handlers will be connected directly to the room environmental monitoring system, which in turn will automatically adjust air flow depending on IT power consumption and heat load and may allow us to turn off air handlers, which will improve our PUE.
- The new software required for this functionality is due in early October.
