DCO dashboard Energy efficiency

This question was originally posted on DCIM Support by tlb1661 on 2016-07-27


The simple PUE configuration has a place for sensor measurements for total facility load (Power in) and IT load. How is this accomplished when configuring energy systems within the energy efficiency configuration. In the configuration tips it states "

4.  Switchgear

Only one switchgear should be used in a energy system in Energy Efficiency, even if several switchgears exits in the data center configuration.

Switchgears can only be estimated. It is possible to add a script to a switchgear, but it will not be taken into account in the PUE calculation. "

Thanks

Dear Tony,

Please refer the below post which describes the tips for configuring Energy Efficiency. 

Tips for configuring Energy Efficiency

Total Facility Load = IT Load + sum of losses of all subsystems

-> For a switchgear, PDU, UPS : loss = difference in KW between the input and the output of the subsystem. Subsystem losses are calculated either from real measurement (scripts) or from an estimation from a model of the subsystem (Energy Efficiency properties of the subsystem). Note that a script returns the INPUT value of the subsystem.

-> Cooling units, lighting, ventilation and infiltration are considered as 100% losses.

This means that energy efficiency module does not actually calculate the PUE as a ratio of input power and IT Load.

I hope this helps. 

regards,

Bala
