Metrics developed by The Green Grid for data centre efficiency.
Metrics are used in order for data centres to measure IT performance and improve on problem areas. The metrics range from granular technical information, which is used by data centre staff, to key performance efficiency indicators that inform the business groups relying on the data centre.
The importance of data centre metrics has risen to extreme importance over the past years, which has led to the emergence of different types of metrics.
The Green Grid, however, recently released a warning as IT leaders with data centre responsibilities are using a range of metrics which are too narrow or have not deployed the necessary tools to get the required detail of measurement in order to drive efficiency.
Based on this, CBR put together a list of the top five metrics, developed by The Green Grid, which support data centre efficiency.
Power Usage Effectiveness (PUE)
Created by The Green Grid, PUE is considered as the ratio of total facilities energy to IT equipment energy. It has also been identified as one of the best metrics available to determine a data centre’s energy efficiency.
PUE is able to determine opportunities to improve a data centre’s operational efficiency, how a data centre compares with its competitors, if the data centre operators are improving the designs and processes over time and also reveals opportunities to repurpose energy for additional IT equipment.
This metric makes clear focus of the total facility power and IT equipment power, with cooling being one of its major players in PUE measurement.
