Optimize Server Utilization for Energy Efficiency
Energy Proportionality of Servers
Servers are most efficient at high utilization rates:
Energy Proportionality of Servers and Dynamic Range
Overall Energy Reduction Potentials
Comparison between change in IT utilization and change in PUE
Intel Gold 6230 Xeon processor (The Green Grid database):
- 40% utilization: 286 watts (W)
- 20% utilization: 267 W
- β Reduction: 45%

β Better server utilization is often much more important than increasing the PUE.
