Principles and Practices of Enterprise IT Efficiency @microsoft_green #cleantech

Energy efficiency changes in one layer of the IT stack can affect energy efficiency in other layers. For instance, improving the energy efficiency of servers in a data center by 50% can also save energy at the building layer because less energy is required for power distribution and cooling. If you reduce server power consumption and you don’t add new servers to consume the power difference, you could end up actually making the PUE worse because the cooling systems in many data centers are sized to extract a specific range of heat. This might seem like a bad thing, but if you are producing at least the same amount of useful work with less energy, it’s worth the sacrifice. This is one examples where understanding the metrics is crucial in achieving one’s goals.
