Data Center Efficiency – It's in the Design

Most companies undergoing data center projects have the mindset of cutting costs rather than helping the environment, however, they may want to adjust their focus. With data center greenhouse emissions set to overtake the airline industry in the next five to ten years, quadrupling by 2020, it has never been more critical for organizations to optimize their data center. If the cost savings are half as great for data centers as they have been for the airline industry, we will need to fasten our seatbelts.

Data centers have always been power hogs, but the problem has accelerated in recent years. Ultimately, it boils down to design, equipment selection and operation of which measurement is an important part. The first step on an existing Datacenter to achieve high(er) efficiencies is through the improvement of a data center’s Power Usage Effectiveness (PUEenergy)† ratio PUEenergy ratios can be used as a guide to define a data center’s efficiency or ‘green’ credentials and have become the de facto metric in the past year.

A data center with a low PUEenergy of 1.5, implements lean design and has established measurement data with demonstrable year-on-year improvements can be classified as green or energy efficient. The dream green data center would have a PUEenergy of one, which means that every watt of power in the transformer is delivered directly to the IT equipment without any losses in the site infrastructure. Unfortunately, this is not physically possible as some infrastructure services, such as cooling, always have energy losses (for time being).
