Power performance is a measurement of data center efficiency. How efficiently does a datacenter use electricity to power its systems, including cooling and backup power. Power consumption is tied closely to the overall physical data center footprint as well as its carbon footprint. Less power, less space, and less carbon equate to lower costs and greater sustainability.

Data center efficiency can be effectively measured by calculating the performance per rack. The performance per rack metric details analysis at the rack level including power consumption, rack density, and the physical data center footprint and combines it with performance metrics/targets. Ultimately, this kind of analysis yields more sustainable data center designs for the modern cloud era.
