Looking back at the last 10 years, the data centre industry as a whole has made impressive performance improvements. Our research shows that data centres today are 80% more efficient than those built with technology from 10 years ago, and with a significantly reduced cost/watt. However, if current digital trends progress, society will demand more computing power over the next decade, and data center strategies used in the past will no longer be adequate. Where will the next 80% performance improvement come from? This presentation will discuss how software and other technologies may be the answer.
