Quick take

  • Understanding the differences between annualized PUE and peak PUE is the first step to accurately comparing energy efficiency between colocation data centers.
  • Differences in energy efficiency from one data center to another will significantly impact your costs and scalability.
  • Learn more about PUE and keeping your costs in check in our new white paper.

By now you’ve probably fielded a question – from your Board, investors, even customers – about the energy consumption of your data centers. You might have sustainability initiatives inside and outside of the data center. But if you’re like most CEOs and CFOs, you might not have even heard of PUE. Yet it’s the metric that more than any other shows how energy efficient a data center is. And it matters well beyond sustainability – it’s a significant driver of cost in the data center.

Power Usage Effectiveness (PUE) is the ratio of all energy consumed by the data center to the energy actually consumed by the IT equipment. It tells you how much energy your IT is using and how much goes to data center overhead.

Differences in energy efficiency from one data center to another will significantly impact your costs and scalability. Making a true comparison between data centers can be difficult, with a lack of transparency around what metrics providers use and how they’re calculated. Understanding the differences between annualized PUE and peak PUE is the first step to accurately comparing energy efficiency between colocation data centers – and keeping your costs in check.

Gain that understanding in the white paper Comparing PUE Between Colocation Data Centers – And Why It Matters.

In the white paper, you’ll learn:

  • The difference between annualized PUE and peak PUE, and why it matters. (Annualized PUE impacts operational costs; peak PUE affects capital costs and your ability to scale up IT load within a data center.)
  • The technology behind our industry-leading 1.15 annualized PUE, which yields a 32% savings over a high-end data center.
  • 8 PUE questions to ask when comparing colocation providers.
