The federal Environmental Protection Agency recently found that a data center’s uptime has no statistically significant effect on its energy efficiency. But does the claim hold water?
At first blush, it would seem that uptime would hurt data center efficiency. Typically the more uptime a facility has, the more redundancy it has to build in to account for equipment failure. But that apparently is not as large a factor as other design elements.
“Tier level was not a huge predictor of energy performance,” said Alexandra Sullivan, an engineer in the EPA’s Energy
