Power usage effectiveness (PUE) has become a commonly used metric for data centre managers to monitor energy efficiency, but when quoted in isolation it can often portray a misleading picture of a data centre’s overall energy usage.
Enlogic is now calling for companies to stop using PUE alone but in combination with more modern solutions, like intelligent PDUs, and performance related metrics to accurately measure energy consumption and enable real energy consumption savings initiatives.
‘Achieving success in a competitive market place is about finding efficiencies and optimising operational costs,’ said Mike Jansma, cofounder and chief marketing officer of Enlogic. ‘For years data centre managers have been convinced that PUE is the magical metric that will give them this competitive edge – but it’s not.
‘The potential energy and financial savings that data centres could achieve are entirely overlooked when PUE is used as a single efficiency metric. The most energy efficient data centres are actually reducing overall energy consumption and costs by looking holistically at PUE in conjunction with IT performance per watt type metrics.’
