What good is great power use effectiveness if your DC is packed with inefficient kit?
Power use effectiveness – PUE for short – has long been the spec by which datacenter efficiency has been measured. But after nearly two decades Nvidia believes it's time for a new metric.
But while Nvidia acknowledges that PUE has helped to drive improvements in computing infrastructure and reduce power lost to cooling, it's far from perfect. Nvidia isn't alone in this line of thinking either. The brainchild behind the metric believes PUE has run its course."It improved datacenter efficiency when things were bad.
"The holy grail is a performance metric. You can't compare different workloads directly, but if you segment by workloads, I think there is a better likelihood for success," Belady argued in the post.
