DIGITAL EDGE
A useful demonstration of its effectiveness can be found by examining the Manila facility , NARRA1 , which achieved a PUE of 1.15 at 75 % load during phase on commissioning , surpassing an already-ambitious design PUE of 1.193 .
This compares to a global PUE average of 1.55 .
“ You can see we ’ re reducing our PUE by 0.4 in comparison to the average site , which is huge ,” adds Park . “ We believe this makes NARRA1 one of the most energy-efficient data centres in the Philippines .”
Taking a holistic approach Power usage effectiveness is , of course , a standard metric for measuring power consumption in data centres , pitting the energy used by computing equipment against the energy delivered .
While using PUE is a popular and easily-applied method for calculating energy efficiency , it has its limitations in that it doesn ’ t necessarily take into account all internal and external factors .
Despite Digital Edge ’ s impressive PUE performance across its various sites , Park contends that operators should be looking beyond PUE and taking a more holistic approach .
“ To achieve true sustainability , we need to look beyond the data centre ,” he says . “ What I mean is we must look from start to end – the power plan all the way to the servers . It can ’ t just be the data centre piece , but the whole thing .”
A number of other factors must also come into the equation , including the sourcing of renewable energy .
