The use of Power Usage Effectiveness (PUE) as a marker for data centre efficiency is to be welcomed but is not without its flaws, those involved in server room monitoring might agree.
Writing for Earth and Industry, Eric Woods, an analyst at Pike Research, noted that improving the efficiency of IT equipment without the same efforts for the cooling and power infrastructure will cause a PUE rating to increase.
"As in many areas of energy efficiency, making the true energy cost of any operation visible and assignable is a key step to improving the way we use resources," he wrote.
"What this means for data centre management is that we will need to become more savvy about the work being done in the data centre and its relationship to energy costs."
One solution to the problem of reducing energy usage is to switch off the servers that are unproductive.
Mr Woods referenced research from the Green Grid suggesting that around 15 per cent of servers in a data centre draw power but do not run any useful application or service.
Turning off the comatose servers could see an improvement in a centre's PUE rating.
