Energy-related costs are rising faster than any other expense in the data center, a Gartner report has found. And if IT managers are going to get a handle on energy costs, they need to do more to measure and understand how those watts are being burned.

Gartner says energy-related costs now account for about 12 percent of overall data center expenditures, and despite many innovations in the data center to reduce energy consumption, the picture is likely to get worse.

“With upwards of 5 percent growth for server shipments predicted per year over the next two years, organizations need to forcefully control their energy consumption and costs,” Rakesh Kumar, a research vice president at Gartner, said in releasing the report. “To do this, data center operators need to measure energy-related data across the whole site, including the building, the facility’s components and the IT equipment portfolio.”

To develop a better understanding of energy consumption in the data center, Gartner says continuous power utilization efficiency (PUE) readings will become the norm for most large data centers. By 2015 it expects 80 percent of new large data centers will report continuous readings across the data center.
