Data center power consumption has become a major concern in recent years, as utilities struggle to keep up with growing demand and operators are forced to seek alternative ways to keep the lights on.
How Anyone Can Dominate DCS (You're Wasting Time Not Doing This)
According to the Uptime Institute, reducing energy consumption—and ultimately lowering operating costs—can be as simple as flipping a switch on one of the performance and energy management mechanisms built into modern systems.
We're not talking about a trivial amount of power either. In a blog post this week, Uptime analyst Daniel Bizo wrote that simply enabling OS-level controls and power profiles can result in a 25 to 50 percent reduction in power consumption. Scaled across an entire data center, these savings add up quite quickly.
In addition, enabling the processor's C-state can lead to an almost 20 percent reduction in idle power consumption. In a nutshell, C-states dictate which aspects of the chip can be turned off during sleep periods.
