The Efficiency Opportunity Roadmap

The Efficiency Opportunity Roadmap

(CPU/RAM/disk/network) can be configured, based on examination of an application’s performance characteristics, to ensure that they are neither “starved” due to bottlenecks in other systems nor overbuilt and mostly idle. This balancing activity can significantly reduce the system’s overall power draw and reduce costs while potentially improving performance. For systems such as servers that are on nearly 24/7, an efficient power supply can significantly reduce the amount of energy consumed and more than pay for itself in energy savings. For instance, a server that requires a near-constant 500 watts of DC power will consume about 1100 fewer kWh per year using an 85% efficient power supply than one that is 70% efficient ($110/year savings at 10 cents per kWh). Most computer hardware components draw power whether they are used or not. Configuring hardware to contain only compo...
