Power consumption projection
First Claim
1. A method for projecting power consumption, comprising:
- identifying a set of devices of an infrastructure whose power consumption is to be projected;
determining a maximum power consumption of the set of devices;
determining a power adjustment factor for the set of devices, the power adjustment factor representing an upper limit and a lower limit of the maximum power consumption typically consumed by devices similar to the set of devices; and
adjusting the maximum power consumption of the set of devices by the power adjustment factor to derive a projected power consumption for the set of devices;
wherein the power adjustment factor dynamically changes in response to updates in historical power consumption information associated with the devices similar to the set of devices.

Abstract
The present invention provides a way to more effectively estimate energy usage by devices such as servers, including traditional mainframes as well as other enterprise systems. One core idea surrounds the fact that when detailed power consumption information is unavailable for a specific configuration, power consumption is computed/projected/estimated by de-rating the maximum power rating by a power adjustment factor that would more closely project the true power consumption. Under this approach, the power consumption is then provided as a range specifying probable expected lower and upper limits for a given device. This range is more meaningful for planning and decision-making and shows the client a more likely best and worst case energy consumption scenario for their specific device(s), and hence is helpful for planning or server comparison decisions. Cooling, energy costs, energy efficiency, and energy expanded per MIPS are also projected and given as a range instead of a single number. This gives the IT decision maker more accurate information upon which to base IT decision-making.
