Abstract

The present invention provides a METHOD TO CALCULATE AN ENERGY EFFICIENCY RATING for information technology equipment. This method specifically pertains to information technology equipment that doubles its capabilities in a predetermined timeframe according to Moore'"'"'s Law.

This method uses a formula to calculate an energy efficiency rating based on power consumption and transactions per second. It further calculates a normalized rating where the absolute rating is adjusted based on Moore'"'"'s Law prediction of improvements. As a result the method invented is the first and only method to compare information technology from various generations of hardware, processor and component architecture with each other in terms of their energy efficiency.

Claims

1. A method to calculate energy efficiency of information technology equipment

a. The method of claim 1 wherein said method is used to calculate an absolute rating of energy efficiency of information technology equipment.

b. The method of claim 1 wherein said method is used to calculate a normalized rating of energy efficiency of information technology equipment over time.

c. The method of claim 1 wherein said method is used to generated a normalized ratings graph for information technology equipment that shows the expected rating of such equipment over time and in the future.

d. The method of claim 1 wherein said method is used to give purchasing guidance based on said energy efficiency ratings so that equipment purchasing decisions can include performance per energy usage.

e. The method of claim 1 wherein said method is used to provide a common metric and measure and basis for additional comparisons of equipment performance per energy consumed.
