POINT-IN-TIME BASED ENERGY SAVING RECOMMENDATIONS
First Claim
Patent Images
1. A computer implemented method comprising:
- retrieving historical usage data in response to a request to generate energy saving recommendations for a data center, wherein the historical usage data represents energy usage of the data center;
determining usage patterns in the historical usage data based on statistical analysis;
determining repetitions of the usage patterns;
generating energy saving recommendations that indicate energy saving actions to initiate at particular times based on the usage patterns and the repetitions;
determining a business constraint of the data center; and
refining the energy saving recommendations based on the business constraint.

Abstract
Energy saving efforts should not compromise data center performance. An energy management application can determine usage patterns in historical energy usage data based on statistical analysis and energy models. Energy savings recommendations can be generated for future points-in-time based on the usage patterns. Business constraints can be applied to the energy savings recommendations to ensure that the energy savings recommendations meet performance requirements.
