Time-variant use models in constraint-based it resource consolidation

Abstract

A method, system, and computer program product for automated data center platform consolidation. The method commences defining a set of source platforms (e.g., servers, database machines, network infrastructure components, etc.) where the source platforms are associated with time-variant demand models (e.g., computing demand during the working/daytime periods, demand at night, etc.). The demand models can be measured or estimated, and can be in any units of time (e.g., days, hours, etc.). Then a set of target platforms is defined where a member of the set of target platforms has a respective target platform profile comprising an initial time-variant availability model to compare with the time-variant demand models of the source platforms. Time-variant constraints (e.g., not more than 80% utilization during working/daytime periods, etc.) are observed while mapping members of the set of source platforms to the members of the set of target platforms until a consolidation stopping condition is reached.
