US Patent 10528115 Obtaining smoother power profile and improved peak-time throughput in datacenters

Disclosed embodiments include a method performed by a computing device of a computer system having a hierarchical arrangement of power nodes including servers. The method includes determining power utilization patterns of the servers, calculating asynchrony scores for the servers based on the power utilization patterns, and clustering the servers into clusters based on the asynchrony scores, where each cluster has servers that have synchronous utilization patterns. The method also includes allocating the servers to the hierarchical arrangement of power nodes by selecting servers from the clusters to reduce synchronous power utilization patterns by the hierarchical arrangement of power nodes.
