Power budget allocation in a cluster infrastructure

摘要

A system and method for allocating power resources among host computers in a cluster uses lower and upper bounds with respect to a power budget to be distributed to each of the hosts. Each host is allocated a portion of the cluster power capacity. Any excess amount of the capacity is then allocated to the hosts based at least partly on the lower bound (reserve capacity) and the upper bound (host power limit) of each of the clients.

1. A method comprising:
receiving a power limit of a cluster, wherein the cluster comprises a plurality of host computing machines; calculating a total power usage of the plurality of host computing machines; determining a spare power capacity based on a power budget of the cluster and the total power usage of the plurality of host computing machines; and allocating a portion of the spare power capacity to at least one of the plurality of host computing machines based at least partly on the spare power capacity.
