Information apparatus and method of optimizing cooling efficiency of air conditioner

Abstract

An air conditioner that cools inside a room wherein a plurality of server apparatuses is arranged, is driven with high efficiency. An information apparatus is communicatively coupled to a plurality of server apparatuses each capable of implementing a virtual server, stores a relation between a cooling performance and a cooling efficiency of an air conditioner that cools a room wherein the server apparatuses are arranged stores a history of load on each of the server apparatuses, the load being generated by a virtual server implemented in the server apparatus, creates a plurality of virtual server allocation patterns having varying allocations of virtual servers to be implemented by the server apparatuses, simulates, for each of the created allocation patterns, an amount of heat generation of each of the server apparatuses on the basis of the history of load on the server apparatus, seeks a cooling performance required to be offered by the air conditioner on a basis of the simulated amount of heat generation, and identifies the allocation pattern with which the cooling efficiency corresponding to the sought cooling performance is not less than a threshold set in advance.
