Patent ID: 8473108

Claim:
An information apparatus, comprising a network port that communicatively couples to a plurality of server apparatuses each configurable to implement a virtual server, an air conditioner characteristic curve management table that stores a relation between a first cooling performance and a first cooling efficiency of a first air conditioner arranged in a first room, and a relation between a second cooling performance and a second cooling efficiency of a second air conditioner arranged in a second room, wherein the first and second air conditioners cool the first and second rooms wherein the server apparatuses are arranged, a performance management table that stores a history of a first load on a first server generated by a virtual server implemented in each of the first server apparatuses arranged in the first room, and a history of a second load on a second server generated by a virtual server implemented in each of the second server apparatuses arranged in the second room, and a migration plan derivation unit that creates a plurality of virtual server allocation patterns having varying allocations of virtual servers to be implemented by each of the first server apparatuses and the second server apparatuses, simulates, for each of the created allocation patterns, a first amount of heat generation of each of the first server apparatuses on a basis of the history of the first load on the first server apparatus, simulates, for each of the created allocation patterns, a second amount of heat generation of each of the second server apparatuses on the basis of the history of the second load on the second server apparatus, seeks a first cooling performance required to be offered by the first air conditioner on a basis of the simulated first amount of heat generation, and seeks a second cooling performance required to be offered by the second air conditioner on the basis of the simulated second amount of heat generation, and identifies the allocation pattern with which the first cooling efficiency corresponding to the sought first cooling performance is not less than a first threshold set in advance and the second cooling efficiency corresponding to the sought second cooling performance is not less than a second threshold set in advance.
