<p>Power saving of a data center is realized by learning a correlation between a state of cooling efficiency of the entire IT equipment units (101a - 103b) and a workload of each IT equipment unit (101a - 103b) from an operation history (10) and placing a workload on an IT equipment unit (101a - 103b) by using the correlation. An IT workload placement optimization function (20) samples data from an operation history (10) of various IT equipment units (101a - 103b) in a server room (100) by using three criteria of temperature, workload, and time, classifies the data into cooling efficiency conditions of the entire IT equipment units (101a-103b), and outputs a workload placement directive for determining placement of workload on each IT equipment unit (101a - 103b) from the correlation between the cooling efficiency condition and the workload to a workload management server (160), so that the workload management server (160) can effectively extract influence on the cooling efficiency from the operation history (10) and use the influence to place the workload.</p> |
