System, control method of system, and storage medium

A system comprising:

• a plurality of computers each of which provides a first cooling apparatus;
• a second cooling apparatus configured to cool the plurality of computers by supplying air thereto;
• and
• a computer coupled to the second cooling apparatus, wherein
• the computer includes:
• a memory;
• and
• a processor coupled to the memory and configured to:
• cause the second cooling apparatus to supply air at a first airflow rate to the plurality of computers;
• acquire first information on power consumption of the plurality of first cooling apparatuses in the plurality of computers and power consumption of the second cooling apparatus, when the second cooling apparatus supplies the air at the first airflow rate;
• cause the second cooling apparatus to supply air at a second airflow rate to the plurality of computers after the first information is acquired, the second airflow rate being a value obtained by changing the first airflow rate by a predetermined amount;
• acquire second information on power consumption of the plurality of first cooling apparatuses in the plurality of computers and power consumption of the second cooling apparatus, when the second cooling apparatus supplies the air at the second airflow rate;
• and
• change the airflow rate of the second cooling apparatus by the predetermined amount, based on a comparison result between changed amount of the power consumption of the plurality of first cooling apparatuses in the plurality of computers and a changed amount of the power consumption in the second cooling apparatus caused due to the change of the airflow rate from the first airflow rate to the second airflow rate.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process comprising:

• acquiring first information on power consumption of a plurality of first cooling apparatuses in a plurality of computers and power consumption of a second cooling apparatus under a condition that the second cooling apparatus supplies air at a first airflow rate to the plurality of computers;
• causing the second cooling apparatus to supply air at a second airflow rate to the plurality of computers after the first information is acquired, the second airflow rate being a value obtained by changing the first airflow rate by a predetermined amount;
• acquiring second information on power consumption of the plurality of first cooling apparatuses in the plurality of computers and power consumption of the second cooling apparatus under a condition that the second cooling apparatus supplies the air at the second airflow rate;
• and
• changing the airflow rate of the second cooling apparatus by the predetermined amount, based on a comparison result between a changed amount of the power consumption of the plurality of first cooling apparatuses in the plurality of computers and a changed amount of the power consumption in the second cooling apparatus caused due to the change of the airflow rate from the first airflow rate to the second airflow rate.
