Patent ID: 8145927

Claim:
An operation management method in an information processing system having a plurality of information processing devices and cooling equipment and deciding workload allocation to the information processing devices with an operation management device previously storing specification information of each information processing device, the method comprising: obtaining at least one device-specific coefficient of performance (COP) relating to each information processing device, based on heat generated from the information processing devices and electric power of the cooling equipment for exchange of the heat; obtaining index values indicating performances of each information processing device per unit power consumption relating to total power consumption of each information processing device at previously specified resource utilization ratio for each information processing device, respectively, and power consumption of the cooling equipment for cooling heat to be generated from each information processing device corresponding to the power consumption of each information processing device, based on the specification information of each information processing device and the at least one device-specific COP relating to each information processing device; deciding workload allocation by allocating workloads based on the index values; when the index values are obtained, power consumption of each information processing device at the previously specified resource utilization ratio is obtained based on the specification information of each information processing device, power consumption of the cooling equipment for cooling heat to be generated from each information processing device corresponding to power consumption of each information processing device is obtained based on the at least one device-specific COP relating to each information processing device, and index values indicating performances of each information processing device per unit power consumption relating to total power consumption of the power consumption of each information processing device and the power consumption of the cooling equipment are obtained.
