SYSTEM AND METHOD FOR CONTROLLING VIRTUAL-MACHINE MIGRATIONS BASED ON PROCESSOR USAGE RATES AND TRAFFIC AMOUNTS

摘要

Plural virtual machines are executed by plural information processing devices coupled to each other via a network and connected to plural storage devices, where each information processing device executes one or more virtual machines by using a processor thereof. When first virtual machines used for distributed processing are created, a management device monitors a utilization ratio of the processor used for each of the first virtual machines, a first communication volume used for an access of each of the first virtual machines to one of the plural storage devices, and a second communication volume used for arithmetic processing of each of the first virtual machines performed on data stored in the plural storage devices. The management device controls a migration of each of the first virtual machines between the plural information processing devices, based on the utilization ratio of the processor, the first communication volume, and the second communication volume.
