Apparatus for migrating virtual machines to another physical server, and method thereof

摘要

An apparatus obtains response information including a result of processing executed by a virtual machine operates on the first device, calculates the first value that is used to evaluate a response time from transmission of the request information to reception of the response information, calculates a ratio of processing capability of the first device to processing capability of the second device, calculates, based on the first value and the ratio, a second value that is used to evaluate a processing time until a response for a request is received when the virtual machine operates on the second device, determines the second device to be a migration destination candidate of the virtual machine when the second value is smaller than a threshold value, migrates the virtual machine that operates on the first device to the migration destination candidate to turn off the power of the first device.

主权项

1. An apparatus for controlling an information processing system, the apparatus comprising:
a memory; and a control unit configured to perform a process including: obtaining response information that includes a result of processing executed by a plurality of virtual machines that operates on a first information processing device, in response to request information that is transmitted to the information processing system that includes a plurality of information processing devices, the first information processing device being included in the plurality of information processing devices; calculating a first evaluation value that is used to evaluate a response time from transmission of the request information to reception of the response information; calculating a value that depends on a ratio of a processing capability of the first information processing device to a processing capability of a second information processing device, the second information processing device being included in the plurality of information processing devices and reserving capacity for executing the processing; calculating an occupation proportion of a processing time of each of the plurality of virtual machines in the response time, the processing time being a time taken by each of the plurality of virtual machines to execute the processing; calculating, based on the first evaluation value, the value that depends on the ratio and the occupation proportion, a second evaluation value that is used to evaluate a processing time that occurs when the virtual machines operates on the second information processing device, the processing time being a period of time extending from transmission of the request information to reception of the response information; determining the second information processing device to be a migration destination candidate of the virtual machines when the calculated second evaluation value is smaller than a first threshold value; and migrating the virtual machines that operates on the first information processing device to the migration destination candidate to turn off power of the first information processing device.
