Controlling apparatus, and controlling method

摘要

A controlling method realized by a computer connected to a plurality of physical devices in which respective virtual machines (VMs) are operated and a process device which is connected to the plurality of physical devices with a plurality of routes and in which a plurality of duplication process VMs for executing a duplication process of duplicating data used by the plurality of VMs to a memory device, the method includes: acquiring loads of the plurality of routes and percentages of completion of the duplication process executed by the plurality of duplication process VMs; and, when incompletion of the duplication process using the selected route within a regulated time is detected, moving any of the duplication process VMs using the selected route to any of the plurality of physical devices from the process device.
