Abstract: A non-transitory computer-readable storage medium that stores a live migration program that causes a computer to execute a process, the process including starting live migration of a virtual machine to another computer in response to reception of an instruction of the live migration of the virtual machine, an emulator which becomes a substitute for hardware capable of dynamically defining a function is implemented in the virtual machine, causing the emulator to execute a requested process requested from the virtual machine to the hardware when a degree of progress taken to transmit data of the live migration of the virtual machine satisfies a first condition, and switching the computer executing the virtual machine to the other computer when the degree of progress satisfies a second condition to determine whether the computer executing the virtual machine is switched and when the hardware is not executing a process of the virtual machine.

Abstract: A control device controls the switch device and the plurality of processing apparatuses such that, when one of replicated data pieces stored in two or more different storage devices among the plurality of storage devices is lost, the replicated data piece stored in a second storage device other than a first storage device storing lost replicated data piece among the two or more different storage devices is copied through the switch device to reconstruct the lost replicated data piece. Thus, a redundancy of replicated data is restored without affecting a bandwidth of a network.

A management apparatus which included in the system is configured to manage the first and second information processing apparatuses, wherein, when data is to be written, the management apparatus outputs a write request to any of the plurality of first magnetic disk devices and any of the one or more second magnetic disk devices, and when data is to be read, the management apparatus outputs a read request to any of the plurality of first magnetic disk devices.

Abstract: A logical information-processing device is allocated based on a request from a terminal device. In an information-processing device, one of plural storage devices is connected to one of plural processing devices each including a managing unit. First correspondence information stores physical identification information identifying the information-processing device in association with address information of the managing unit. Second correspondence information stores the physical identification information in association with logical identification information identifying the logical information-processing device. A managing device obtains address information of the managing unit of the information-processing device corresponding to the logical information-processing device allocated to the terminal device, by using the physical identification information obtained, based on the logical identification information included in the request, from the second correspondence information.
