Abstract
A live migration process between different locations is realized without migrating data stored in a storage area to another location. A network device, which is included in each of locations, for coupling to another one of the locations, the network device stores a program for realizing an access processing module for managing accesses, and coupling management information for managing a coupling relationship between the plurality of virtual machines and the plurality of storage areas, and wherein the access processing module is configured to: receive a notification to start a live migration process, refer to the coupling management information to identify a port for accessing a storage area allocated to a virtual machine; acquire an address of a transfer destination device to which an access request is transferred; generate conversion information; and control the access request based on the conversion information.
