The management computer has a memory which stores management information and management programs, and a CPU which refers to the management information and executes the management programs; the management information includes storage management information for allowing determination as to whether the plurality of storage resources can be paired in a redundant configuration, and couplable configuration management information for determining whether the plurality of storage resources and the plurality of server resources can be connected to each other; and when the CPU deploys a virtual machine, the CPU first determines, by reference to the storage management information, storage resources to be paired in a redundant configuration, then selects, by reference to the couplable configuration management information, server resources each of which can be connected to a respective one of the storage resources that are to be paired in a redundant configuration, and pairs the selected server resources in the redundant configuration.
