Abstract:
1. A management computer comprising: a processor; a display unit coupled to the processor; and a memory coupled to the processor, wherein, when setting up a plurality of virtual file servers on first and second file server devices respectively, each of the first and second file server devices including a plurality of network interfaces, the processor instructs the first and second file server devices to configure the plurality of virtual file servers respectively by allocating physical resources of the first and second file server devices to each of the plurality of virtual file servers assigned to the first and second file server devices respectively, the physical resources including the plurality of network interfaces, wherein the first and second file server devices are coupled to a storage system including a logical unit shared by the first and second file server devices, the shared logical unit storing configuration information indicating which of the plurality of network interfaces is allocated to which of the plurality of virtual file servers, and service state information including routing information for each of the plurality of virtual file servers on the first and second file server devices to communicate with devices through a network, wherein, when a first virtual file server of the plurality of virtual file servers on the first file server device fails over to a second virtual file server of the plurality of virtual file servers on the second file server device, the second virtual file server reads out the configuration information and the service state information from the shared logical unit, and defines a communication path between one of the plurality of network interfaces of the second file server device allocated to the second virtual file server and the devices by using the read out routing information for the first virtual file server, and wherein the plurality of network interfaces included in each of the first and second file server devices is implemented for the first and second virtual file servers respectively provided in the first and second file server devices.
