A storage system includes a first control apparatus; at least one second control apparatus managed by the first control apparatus; and a storage unit accessed by the second control apparatus. The second control apparatus determines based on detection of an error of an input/output process for storage in the storage unit whether the storage is in a blocking state, executes a resumption process of the input/output process when the storage is in the blocking state, judges whether an error occurrence frequency of the input/output process is at least a predetermined value, when the storage is not in the blocking state, and transmits to the first control apparatus, a blocking process request for the storage, when the error occurrence frequency is at least the predetermined value. The first control apparatus executes a blocking process and an error process of the storage, based on reception of the blocking process request.

A virtual machine management device includes an acquiring unit, a specifying unit, and a move processing unit. The acquiring unit acquires an amount of communication data that is exchanged between multiple virtual machines running in multiple server devices and that is used for communication with each other. The specifying unit specifies, on the basis of the communication distance between each of the server devices, a server device that has a shorter communication distance from a server device, which executes one of a pair of the virtual machines whose amount of the communication data is equal to or greater than a predetermined amount, than a communication distance between the server devices in which the pair of the virtual machines are running. The move processing unit moves the other one of the pair of the virtual machines to the specified server device.
