A load distribution system includes a plurality of storage devices which accept an input processing request or an output processing request and return a processing result, a plurality of I/O processing servers which transmit the input processing request or the output processing request to the one of the plurality of storage devices, receive the processing result, and, when a response time from the transmission of the input processing request or the output processing request to completion of the processing exceeds a threshold, send out an overload response indicating that processing to the input processing request or the output processing request is in an overloaded state, and a plurality of access servers which transmit an input processing request or an output processing request from a user to an I/O processing server which is not in an overloaded state on the basis of the overload response from the I/O processing server. |
