Patent ID: 10073801

Abstract:
A computer achieves an increase in throughput by controlling a connection state between each port of an I/O controller and an I/O switch, thereby improving throughput imbalance between the ports of the I/O controller. The computer is provided with: an I/O switch; an I/O device connected to the I/O switch; a management controller; and an I/O controller including a plurality of ports. The management controller detects a connection state with the I/O switch, and acquires the number of virtual switches associated with the detected connection state with the I/O switch by referring to configuration management information for managing the connection state with the I/O switch in association with the number of the virtual switches. The management controller sets the acquired number of the virtual switches for each I/O switch that is connected. Each port of the I/O controller connects with the I/O device via the virtual switches that are set.
