1. A computer server comprising: a plurality of parts of a hardware resource, the parts including an input/output unit and being installed in a single cabinet together, each of the parts being assigned to one of a plurality of partitions; a switching hub including a plurality of ports, the ports being able to be connected to the input/output unit; and a management device to manage the computer server, wherein the management device comprises: a component information acquisition unit that is configured to obtain hardware component information indicating a relation between each of the parts of the hardware resource and each of the partitions, to determine an input/output unit assigned to each partition by using the obtained hardware component information, to generate a setting screen for setting an operation condition of only a port of the switching hub physically connected to the determined input/output unit, to display the generated setting screen, and to obtain an operation condition to be set to each port inputted through the generated setting screen; and a setting unit configured to set the obtained operation condition to the switching hub, wherein: the obtained hardware component information contains assignment information indicating assignment of an interface unit that provides, for each port, an interface with the switching hub in the computer server; the device further comprises a setting information acquisition unit configured to obtain setting information about each port of the switching hub, by correlating the setting information to the partition which uses the port; the setting unit performs the setting of the port, by using both the assignment information of the interface unit and the obtained setting information; the device further comprises a component modification information acquisition unit configured to obtain modification information of components of each partition; when the component modification information acquisition unit obtains the modification information, the setting unit takes over the setting of the port made by using the setting information, and modifies the setting of the port made by using the obtained hardware component information, according to the modification information; the component information acquisition unit generates, as the setting information, a setting screen for setting the operation condition, and displays the generated setting screen; and the setting unit sets operation conditions inputted through the generated setting screen to the switching hub.
