Management apparatus, management system, method for controlling management apparatus, and program

A management system configured by comprising:

• one or more expansion apparatuses in which an internal function can be changed;
• one or more virtual machines that use the internal function of the expansion unit;
• and
• a management apparatus connected to the expansion apparatus and the virtual machine;
• wherein the expansion apparatus comprises:
• a function expansion control part including a storage area for storing information for causing the expansion apparatus to operate;
• and
• a function storage part in which a function executed by the expansion apparatus is stored;
• the management apparatus comprises:
• a data holding part that holds a function management table for storing information associating apparatus identification information identifying the expansion apparatus and function identification information for identifying a function that is set in the expansion unit;
• a function management part that specifies an expansion apparatus used by the virtual machine, in response to an instruction to start up the virtual machine, that sets, in the expansion unit, function identification information corresponding to a function satisfying a functional requirement for the virtual machine, that sets the function satisfying the functional requirement as the internal function in the expansion unit, and that stores the function identification information in the function management table;
• and
• a function setting part that determines driver software necessary for the internal function of the expansion apparatus based on the function identification information set in the expansion unit.

A control method for a management apparatus connected to one or more expansion apparatuses in which an internal function can be changed, and one or more virtual machines that use the internal function of the expansion unit, the method comprising:

• storing information associating apparatus identification information identifying the expansion apparatus and function identification information for identifying a function that is set in the expansion unit;
• specifying an expansion apparatus used by the virtual machine, in response to an instruction to start up the virtual machine;
• setting, in the expansion unit, the function identification information, corresponding to a function satisfying a functional requirement of the virtual machine;
• setting a function satisfying the functional requirement as the internal function in the expansion unit;
• storing the function identification information in the function management table;
• and
• determining driver software necessary for the internal function of the expansion apparatus based on the function identification information that has been set in the expansion unit.
