Management computer and management program

A management computer comprising:

• a memory;
• a network interface coupled to a plurality of physical computers;
• and
• a processor coupled to the memory and the network interface, wherein the memory is configured to:
• store association information indicating an association among a first physical computer that is in the plurality of physical computers,
• a virtual computer that is implemented by the first physical computer,
• a first physical resource that is in the first physical computer and allocated to the virtual computer, and a user who uses the virtual computer,
• store failure information indicating a failed physical resource, and store an upper limit value for a destruction amount being an amount of a physical resource that is of the same type as the first physical resource and that has failed by being used by the user, and
• the processor is configured to:
• calculate the destruction amount based on the association information and the failure information,
• determine whether or not the destruction amount is equal to or less than the upper limit value,
• determine based on the failure information whether or not the first physical resource fails,
• determine, upon determining that the first physical resource fails and that the destruction amount is equal to or less than the upper limit value, based on the association information whether or not any of the plurality of physical computers includes a second physical resource that is usable as a replacement for the first physical resource, and
• transmit, upon determining that any of the plurality of physical computers includes the second physical resource, to the first physical computer an instruction to allocate the second physical resource to the virtual computer as a replacement for the first physical resource.
