System for and method of managing resource operations

A method of managing real resource operations in a storage system including an information processing apparatus and a storage apparatus communicably connected to the information processing apparatus via a communication network, the storage apparatus writing or reading data to or from a storage device in response to a data write/read request transmitted from the information processing apparatus, the method comprising the steps of:

• setting virtual resources by assigning the real resources;
• managing the overperformance status of the real resources;
• and
• changing the settings in conformity with the overperformance status of the real resources and reduces the real resources assigned to the virtual resources.

A resource operations management system for managing operations of real resources in a storage system including an information processing apparatus and a storage apparatus communicably connected to the information processing apparatus via a communication network, the real resources including a CPU and a memory, the storage apparatus writing or reading data to or from a storage device in response to a data write/read request transmitted from the information processing apparatus, the resource operations management system comprising:

• a virtual resource management unit for setting virtual resources by assigning the real resources;
• and
• a real resource management unit for managing the operating status of the real resources,
• a policy management unit for managing policy data that is data for specifying an execution environment of software;
• and
• a software management unit for accepting entry of programs and data making up the software,
• wherein when the virtual resource management unit changes the setting by assigning the single real resource to the plurality of virtual resources or by assigning the plurality of real resources to the single virtual resource according to a utilization rate of the CPU, a utilization amount of the memory, or a utilization rated of the communication network, the software management unit assigns the real resources to the virtual resources in conformity with the priority of the software set as the policy data.
