Abstract

An exemplary management system identifies, based on first information indicating a job net defining an execution order of jobs executed by the host computer, jobs having possibility to be executed simultaneously at the job net. The management system identifies, based on second information indicating an execution content of each of the jobs, storage areas at the host computer for storing data of the jobs having possibility to be executed simultaneously. The management system identifies, based on third information indicating an allocation relation between the data storage areas of the host computer and resources of the storage apparatus, a resource of the storage apparatus allocated to each of the identified storage areas. The management system determines a physical resource of the storage apparatus, allocated to at least two of the storage areas of the identified storage areas, has possibility to be used simultaneously by at least two jobs.
