The present invention relates to a method for allocating volumes having a suitable physical location relationship based on a method of use of files by applications. When an application management unit receives an application area expansion request, a distribution request table is created based on a preset distribution rule table and a file management table. The distribution rule table includes a flag indicating whether or not files stored on a logical disk for allocation, and existing files, may be stored on the same disk drive. A storage management unit selects, in consideration of the distribution request table, a logical disk having suitable physical attributes from unused logical disks satisfying basic conditions such as requested size and RAID configuration. The selected logical disk is allocated to the application.
A storage system comprising:
A management computer connected respectively to a primary computer on which at least one application program is executed, and a storage apparatus for storing a plurality of data used by the application program on one or a plurality of storage devices, and controlling allocation of storage areas to the application program, comprising:
A storage area allocation method for allocating storage areas comprising storage devices of storage apparatuses to application programs running on a primary computer, comprising the steps of:
