Abstract
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.
