摘要:
The invention relates to a method of virtualizing a plurality of network storages into a single-view file system for a client and obtains information about an object's storage location without inquiring of a resource manager. The method determines a network storage that should store an object based on a hash value generated from a logical identifier for the object to be accessed. While accessing the object, the method computes the hash value for the object's logical identifier to determine a network storage that should process an access request. Consequently, the method eliminates the need to inquire the object's storage location when the access request is issued. Further, the method eliminates the need to maintain the object's storage location when the number of servers is increased or decreased, thus providing easy management.
