COUPLING A USER FILE NAME WITH A PHYSICAL DATA FILE STORED IN A STORAGE DELIVERY NETWORK

摘要

A method of coupling a user file name to a physical data file stored within a storage delivery network, includes: assigning a logical file identification value (LFID) to a data file stored in one or more storage nodes and storing the LFID in a computer readable memory; storing in the computer readable memory a node identification value (Node ID) indicative of where the data file is stored among a plurality of geographically distributed storage nodes and associating the Node ID with the LFID; and storing in the computer readable memory a file name for the data file created by a user and associating the file name with the LFID, wherein the LFID correlates the file name with the Node ID transparently to the user and allows the user to access the data file using just the file name.
