Data storage hierarchy with shared storage level.

摘要

A data storage hierarchy which inherently allows for a level 1 storage file to be uniquely identified across an entire network is disclosed. A directory naming convention is employed which includes an internal identifier and a name for each subdivision of the network. Because each file can be uniquely identified across the network, a single level 1 storage space in a file space, or a directory therein, can be used for the entire network. Also, because of the inherent uniqueness of the naming system, common DASD control files otherwise required to map between level 1 storage files and their level 0 source files can be eliminated.
