DataTree and UniTree: software for file and storage management

Abstract

The capabilities and advantages of DataTree and UniTree (hierarchical file- and storage-management systems for networked, multivendor computing environments) are discussed. DataTree is an advanced centralized MVS-based system; UniTree is a Unix-based file-server product. DataTree is the commercial version of the common file system (CFS) developed at the Los Alamos National Laboratory. The DataTree server platform is built upon the MVS operating system and serves client computers running on a wide variety of operating systems. UniTree is the commercial version of the file server developed and currently in production at the Lawrence Livermore National Laboratory. Unitree's compatibility with DataTree will enable it to provide a long-term migration option for DataTree/CFS users. The UniTree system includes utility programs for the conversion of DataTree directories to UniTree format. UniTree will process DataTree tapes directly, i.e. without having to rewrite them. >
