The HADES file server
Hartmut Reuter · 2002
HADES (Heidelberg Automatic Data management and Editor System), a file server for the IBM/370 world under the operating systems VM or MVS, is described. It may be used from CMS, MVS batch, and TSO directly and from UNIX systems via FTP and NFS. HADES has its own data management system independent of the host operating system. It uses automatic data migration onto tape to save disk space and keeps two tape copies of each file. Since there are nearly no limitations on file size and number of files, HADES files can be used as easily as bitfiles. Some of the requirements defined in the IEEE Reference Model are fulfilled by an automatic backup process for CMS minidisks that was designed on top of the HADES file system.>
