Storage for Digital Copies

To give us the greatest possible flexibility in developing the project, we decided to form the server out of two interlinked computer systems, a standard IBM System 390 with the OS/390 Open Edition version as the operating system and a standard IBM RS/6000 System with the AIX version of the UNIX operating system. Both these components may be incrementally grown as the project's server requirements increase. Both systems are relatively commonplace at academic sites. Although only one system pair is needed in this project, it is likely that eventually two pairs of systems would be needed for an effort on the national scale. Such redundancy is useful for providing both reliability and load leveling.
