  3. Novell Directory Services (NDS) and the Computing Infrastructure A real world example: Clemson University Division of Computing and Information Technology

  4. Background on Clemson IS Mission & Support Structure Userid Management Network Design Server & Network Access Public Access Labs Printing Electronic Mail Intranet Authentication Server Futures Agenda

  5. Background on Clemson Information Systems • Large Systems Background • Strong Development Shop • Mainframe and Open Systems Expertise • Departmental LANs ruled 90’s until NDS • NDS populated in Summer 1995 (36,000) • Departmental LANs gone. More centralized management of the network. • NDS is centerpiece of security and authentication.

  6. Mission and Support Structure • Mission • Defining groups • Support structure • Server strategy and management

  7. Mission & Support Structure

  8. Mission • Provide computing infrastructure. • Empower Users and Departments. • Provide guidance in selecting solutions based on industry standards. • Deploy solutions to meet the needs of institutional computing. • Provide user support and training.

  9. Defining Groups • Network Services - supports the physical network…routers, hubs, backbone • LAN Systems- supports application, group, and personal data servers. • Client Support Group (CSG) - supports faculty and staff via TSPs. • Systems Integration Group (SIG) - supports students and departmental labs.

  10. Defining (more) Groups • Computer Resources - assists with user account problems (DCIT sponsored). • College Consultants - DCIT sponsored person and college sponsored person(s) that help support the end users of the college. • Technology Support Provider (TSP) - supports faculty/staff end users • Help Desk - sponsored by DCIT to assist end users.

  11. Support Structure • Support is based on a four tier model. Problems 2 3 1 4 Computer Resources TSPs Network Services Faculty Staff Client Support College Consultant LAN Systems Students Systems Integration HelpDesk Resources

  12. Server Strategy & Management • Novell and NT servers maintained by Divison of Computing & Info Tech (DCIT). • DCIT provides hardware and Network Operating System (NOS). • DCIT administers backups. • DCIT performs user administration. • Group maintains data and security with help of a Tech Support Provider (TSP). • Virus Protection and Software Metering

  16. Userid Management • Automatic Userid System (AUS) • Automating user maintenance

  17. Network Design • Physical network design • Tree design • Every person has a place • Every group has a place • Partition design • Use dedicated "ROOT" servers for NDS replicas • Distribute network management • Login script design • Script design and management • Server timesync hierarchy

  18. Server and Network Resource Access • Personal storage • Personal data server configuration

  19. Server and Network Resource Access (cont.) • Collaborative storage • "Group servers" (faculty and staff) • "App servers" (students) • Group/App/Root server • Average configuration • Faculty/student collaboration • Faculty and Time Synchronization Protocol (TSP)/client support management • Collaborative storage and network bandwidth

  20. Public Access Labs • The virtual PC • Standard lab • Personal storage • Collaborative storage • "App Servers" (students) • Goals of the virtual PC paradigm • Evolution • How it happens to the user

  21. Public Access Labs (cont.) • Constructing the machine • Boot time events • Contextless login • The login script • Isitcool—fail-over applications server attachment • Loading the profile • Special mappings and events

  22. Public Access Labs (cont.) • Collaborative storage • "Group servers" (faculty and staff) • Collaborative storage • Logout • Problems • Network jacks
