The Distributed Systems Group (DSG) of SCD provides, maintains, and administers the necessary computer service infrastructure for the NCAR community to conduct daily computational activities. Examples of such service infrastructure are the NCAR electronic mail service, both Internet and Intranet World Wide Web (WWW) servers, and Domain Name Service (DNS) for NCAR. Most of these services are provided transparently to NCAR users. In addition, DSG supports and administers interactive servers on which to conduct daily activities (e.g., e-mail, text editing, MSS access), gateway servers that process 50% of supercomputer job submittals and MSS activity, library access and queries, and computational service (e.g., Computational Science Section HPC test server). The provision of these services is an ongoing, year-to-year activity for DSG, which continued these activities through FY1999.In addition to continuing to provide the above organization-wide services, DSG's focus for FY1999 was on the following primary areas:
- Consolidating services onto fewer servers and reduction of inter-machine dependencies
- Installation of Year-2000-compliant systems and applications and performing Year 2000 testing and tolerance insurance on mission-critical systems
- Increase storage capacity and memory on servers and workstations
- Increase the number of high-availability and fault-tolerant server and storage configurations
- Provide servers with faster network connectivity
- Integrate distributed system management tools
- Running PC applications on UNIX desktops
- Enhance user security (e.g., ssh shell)
- Continue to phase out obsolete servers and workstations
