  1. Data services and computing

  2. Computing reality • We tend to be dealt the computing environment in which we must operate. • Few of us have enough influence to steer the direction of central computing on our campus. • Thus, we try to match our computing needs with the resources provided locally.

  3. Match to level of service Develop a computing strategy that identifies • the hardware, • the software, and • the network connectivity needed to support the level of data service you are providing now and will be in the near future.

  4. Strategic factors • Desktop computing power • hardware • fastest affordable processor • largest affordable hard drive • largest affordable monitor • removable media drives support

  5. Strategic factors • Desktop computing power • the software it should support • metadata tools • statistical software • network tools • compression utilities

  6. Strategic factors • Large quantities of disk space on a fast system • uncompressing files • unpacking files • package and compress files

  7. Strategic factors • Access to at least one fast processing machine with statistical software • powerful Unix workstation • handle larger-scale problems

  8. Strategic factors • Mass storage that supports multiple-user access to files and preferably multiple-system access • distributed file system • institutional repository

  9. Strategic factors • Support software for data services • statistical packages • metadata support • communication tools • web tools • blogs/wikis • training tools

  10. Strategic factors • Network connectivity permitting high-speed file transfers • off and on campus transfer • may require using services elsewhere on campus

  11. Implementation strategy • System administration takes a lot of time! • think twice about becoming your own system administrator

  12. Implementation strategy • Purchase compatible computing equipment • to receive maintenance support • simplifies the sharing of peripheral devices

  13. Implementation strategy • Investigate local computing support • possibly a centralized high performance computing service or compute grid • site licenses for software

  14. Implementation strategy • Align with local institutional repository services and digital preservation initiatives • introduce data to the planning of your institutional repository

  15. Data infrastructure models • Data centres • The data centre is part of the instrumentation infrastructure. • e.g., the Large Hadron Collider • Data repositories • The repository is part of a specific institution’s larger stewardship mandate for digital resources. • e.g., Odesi in Scholar’s Portal • Domain archives • Domain archives are institutions established explicitly to preserve and provide access to a domain’s data. • e.g., the ICPSR and the UKDA
