1 Data services and computing

2 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. Computing reality

3 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. Match to level of service

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

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

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

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

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

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

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

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

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

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

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

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

16 Emerging data infrastructure Duration of access Institutional based Domain based Long-term trusted repository Mid-term digital repositories Immediateinternet

17 Examples Duration of access Institutional based Domain based Long-term NARA Scholars Portal ICPSR Genbank Mid-term DataStaR National Center for Ecological Analysis and Synthesis Immediate Local govt data Cross-national Time-series Data Archive
