Long-term preservation Members in the partnership will each operate a grid node containing at least 50 terabytes of storage capacity to house the project’s entire collection, making multiple copies available across the country. At each partner site, Chronopolis will use existing high-speed educational and research networks as well as mass-scale storage infrastructure, including storage space, servers, and front-end machines. Each site will use its own brand of hardware, enabling Chronopolis to provide long-term data preservation that does not rely on just one brand. The project will also use data management software already installed at the partner institutions to create the grid and monitor the flow of information between the partner sites. Institutions providing data for Chronopolis include the University of Michigan’s Inter-University Consortium for Political and Social Research, the University of North Carolina Geospatial Data Archiving Project, the California Digital Library, and the UC San Diego Scripps Institute of Oceanography. By tracking the data in Chronopolis every step of the way, the partnership can not only guarantee the information remains safe, but can also guarantee its authenticity and availability to researchers for years to come, says SDSC manager David Minor. “We have the capacity for a much larger set of data than is typically worked with in the preservation community,” Minor says. “Not only are we looking at how to house that much data, but how can we move it across the country as quickly and effectively as possible so that each different copy is safe and up to date with all of the other copies.”
