Large Synoptic Survey Telescope Data Challenge
Presenter: Darren Adams (NCSA)
PI: Tim Axelrod (University of Arizona)
The ECSS team has collaborated with the Large Synoptic Survey Telescope (LSST) project in evaluating the Research and Education Data Depot network (REDDnet) project. LSST researchers are interested in ways to make very large datasets available to researchers in geographically distant locations. The REDDnet project has devised a system of storage "depots" that are geographically distributed. Using the Logistical Storage (Lstore) system, also developed at Vanderbilt, files can be stored, replicated and striped based on user-defined policies. Polies can be created to emphasize fault-tolerance, performance, and/or geographic availability. The ECSS collaboration included integrating the LStore server with the NCSA Mass storage system and the loading of data sets from recent LSST data challenges. New featuresi ncluding FUSE filesystem interface capabilities may make REDDnet a viable choice for the LSST team.
