iRODS at the ASDC - Performance Results and Lessons Learned

The Atmospheric Science Data Center is in the process of upgrading mechanisms by which its data can be discovered, accessed and understood. One mechanism which shows particular promise is Integrated Rule-Oriented Data System. ASDC has conducted testing of iRODS as a data discovery and delivery mechanism and has found excellent performance. The ASDC then federated their implementation with the NASA Center for Climate Simulation and established a production-level presence, making all data products available through this mechanism. We present lessons learned from its deployment, including the automation of the population of the directory system (iCAT) from ASDC's ontology. Further experiments to evaluate data delivery to Amazon Web Services have been conducted and are described.
