After deployment, OLCF has continued to hone operating=0Astrategies for these systems in response to rapidly changing technologies=0Aand user demands. OLCF's file systems have also served as test platforms for new=0Afile system features; as technology evaluation platforms for I/O strategies and=0Abenchmarks; and as hubs for data storage and transfer for OLCF users. During=0Athis process, OLCF has acquired significant expertise in the areas of data=0Astorage systems, file system software, technology evaluation, benchmarking, and=0Aprocurement practices. This paper provides an account of our experience and lessons learned in acquiring, deploying, and operating large, parallel file systems. We believe that these lessons will be useful to the wider HPC community involved in such activities.
