ABSTRACT:

Oak Ridge Leadership Computing Facility (OLCF) has deployed multiple
world-class parallel file systems to support its compute, data analysis, and
visualization platforms. After deployment, OLCF has continued to hone operating
strategies for these systems in response to rapidly changing technologies
and user demands. OLCF's file systems have also served as test platforms for new
file system features; as technology evaluation platforms for I/O strategies and
benchmarks; and as hubs for data storage and transfer for OLCF users. During
this process, OLCF has acquired significant expertise in the areas of data
storage systems, file system software, technology evaluation, benchmarking, and
procurement 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.
