Exporting Parallel File Systems in a Scalable Manner with pNFS

Print, film, magnetic, and optical storage media produced approximately five exabytes of new information in 2002. Ninety-two percent of this information is stored on magnetic media, mostly in hard disks. Parallel file systems are the leading technology to provide scalable and secure access to this data, but limitations still exist. Most parallel file systems are limited to a single platform and do not interoperate with other file systems except through bandwidth limited technologies such as FTP, NFS and CIFS. Parallel NFS (pNFS) has the potential to provide platform independent access to parallel file systems while retaining all the benefits of NFSv4. The first prototype of pNFS exports the parallel file system PVFS2 and achieves
throughput that approaches that of PVFS2 and dramatically better than NFSv4. In this talk, I will give details of the implementation on the Linuxplatform and provide performance experiments demonstrating the potential of pNFS.

Dean Hildebrand is a Doctoral Candidate in Computer Science at the University of Michigan. His research focuses on file system enhancements in high performance computing under Peter Honeyman at the Center for Information Technology Integration.

Dean holds a M.S. from the University of Michigan and a B.S. from the University of British Columbia, both in Computer Science. He has worked as a software developer at several companies including IBM, Nortel Networks and Scotiabank. The work for this presentation was developed in the summer of 2004 at the Sandia National Laboratories.
