TITLE:
Exporting Parallel File Systems in a Scalable Manner with pNFS
ABSTRACT:
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.
BIO:
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.
