The Project

Mission Statement

• To openly design and develop a NFSv4.1 parallel NFS (pNFS) implementation for OpenSolaris
• To verify and provide feedback to the IETF NFSv4 working group about the NFSv4.1 specification
• To understand the impacts and requirements of NFSv4.1 pNFS for OpenSolaris

The Project Gate

• Our project gate is at nfs41-gate
• It is available for Mercurial download at ssh://anon at hg dot opensolaris dot org/hg/nfsv41/nfs41-gate

Downloads

• Go to the Downloads page for our current installable bits.

Mailing List

• Don't forget to sign up for the NFSv4.1 project mailing list.

Proposed Deliverables

• Look at the NFS version 4.1 pNFS: Project Logistics page for an outline of the deliverables.

The Technology

What is NFSv4.1?

• NFSv4.1 is the first minor version of NFSv4. The major extensions included in NFSv4.1 are Sessions, Directory Delegations and parallel NFS.

What is pNFS?

• The pNFS protocol allows us to separate a NFS file system's data and metadata paths. With a separate data path we are free to lay file data out in interesting ways like striping it across multiple different file servers. For more information, see the NFSv4.1 specification.

Links

• Summary (including slides) of the September 2006 FROSUG Meeting where pNFS was presented.
• NFSv4.1 Specification – Draft 29

Status

Current Information

• We will be testing the Solaris pNFS client and server at the next interoperability event, February 2009 ConnectAthon hosted by Sun in San Jose, CA.

Past Information

• We tested the Solaris pNFS client and server at the interoperability event, the September 2008 Bake-a-thon (BAT), hosted by the NFS team in Austin, Texas.

• We tested the Solaris pNFS client and server at the interoperability event, the May 2008 ConnectAthon hosted by Sun and NetApp in San Jose, CA.

• The pNFS client and server was taken to both the June 2007 Bakeathon in Austin, Texas and the October 2007 Bakeathon in Ann Arbor, MI.

• The pNFS client prototype was taken to the NFSv4 Bakeathon held in Ann Arbor, MI, Sept. 11-15, 2006. The OpenSolaris pNFS client was able to successfully do parallel I/O against all of the files-based pNFS servers in attendance.
