Ballot Text

Technical Summary
   Motivation for the application of Remote Direct Memory Access
   to the NFS protocols is described. NFS implementations
   historically incur significant overhead due to data copies on
   end-host systems, as well as other processing overhead. The
   potential benefits of RDMA to these implementations are
   explored, and the reasons why RDMA is especially well-suited to
   NFS and network file protocols in general are evaluated.
Working Group Summary
   There is consensus in the WG to publish this document.
Protocol Quality
   As the Informative References demonstrate, this work has drawn
   on a variety of work in academia and industry and
   appropriately motivates the appropriate use of RDMA
   technologies for protocols such as NFS.
