Technical Summary

       This Internet-Draft introduces the Flex File Layout Type
       to extend parallel NFS (pNFS).  This layout type allows for
       the control protocol to be defined in another I-D or
       to be the NFS storage protocol.  This I-D details the
       interaction of the new layout type with both NFSv4.1
       and NFSv4.2 metadata servers. It also introduces
       client-side mirroring for the replication of files.

Working Group Summary

       The WG had no major issues during the WGLC. The new layout
       type is implementable. There are several client and server
       implementations already interoperating based on the I-D.

Document Quality

       This Internet Draft reviews and clarifies the requirements
       for creating a new Layout Type.  It uses the three existing
       Layout Type specification as case studies to show that the
       requirements were issues considered during the creation of
       earlier Layout Types.  I.e., it captures the relevancy of
       the requirements.  The content of this document has received
       quality feedback and review throughout its life.
