Technical Summary
This Internet-Draft outlines high-level requirements for
the introduction of new Layout Types into parallel NFS
(pNFS). In RFC5661, the delineation between the requirements
for pNFS and the File Layout Type is not clear for all
readers. This I-D clarifies the responsibilities of a generic
Layout Type by examining all of the existing Layout Types,
not just the File Layout Type.
Working Group Summary
When discussing new proposed Layout Types, there was a lot
of confusion about the role of a Control Protocol between
the metadata server, the storage devices, and the clients.
The casting of the Control Protocol as a set of requirements
has reduced that confusion and has resulted in a broad
consensus to support this 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.
