The IESG has approved the following document: - 'Requirements for pNFS Layout Types' (draft-ietf-nfsv4-layout-types-13.txt) as Proposed Standard This document is the product of the Network File System Version 4 Working Group. The IESG contact persons are Mirja Kühlewind and Spencer Dawkins. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-nfsv4-layout-types/ 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. Personnel Spencer Shepler (NFSv4 WG co-chair) is the document shepherd Spencer Dawkins is the Responsible Area Director.
