The IESG has received a request from the Network File System Version 4 WG (nfsv4) to consider the following document: - 'Requirements for pNFS Layout Types' <draft-ietf-nfsv4-layout-types-09.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-02-23. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document defines the requirements which individual pNFS layout types need to meet in order to work within the parallel NFS (pNFS) framework as defined in RFC5661. In so doing, it aims to clearly distinguish between requirements for pNFS as a whole and those specifically directed to the pNFS File Layout. The lack of a clear separation between the two set of requirements has been troublesome for those specifying and evaluating new Layout Types. In this regard, this document updates RFC5661. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-nfsv4-layout-types/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-nfsv4-layout-types/ballot/ No IPR declarations have been submitted directly on this I-D.
