The IESG has received a request from the Network File System Version 4 WG (nfsv4) to consider the following document: - 'Parallel NFS (pNFS) Flexible File Layout' <draft-ietf-nfsv4-flex-files-15.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 2018-01-16 (this date has been extended to accommodate year-end holidays). 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 The Parallel Network File System (pNFS) allows a separation between the metadata (onto a metadata server) and data (onto a storage device) for a file. The flexible file layout type is defined in this document as an extension to pNFS which allows the use of storage devices in a fashion such that they require only a quite limited degree of interaction with the metadata server, using already existing protocols. Client-side mirroring is also added to provide replication of files. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-nfsv4-flex-files/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-nfsv4-flex-files/ballot/ No IPR declarations have been submitted directly on this I-D.
