Parallel NFS Flexible File Layout
RFC 8435, “Parallel NFS Flexible File Layout”, is a Proposed Standard document published in August 2018 by B. Halevy, T. Haynes. The canonical text is published by the RFC Editor.
Abstract
Parallel NFS (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 that allows the use of storage devices that require only a limited degree of interaction with the metadata server and use already-existing protocols. Client-side mirroring is also added to provide replication of files.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
