Parallel NFS Block/Volume Layout
RFC 5663, “Parallel NFS Block/Volume Layout”, is a Proposed Standard document published in January 2010 by D. Black, S. Fridella, J. Glasgow. It has since been updated by RFC 6688. The canonical text is published by the RFC Editor.
Abstract
Parallel NFS (pNFS) extends Network File Sharing version 4 (NFSv4) to allow clients to directly access file data on the storage used by the NFSv4 server. This ability to bypass the server for data access can increase both performance and parallelism, but requires additional client functionality for data access, some of which is dependent on the class of storage used. The main pNFS operations document specifies storage-class-independent extensions to NFS; this document specifies the additional extensions (primarily data structures) for use of pNFS with block- and volume-based storage. [STANDARDS-TRACK]
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.
