Internet Engineering Task Force (IETF) S. Shepler, Ed. Request for Comments: 5661 Storspeed, Inc. Category: Standards Track M. Eisler, Ed. ISSN: 2070-1721 D. Noveck, Ed. NetApp January 2010 Network File System (NFS) Version 4 Minor Version 1 Protocol Abstract This document describes the Network File System (NFS) version 4 minor version 1, including features retained from the base protocol (NFS version 4 minor version 0, which is specified in RFC 3530) and protocol extensions made subsequently. Major extensions introduced in NFS version 4 minor version 1 include Sessions, Directory Delegations, and parallel NFS (pNFS). NFS version 4 minor version 1 has no dependencies on NFS version 4 minor version 0, and it is considered a separate protocol. Thus, this document neither updates nor obsoletes RFC 3530. NFS minor version 1 is deemed superior to NFS minor version 0 with no loss of functionality, and its use is preferred over version 0. Both NFS minor versions 0 and 1 can be used simultaneously on the same network, between the same client and server. Status of This Memo This is an Internet Standards Track document.
