A new Request for Comments is now available in online RFC libraries. RFC 5532 Title: Network File System (NFS) Remote Direct Memory Access (RDMA) Problem Statement Author: T. Talpey, C. Juszczak Status: Informational Date: May 2009 Mailbox: tmtalpey@gmail.com, chetnh@earthlink.net Pages: 15 Characters: 36746 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-nfsv4-nfs-rdma-problem-statement-08.txt URL: http://www.rfc-editor.org/rfc/rfc5532.txt This document addresses enabling the use of Remote Direct Memory Access (RDMA) by the Network File System (NFS) protocols. NFS implementations historically incur significant overhead due to data copies on end-host systems, as well as other processing overhead. This document explores the potential benefits of RDMA to these implementations and evaluates the reasons why RDMA is especially well-suited to NFS and network file protocols in general.
