Setting up NFS/RDMA
===================

Overview
========

This document describes how to install and setup the Linux NFS/RDMA client
and server software.

The NFS/RDMA client was first included in Linux 2.6.24. The NFS/RDMA server
was first included in the following release, Linux 2.6.25.

In our testing, we have obtained excellent performance results (full 10Gbit
wire bandwidth at minimal client CPU) under many workloads. The code passes
the full Connectathon test suite and operates over both Infiniband and iWARP
RDMA adapters.

Getting Help
============

If you get stuck, you can ask questions on the
nfs-rdma-devel@lists.sourceforge.net mailing list.

Installation
============

These instructions are a step by step guide to building a machine for
use with NFS/RDMA.

- Install an RDMA device

  Any device supported by the drivers in drivers/infiniband/hw is acceptable.

  Testing has been performed using several Mellanox-based IB cards, the
  Ammasso AMS1100 iWARP adapter, and the Chelsio cxgb3 iWARP adapter.

- Install a Linux distribution and tools

  The first kernel release to contain both the NFS/RDMA client and server was
  Linux 2.6.25  Therefore, a distribution compatible with this and subsequent
  Linux kernel release should be installed.

  The procedures described in this document have been tested with
  distributions from Red Hat's Fedora Project (http://fedora.redhat.com/).

- Install nfs-utils-1.1.2 or greater on the client

  An NFS/RDMA mount point can be obtained by using the mount.nfs command in
  nfs-utils-1.1.2 or greater (nfs-utils-1.1.1 was the first nfs-utils
  version with support for NFS/RDMA mounts, but for various reasons we
  recommend using nfs-utils-1.1.2 or greater). To see which version of
  mount.nfs you are using, type:

  .. code-block:: sh

    $ /sbin/mount.nfs -V

  If the version is less than 1.1.2 or the command does not exist,
  you should install the latest version of nfs-utils.

  Download the latest package from: https://www.kernel.org/pub/linux/utils/nfs

  Uncompress the package and follow the installation instructions.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
