Introduction
============
OpenOnload(R) is a high performance user-level network stack, which
delivers absolutely the best performance to applications using the BSD
sockets API. Please see www.openonload.org for more information.
EnterpriseOnload is a version of OpenOnload that includes an extended test
cycle, guaranteed support from Solarflare, bug fixes and a defined service
level agreement.
OpenOnload and EnterpriseOnload are licensed under the GNU General Public
License (Version 2, June 1991). See the LICENSE file in this distribution
for details.
Supported platforms
===================
Linux kernels from 2.6.18. ia32 and amd64/em64t processor architectures.
When using 64-bit kernels, both 32-bit and 64-bit applications are
supported.
Onload supports Solarflare SFC4000 and SFC9000 network controller chips,
including the following network adapters:
SFN7142Q
SFN7122F, SFN7322F
SFN5122F, SFN5322F
SFN6122F, SFN6322F
SFN5812H, SFN5814H
SFN5802K
SFN5121T
If you are interested in trying or buying Solarflare network adapters,
please contact <[email protected]>.
Documentation
=============
The Onload User Guide is available to customers with supported cards. You
can register and download a copy from: https://support.solarflare.com/.
You may also find the Solarstorm User Guide useful -- it is available from
the same place.
Quick start
===========
The following command will build and install the Onload drivers into
system directories (as root):
<top>/scripts/onload_install
You may need to reload the drivers if you have drivers loaded already:
onload_tool reload
Or to load the Onload and sfc drivers if none are loaded:
modprobe sfc
You may need to configure your ethernet interface with an IP address using
the standard tools. Please see the documentation that comes with your
Linux distribution for details.
To accelerate an application with the Onload user-level transport, simply
invoke the application on the command line as normal, prepended with
"onload".
ie. Instead of:
netperf -t TCP_RR -H myserver
do this:
onload netperf -t TCP_RR -H myserver
and tuned for best latency:
onload -p latency netperf -t TCP_RR -H myserver
Configuration and tuning
========================
Onload takes many configuration settings directly from the kernel stack.
In addition, there are a number of configuration and tuning options that
can be set via environment variables. See the Onload User Guide for
details.
You can get detailed descriptions of the configuration options in the
version of Onload that you are using by running the following command:
onload_stackdump doc
