Overview

The Mellanox charm installs the Mellanox Ethernet driver software and configures it to enable maximum performance for a Mellanox Ethernet adapter. The charm will also program the adapter firmware if the adapter is standard. If it is not standard one will need to program it outside the charm for that you can download the Mellanox Firmware Tool at the following URL Mellanox Firmware tools.

Usage

Deploy the Mellanox charm from the Juju GUI or the command line:

juju deploy mellanox

Before the Mellanox software can be installed one must explicitly accept the Mellanox software license (that can be found in the Mellanox_license.txt in the charm directory). To accept the Mellanox license, set the configuration option accept-mellanox-license to True. Changing the configuration options can be done from the Juju GUI or from the command line:

juju set mellanox accept-mellanox-license=True

If the license is not accepted the Mellanox software will not be installed.

Intel hardware (x86)

The Mellanox charm can be configured to run on x86 hardware. To run on Intel hardware set theofed-file and md5sum configuration values appropriately. Go to "Downloads" section on the Mellanox product webpage to find the version and architecture of software that you wish to install. For example:

juju set mellanox ofed-file=MLNX_OFED_LINUX-2.3-2.0.0-ubuntu14.04-x86_64.tgz
juju set mellanox md5sum=0985c1a6d991b1169e32bebe2c146980

Power hardware (ppc)

The Mellanox charm defaults to the PowerPC version in config.yaml file. To change the version of popc64le Mellanox software installed you must change the ofed-file and the md5sum configuration options:

juju set mellanox ofed-file=MLNX_OFE enteredD_LINUX-(version)-ubuntu14.04-ppc64le.tgz
juju set mellanox md5sum=(md5sum of the version)

Go to "Downloads" section on the Mellanox product webpage select the version and Ubuntu 14.04 to find the md5sum of each file.

Deploy using a configuration file

Alternately a configuration YAML file can be passed on deployment. Create a YAML file that contains the following content:

mellanox:
  accept-mellanox-license: True
  ofed-file: "MLNX_OFED_LINUX-2.3-2.0.0-ubuntu14.04-x86_64.tgz"
  md5sum: "0985c1a6d991b1169e32bebe2c146980"

Then deploy the Mellanox charm with this configuration file:

juju deploy mellanox --config mellanox_x86.yaml

Relate the Mellanox charm to a container charm

Finally, the Mellanox charm must be related to another charm. The Mellanox charm is what is known as a subordinate charm, meaning it does not get its own container (or machine). For this charm to function correctly it must be related to a container (machine) with a Mellanox Ethernet adpter.

juju add-relation mellanox <target-charm>

It is recommended to reboot the server after running the charm.

Known Limitations and Issues

The Mellanox software requires a Mellanox Ethernet adapter to fully operate.

Per server the configuration can change and additional tuning is required if you can not get the full line performance measurements (e.g. ~40GbE).
