View source for Lustre intel: Setup Mellanox 10GB Modules for IEEL 2

* System was a centos 6.5 base image that was deployed with IML 
* Intel Agent repo was installed as part of the IML deployment 
* No mellanox drivers for the ethernet cards was provided


== Copy across the Mellanox Bundle ==
<syntaxhighlight>
  scp mlnx-en-2.3-1.0.0.tgz oss7:
  ssh oss7
  tar zxvf mlnx-en-2.3-1.0.0.tgz
</syntaxhighlight>

== Install the required dev tools ==
* Make sure you are running the lustre kernel (should be after IML is deployed)
<syntaxhighlight>
[root@oss7 ~]# uname -a
