- <para>When using third-party network hardware with Lustre, the third-party modules (typically, the drivers) must be linked against the Linux kernel. The LNET modules in Lustre also need these references. To meet these requirements, a specific process must be followed to install and recompile Lustre. See <xref linkend="dbdoclet.50438210_27248"/>, for an example showing how to install Lustre 1.6.6 using the Myricom MX 1.2.7 driver. The same process can be used for other third-party network stacks.</para>
