</div>To see which device you have, type the following command in your linux console:<br>
<br>
lspci | grep Mellanox<br>
<br>
For ConnectX (mlx4), you will see:<br>
InfiniBand: Mellanox Technologies: Unknown device 634a (rev a0)<br>
(lspci has not caught up with us yet).<br>
<br>
For Arbel (InfiniHost III), you will see either:<br>
InfiniBand: Mellanox Technologies MT25208 InfiniHost III Ex HCA (rev a0)<br>
<br>
or, if you are running your arbel in Tavor compatibility mode:<br>
<br>
InfiniBand: Mellanox Technologies MT25208 InfiniHost III Ex (Tavor compatibility mode) (rev 20)<br>
===========<br>
If your installed HCA is a ConnectX, you should use the module parameters for mlx4.<br>
If your installed HCA is an InfiniHost III, you should use the module parameters for ib_mthca.<br>
