All of our X520's don't care if you use Arista or Proline DAC cables (the two brands we have around).

If you are running Intel NIC(s) such as the X520-DA2 with 3rd party optics for something like DWDM, there are driver 
option flags for linux/windows, etc to permit the use of the optics. In deployments we've used various branded dac 
cables to connect Intel branded nics to cisco/arista/brocade, without issue.

As with any vendor, there is a work around procedure.

All other vendors, explicitly or silently, adopt the same approach.

I've heard from people running Intel NICs and HP switches, that this can't be turned off there. You run into very 
interesting problems when you're trying to use DAC cables between multi vendor.

Any pointers to how to turn this of on Intel NICs and HP switches?
