Adam,

Thanks, this is the avenue i was heading down, I just didn't have all
the config details worked out in my head.  Any config related info you
can pass along would be appreciated.

All,

I've heard of the mellanox solution, but I have to shoe horn this into
an existing machine where purchasing more hardware isn't an option at
the moment.  Besides I'd rather cobble up some wonky solution then
just purchase something off the shelf...  i'm not a docker loving
millennial... :)
