You'd need something like this, which you can jumper over to the 10G port.

Cable to break it out.
I believe that these (and the AOC option) require that the switch understand / supports splitting the 40G interface into 4x10s -- now, presumably Randy can figure that out for the Arcus, but it's disappointing how many devices *dont* support this. Actually, while we are discussing this, does anyone know of a current NIC which has 4 or more 10G ports? The Mellanox switches can channelize their ports (and they sell a cable for this), but the NICs don't support it... W

-- I don't think the execution is relevant when it was obviously a bad idea in the first place. This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants. ---maf
