Jeff mentioned in the video that only three of the ports can be used for RDMA. But it’s unclear where that limitation is coming from.

From my brief discussion with Exo/Apple, it sounds like that is just a limitation of this initial rollout, but it's not a hardware limitation.
Though, I am always leery to recommend any decisions be made over something that's not already proven to work, so I would say don't bet on all ports being able to be used. They very well may be able to though.
