Mellanox's 4-to-1 breakout cables are for making a single switch port into 4 switch ports, but I'd rather breakout a single QSFP28 NIC port into 4 SFP28 that I can then directly attach to SFP28 NIC ports from separate server.

Seems like the CX4 cards won't work with this, which is a shame because their prices seem to be getting better on eBay.
