Yeah they would need a breakout cable. And there’s no way in hell they can have a link of 40G via SFP+ to a 10G appliance.

Agreed that they can't get a 40G link when attaching to a 10G device, but the 40G QSFP can be split into 4 10G SFP+ connections instead

Also for whoever is curious, there’s 100G QSFP28 which has breakdown cables to 4x 25G SFP28, I’m not a networks guy but I think at that point it’s not Ethernet anymore but InfiniBand.
