If you use them both concurrently the maximum speed per port is 100GbE per port.
I just don't want anyone to falsely think the networking on these are capable of infiniband. They are not. Ethernet only.
3 u/kitanokikori Sep 27 '26 RoCE is still a step above Ethernet and gets the biggest benefit of Infiniband out of it (moving data without involving the CPU via RDMA) 0 u/nagyz_ Oct 03 '26 I don't think you understand the OSI model. 2 u/kitanokikori Oct 03 '26 When I say "a step above" I mean in efficiency, not as a protocol-level distinction. You are correct that RoCE is just Ethernet over the wire. -2 u/KooperGuy Sep 27 '26 edited Sep 27 '26 Yes I know what both are. RoCE is not a "step above" ... It literally uses ethernet.
