InfiniBand uses a switched fabric topology with native transactions, channels and RDMA, and it’s not routable. Ethernet is a kind of lowest common denominator that everything eventually devolves to. InfiniBand does a better job as interconnect for a compute cluster. Ethernet has the advantage of using well-understood routable protocols with standardised programming interfaces.
