You can connect the InfiniBand-Ethernet gateway switch directly to a 40 Gb Ethernet switch in your datacenter. Alternatively, you can use a 40 Gb-to-10 Gb x 4 fan-out cable to provide four 10 Gb connections from a single switch port. Note that the connectors on the 4 x 10 Gb fan-out cable are direct attach twinaxial connections, and the datacenter LAN switch must support that type of connector.
