CX7 network card can interconnect with other 400G Ethernet switches that support RDMA, but you need to pay attention to the following points:

  • The switch and the network card need to use suitable cables and transceivers, such as OSFP or QSFP112.
  • The switch and the network card need to use the same rate and frame size, such as 400 Gb/s and 4 KB MTU.
  • The switch and the network card need to configure the same RoCE v2 parameters, such as priority, flow control, congestion control, etc.
  • The switch and the network card need to ensure the stability and reliability of the network and avoid packet loss or retransmission that causes performance degradation.
