We are planning to connect a QSFP28 NIC to an SN4600 switch with QSFP56 ports, but I have come across conflicting information online.
Do these two different technologies work together? If they do, is it appropriate to use a QSFP56 transceiver on the QSFP28 NIC, or should we use a setup where the NIC side remains QSFP28 and the switch side uses QSFP56?
