We are planning to get a ConnectX-6 200G (something like MCX613106A-VDAT). Before we get a 200G QSFP56 switch, can we connect this card to a switch with only QSFP28 ports?
Can we simply plug a QSFP28 fiber from the switch to the NIC?
Hello Baptiste,
Thank you for posting your inquiry on the NVIDIA Networking Community.
The following link will provide you the information regarding the current supported cables and link-operability based on the ConnectX-6 network adapter → https://docs.mellanox.com/display/ConnectX6Firmwarev20311014/Firmware+Compatible+Products
From here, you will able to determine the supported cables and switch port speed.
Thank you and regards,
