I currently have a The BlueField-3 DPU OPNs 900-9D3B6-00CC-EA0 Single-port QSFP112 HOW TO CONNECT MQM8790-HS2F QSFP56 switch
Can qsfp112 be directly connected to QSFP56 or QSFP28? What kind of cables do I need to use?
If you are an official, please give me an accurate answer.
Yes, it can connect to QSFP56/QSFP28 cable. The BF3 DPU (900-9D3B6-00CC-EA0) works with 100GbE/HDR 100 IB. It uses QSFP 112 port but can work with QSFP56 / QSFP28 cable.
There are many optional copper/optical cables available. Here is a reference:
