Which cable to connect ConnectX-7 with Broadcom P2100G?

Infrastructure & Networking Adapters and Cables Ethernet Adapter Cards

Hi Everyone,

We’ve purchased a new storage server that comes with a MCX713106AS-VEAT 200Gbe ConnectX-7 card. We also have a system with a Broadcom P2100G 100Gbe card that has gone unused until now. The ConnectX-7 card has dual QSFP112 ports on it, while the P2100G has dual QSFP56 ports. Would we be able to connect the two using a single QSFP56 cable? Or would we need a QSFP112 to QSFP56 splitter to connect the two? We’d like to be able to connect the two so that we can utilize the full bandwidth.

Regards,
