Dual-port 200GbE server adapter

The Broadcom BCM957608-N2200GQP00 is a dual-port 200 Gb/s Ethernet network interface card built for AI, cloud and high-performance computing clusters. It uses a PCIe 5.0 x16 host interface and two QSFP112 cages to deliver 400 Gb/s total bandwidth. The OCP 3.0 form factor targets rack-scale deployments that need standards-based RoCEv2 with hardware congestion control.

Installation and common issues

The card installs into a PCI Express 5.0 x16 slot and auto-negotiates link rates of 32, 16, 8, 5 or 2.5 GT/s with lane configurations down to x1. QSFP112 modules must match the 100/50G PAM4 or 25G NRZ SerDes capability; mismatched optics will prevent link-up. Secure Boot, SPDM attestation and OCP Secure Recovery require platform firmware support to function.

Sustained-load behaviour

Eight SerDes lanes run at 100/50G PAM4 or 25G NRZ to maintain 400 Gb/s aggregate throughput under continuous AI/ML and storage traffic. Hardware-based DCQCN congestion control and Peer Memory Direct offloads keep latency stable during prolonged bursts. IEEE-1588v2 timestamping and automated configuration assist deterministic performance in multi-node environments.

Questions about this item

How do I confirm the card is running at the full 200 Gb/s per port after installation?

Check the link status in the OS or switch CLI; each QSFP112 port should report 200 GbE with auto-negotiation and IEEE-1588v2 active.

What comes in the box and what must I source separately for a working link?

The card ships alone; you must add two QSFP112 transceivers or direct-attach cables and a PCIe 5.0 x16 slot.

Which port mode should I select — 1×400 GbE or 2×200 GbE — for my workload?

Choose 2×200 GbE when you need two independent 200/100/50/25 GbE links; choose 1×400 GbE for a single 400 GbE pipe.
