Broadcom N1200G 200GbE OCP 3.0 Adapter

The Broadcom N1200G is a single-port OCP NIC 3.0 Small Form Factor Ethernet adapter built on Broadcom's Thor (BCM57508) controller, delivering up to 200Gbps through one QSFP56 cage over 4x56G PAM4 SerDes lanes that also auto-negotiate down to 100/50/40/25/10GbE. The card connects to the host over a PCIe Gen4 x16 edge connector compliant with the OCP 3.0 SFF-TA-1002 mechanical and 4C+ pinout specifications for tool-less, front-serviceable installation. It carries the full Thor feature set: RDMA over Converged Ethernet (RoCEv2), the TruFlow engine for line-rate Open vSwitch offload, SR-IOV virtual-function support, multi-host connectivity so several CPUs can share the adapter, and a silicon Root-of-Trust with secure boot and attestation for platform integrity. TruManage rounds out standards-based system management for data-center-scale deployments. The N1200G suits enterprise and cloud servers that need 200GbE-class bandwidth in a compact, front-pluggable OCP form factor.
