Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN adapter (MCX623405AN-VDAN) is delivered in the OCP 2.0 mezzanine form factor rather than a standard PCIe bracket card, letting it slot directly into OCP-compliant server designs common in hyperscale and cloud data centers. Built on the ConnectX-6 Dx (MT28928) ASIC and connected via a PCIe 4.0 x16 host interface, it provides a single 200Gb QSFP56 Ethernet port with hardware-accelerated RDMA over Converged Ethernet (RoCE v2), ASAP^2 offloads for virtual switch and packet processing (OVS/OVS-DPDK), and SR-IOV virtual function support for dense multi-tenant virtualization. This is the baseline OCP 2.0 SKU in the family, without the Secure Boot or inline Crypto offload options found on the AC OCP variant. It targets hyperscale and cloud operators standardized on the OCP 2.0 mezzanine spec who need 200GbE performance and offload capability with a compact, tool-less form factor optimized for high-density server deployment.
