Product Description
The NVIDIA Mellanox ConnectX-6 MCX623432AN-GDAB is a 2-port 50GbE OCP3.0 network adapter built around the ConnectX-6 Dx EN controller (MT28928A0-XCCF-CE). It provides dual SFP56 ports operating at up to 50Gb/s each across a PCIe 4.0 x16 host interface, with RDMA over Converged Ethernet (RoCE v2) for low-latency, CPU-efficient data movement. Housed in the OCP 3.0 form factor with a screw-mount (AB) bracket, the card targets high-density hyperscale and enterprise server platforms that standardize on the OCP 3.0 mezzanine specification. ConnectX-6 Dx's stateless hardware offloads for TCP/IP, RDMA, and virtual switching reduce CPU load on the host, freeing compute resources for application workloads. This model is a strong general-purpose 50GbE OCP3.0 option for organizations building out cloud, virtualization, or storage-networking infrastructure without requiring the additional security or multi-host features found in other ConnectX-6 Dx SKUs.
