Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN MCX623435AN-VDAB is a single-port 200GbE OCP Spec 3.0 network adapter built on the ConnectX-6 Dx ASIC (MT28928A0-XCCF-CE), NVIDIA's cloud-optimized member of the ConnectX-6 family. Delivering line-rate 200 Gb/s Ethernet connectivity through a single QSFP56 port over a PCIe 4.0 x16 host interface, the card is engineered for hyperscale and enterprise data centers that need maximum throughput per slot alongside advanced offload capabilities. It supports RDMA over Converged Ethernet (RoCE v2) for low-latency, CPU-efficient data movement, along with the ConnectX-6 Dx stateless offload set — including SR-IOV virtualization, NVMe-oF acceleration, and QoS-aware traffic management. Packaged in the OCP 3.0 small form-factor with a thumbscrew (pull-tab) bracket, the MCX623435AN-VDAB slots directly into OCP-compliant server and switch baseboards, making it well suited for cloud service providers and enterprises standardizing on the OCP 3.0 mechanical specification for next-generation 200GbE fabrics.
