Product Description
The NVIDIA Mellanox ConnectX-6 MCX623432AS-GDAI is a 2-port 50GbE OCP3.0 network adapter built on the ConnectX-6 Dx EN silicon (MT28928A0-XCCF-CE). Delivering up to 50Gb/s per port over SFP56 connectors across a PCIe 4.0 x16 host interface, it combines RDMA over Converged Ethernet (RoCE v2) with hardware-based Secure Boot to protect firmware integrity from the moment the server powers on. The OCP 3.0 tall-bracket form factor, small-latch (AI) mechanical variant, is purpose-built for hyperscale and enterprise servers that require tool-less, hot-swappable network cards with a compact footprint. Combined with ConnectX-6 Dx's stateless offload engines for TCP/IP, RDMA, and virtualization, the MCX623432AS-GDAI is well suited for cloud infrastructure, AI/ML clusters, and software-defined storage environments where both performance and platform security are priorities. Its dual-port design also enables link aggregation and failover for mission-critical connectivity.
