Product Description

The NVIDIA Mellanox ConnectX-5 MCX566A-CDAI is a ConnectX-5 Ex Ethernet Networking (EN) adapter built in the OCP 3.0 small form-factor, designed for tool-less deployment in hyperscale and cloud server chassis. It provides two 100GbE QSFP28 ports over a PCIe 4.0 x16 host interface, doubling the available host bandwidth compared to earlier PCIe 3.0 ConnectX-5 cards and allowing both ports to run at full line rate concurrently. Built around the MT28808A0-FCCF-CE controller, the card supports RDMA over Converged Ethernet (RoCE v2) for CPU-offloaded, low-latency networking, along with NVMe-oF storage acceleration, embedded switching for SR-IOV multi-tenant environments, and stateless offloads for overlay networks. The OCP 3.0 form factor with its standardized connector and hot-swap-friendly bracket simplifies high-density rack deployment, making the MCX566A-CDAI a strong fit for hyperscale, cloud, and software-defined storage infrastructure that demands 100Gb Ethernet throughput without occupying a standard PCIe slot.
