NVIDIA Mellanox ConnectX-5 MCX545A-CCAN OCP2.0

The NVIDIA Mellanox MCX545A-CCAN is a single-port 100 Gigabit Ethernet network adapter in the OCP 2.0 (Open Compute Project) form factor, part of the ConnectX-5 EN family and built on the MT28808A0-FCCF-EV controller. Like other OCP mezzanine cards, it mounts directly onto a compatible server motherboard's OCP 2.0 slot via a PCIe 3.0 x16 interface, preserving standard PCIe expansion slots for other components — a design favored in hyperscale and cloud-optimized server platforms. The MCX545A-CCAN provides hardware-accelerated RoCE v2 RDMA for low-latency, low-CPU-overhead networking across storage, cloud, and compute workloads. As a baseline OCP 2.0 SKU within the widely deployed ConnectX-5 generation, it offers a cost-effective, field-proven 100GbE connectivity option for organizations standardizing on OCP server hardware without requiring UEFI pre-boot network initialization.
