NVIDIA Mellanox ConnectX-4 Lx EN MCX4411A-ACAN OCP 2.0

The NVIDIA Mellanox ConnectX-4 Lx EN MCX4411A-ACAN is a single-port 25 Gigabit Ethernet adapter in the OCP 2.0 mezzanine form factor, providing baseline ConnectX-4 Lx connectivity for hyperscale and OEM server platforms without the added UEFI or Host Management options carried by sibling SKUs. It pairs a PCIe 3.0 x8 host interface with one SFP28 port capable of 25Gb/s, and offloads RDMA over Converged Ethernet (RoCE v2) in hardware for low-latency, low-CPU networking. This SKU is also distributed under Lenovo OEM part numbers (SN30M07759, 01KR933), reflecting its use as a qualified mezzanine NIC in Lenovo server platforms alongside its NVIDIA channel availability. Built on the single-chip MT27712A0-FDCF-AE controller, the ACAN variant is a cost-focused option for deployments that need standard OCP 2.0 25GbE RoCE connectivity without additional boot or management firmware features, while remaining electrically and functionally consistent with the rest of the ConnectX-4 Lx OCP family.
