Product Description

The NVIDIA Mellanox ConnectX-6 Dx EN network adapter MCX623432AN-ADAB is a dual-port 25GbE OCP 3.0 form-factor smart network interface card that pairs ConnectX-6 Dx-class silicon with an OCP 3.0 Small Form Factor (SFF) module for tool-less installation in OCP-compliant server chassis. The card connects via a PCIe 4.0 x16 host interface — double the lane count of the standalone ConnectX-6 Dx SFP28 cards in this catalog — to dual SFP28 cages supporting RoCE v2 RDMA, giving it additional headroom for multi-queue, multi-tenant and storage-offload workloads even in this base configuration. This variant ships without hardware Secure Boot or inline Crypto offload, keeping cost and power draw to a minimum for large-scale, cost-sensitive server fleet rollouts. Built on the MT28928A0-XCCF-CE controller, the MCX623432AN-ADAB is intended for hyperscale and enterprise OCP server platforms that need ConnectX-6 Dx-class Ethernet performance with OCP 3.0 serviceability. It is supported by NVIDIA's OFED, WinOF-2 and DOCA driver stacks across Linux, Windows and VMware environments.
