Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN MCX623432AE-ADAB is a dual-port 25GbE OCP 3.0 SmartNIC built around the ConnectX-6 Dx MT28928A0-XCCF-CE controller. Connecting through a PCIe 4.0 x16 host interface and terminating in dual SFP28 cages, the adapter delivers line-rate 25 Gigabit Ethernet with RoCE v2 RDMA offload for low-latency, CPU-efficient networking in virtualized and cloud-native environments. As an OCP 3.0 small form factor (SFF) card, it slots directly into hyperscale and enterprise server chassis standardized on the Open Compute Project specification, simplifying tool-less, hot-swap serviceability. Hardware-enforced Secure Boot authenticates adapter firmware at every power-up, protecting the boot chain against tampering and unauthorized firmware execution — a control increasingly required in security-conscious data centers. Paired with ConnectX-6 Dx's programmable ASAP² hardware offload engine for virtual switching and storage acceleration, the MCX623432AE-ADAB suits software-defined networking, multi-tenant cloud infrastructure, and secure enterprise server deployments that demand both throughput and platform integrity.
