Product Description
The NVIDIA Mellanox ConnectX-6 Lx EN MCX631432AE-ADAB is a dual-port 25GbE OCP 3.0 SmartNIC built on the ConnectX-6 Lx MT28942A0-YCCF-AE controller, sharing the PCIe 4.0 x8 host interface and dual SFP28 connectivity of the ConnectX-6 Lx family while adding hardware crypto offload. RoCE v2 RDMA support delivers low-latency, kernel-bypass data movement for compute and storage traffic, and inline hardware-accelerated cryptographic offload lets the card handle IPsec/TLS encryption and decryption at line rate without consuming host CPU cycles — valuable for security-sensitive multi-tenant and telco workloads. As an OCP 3.0 SFF card, it installs tool-lessly into OCP-compliant server bays for streamlined, hot-swap-friendly fleet deployment. Built on the power- and cost-optimized ConnectX-6 Lx silicon, the MCX631432AE-ADAB targets cloud, edge and telco NFV deployments that need encrypted, offloaded 25GbE connectivity without the overhead of software-based encryption on the host.
