Product Description
The NVIDIA Mellanox ConnectX-6 Lx MCX631435AE-GDAB is an OCP 3.0 Small Form Factor network adapter that adds hardware-accelerated inline cryptography to RDMA-class 50GbE networking for Open Compute Project-compliant server platforms. Built on the ConnectX-6 Lx ASIC (MT28942A0-YCCF-AE) and connected via PCIe 4.0 x8, the card delivers one 50Gb/s QSFP28 port with RDMA over Converged Ethernet (RoCE v2). The Crypto-enabled variant offloads IPsec and TLS encryption to hardware, protecting network traffic without consuming host CPU cycles — valuable for multi-tenant cloud and regulated workloads deployed on OCP NIC infrastructure. Combined with ASAP² virtual switching offload and SR-IOV, and the tool-less serviceability of the OCP 3.0 form factor, the MCX631435AE-GDAB fits hyperscale and enterprise fleets that need encrypted networking without the added cost of Secure Boot.
