NVIDIA Mellanox ConnectX-6 MCX631105AE-GDAT

The NVIDIA Mellanox ConnectX-6 Lx MCX631105AE-GDAT is a single-port 50GbE PCIe HHHL network adapter that pairs efficient RDMA networking with hardware-accelerated inline cryptography. 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) for low-latency, CPU-efficient data transfer. The Crypto-enabled variant adds inline IPsec and TLS offload, encrypting and decrypting network traffic in hardware without consuming host CPU cycles — a capability important for multi-tenant cloud, financial services, and government workloads that require data-in-motion encryption. Combined with ASAP² virtual switching offload and SR-IOV support, the MCX631105AE-GDAT gives IT teams a compact, power-efficient adapter that meets both performance and compliance requirements for encrypted east-west and north-south traffic in modern data centers.
