Product Description
The NVIDIA Mellanox ConnectX-6 Dx MCX621102AE-ADAT is a dual-port 25GbE SFP28 adapter from the ConnectX-6 Dx EN family, connecting via a PCIe 4.0 x8 host interface. It pairs ConnectX-6 Dx's ASAP2 hardware offload engine and hardware-accelerated RoCE v2 RDMA with inline crypto acceleration, letting data-in-motion encryption run at line rate without consuming host CPU cycles, while omitting the Secure Boot firmware-attestation feature found on other ConnectX-6 Dx SKUs. SR-IOV virtualization and NC-SI sideband management support secure, multi-tenant deployments with BMC-based out-of-band monitoring, and hardware storage acceleration extends the card's usefulness to NVMe-oF storage networking. Stateless CPU offloads, jumbo frame support, and hardware QoS complete a feature set aimed at cloud, enterprise, and telco environments that need hardware-encrypted 25GbE connectivity and rich SDN offload without the added cost of firmware Secure Boot attestation.
