NVIDIA Mellanox ConnectX-6 MCX621202AS-ADAT

The NVIDIA Mellanox ConnectX-6 Dx MCX621202AS-ADAT is a dual-port 25GbE SFP28 network adapter from NVIDIA's ConnectX-6 Dx EN family, connecting via a PCIe 4.0 x8 host interface. ConnectX-6 Dx builds on the ConnectX-6 architecture with an advanced hardware-based ASAP2 (Accelerated Switch and Packet Processing) offload engine for software-defined networking, alongside hardware-accelerated RoCE v2 RDMA and NVMe-oF storage acceleration. This SKU includes hardware Root-of-Trust with Secure Boot to guard firmware integrity, SR-IOV for virtualized multi-tenant networking, and NC-SI sideband management for BMC-based monitoring. Purpose-built for cloud and enterprise data centers that need line-rate 25GbE connectivity with rich hardware offloads and low CPU overhead, it targets virtualization, network-function, and storage-networking workloads where secure, high-throughput Ethernet connectivity and reduced host CPU utilization are priorities. Backed by NVIDIA's broad OS and hypervisor driver ecosystem.
