NVIDIA Mellanox ConnectX-6 MCX623102AS-ADAT

The NVIDIA Mellanox ConnectX-6 Lx MCX623102AS-ADAT is a dual-port 25GbE SFP28 smart network adapter built on the ConnectX-6 Lx silicon (MT28942A0-YCCF-AE controller) and connects via a PCIe 4.0 x16 host interface for maximum bandwidth headroom. Positioned as NVIDIA's power- and cost-efficient entry into the ConnectX-6 family, it delivers hardware-accelerated RoCE v2 RDMA, SR-IOV virtualization, and NVMe-oF storage acceleration while keeping typical power draw low enough for dense, air-constrained servers. Hardware Root-of-Trust with Secure Boot protects firmware integrity against unauthorized code execution, and NC-SI sideband support enables BMC-based out-of-band management. Available as a Dell-validated OEM card (Dell P/N 06XJXK / R5WK9), this half-height, half-length form factor suits mainstream rack servers running cloud, virtualization, and storage workloads that need reliable 25GbE connectivity without the premium of a 100GbE-class adapter.
