Product Description
The NVIDIA Mellanox ConnectX-6 Lx MCX623102AN-ADAT is a dual-port 25GbE SFP28 network adapter built on the ConnectX-6 Lx silicon (MT28942A0-YCCF-AE controller), connecting via a PCIe 4.0 x16 host interface that provides bandwidth headroom beyond the card's dual 25GbE ports. As part of NVIDIA's power- and cost-efficient ConnectX-6 line, it delivers hardware-accelerated RoCE v2 RDMA, SR-IOV virtualization, and NVMe-oF storage acceleration in a compact half-height, half-length form factor. Stateless CPU offloads, jumbo frame support, and hardware QoS reduce host CPU utilization while sustaining line-rate 25GbE throughput, and NC-SI sideband support enables BMC-based out-of-band management. This baseline SKU omits Secure Boot and inline crypto acceleration, making it a cost-optimized choice for platforms already standardized on PCIe x16 slots that need reliable, general-purpose 25GbE Ethernet connectivity for cloud, virtualization, and storage-networking workloads.
