NVIDIA Mellanox ConnectX-6 MCX623102AN-GDAT

The NVIDIA Mellanox ConnectX-6 Dx EN MCX623102AN-GDAT is a dual-port 50GbE standard-form-factor PCIe adapter card built for high-throughput Ethernet connectivity without the added Secure Boot or crypto-offload firmware options carried by other MCX623102 SKUs. It uses a PCIe 4.0 x16 host interface and dual SFP56 cages to deliver line-rate 50 Gigabit Ethernet per port, with RoCE v2 RDMA offload providing low-latency, kernel-bypass data movement for compute and storage traffic. As the baseline SKU in this sub-family, the MCX623102AN-GDAT is a straightforward choice for data center operators who need ConnectX-6 Dx's core networking performance — high bandwidth, RDMA offload, and ASAP² hardware-accelerated virtual switching — without requiring the additional hardware security feature set of the Secure-Boot or crypto-enabled variants. It installs in conventional server PCIe slots and is well suited to general-purpose high-bandwidth Ethernet networking, AI/ML data pipelines, and storage connectivity where those extra security offloads are not a purchasing requirement.
