Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN adapter (MCX623105AN-VDAT) is the baseline single-port 200GbE SKU in the ConnectX-6 Dx family, pairing a PCIe 4.0 x16 host interface with a QSFP56 port capable of line-rate 200Gb Ethernet. Built on the same cloud-optimized ConnectX-6 Dx ASIC as the security-hardened variants, it delivers hardware-accelerated RDMA over Converged Ethernet (RoCE v2), ASAP^2 offloads for virtual switch and packet processing (OVS/OVS-DPDK), and SR-IOV-based virtual function support for VM and container I/O, without the added cost of Secure Boot or inline Crypto offload. This makes the MCX623105AN-VDAT a cost-effective choice for organizations that need ConnectX-6 Dx's throughput, offload, and virtualization features but do not require hardware-enforced firmware attestation or inline IPsec/TLS encryption. It is a strong fit for general-purpose 200GbE server connectivity in AI, HPC, and data center environments where encryption is handled elsewhere in the stack.
