Product Description
The NVIDIA Mellanox ConnectX-6 Dx MCX623105AE-CDAT is a single-port 100GbE network adapter built on the ConnectX-6 Dx controller with a PCIe 4.0 x16 host interface. It shares the same high-throughput RDMA and virtualization offload architecture as its Secure Boot sibling but omits the Secure Boot feature, making it a cost-optimized option for environments where firmware attestation is not a requirement but hardware-accelerated inline cryptography is. The onboard crypto engine offloads IPsec and TLS encryption/decryption, reducing host CPU load for data-in-motion protection. RoCE v2 RDMA delivers low-latency, high-throughput remote data access, while ASAP² hardware offload accelerates Open vSwitch and SR-IOV-based virtual networking. With a single QSFP56 100GbE port, the MCX623105AE-CDAT fits general-purpose compute nodes, storage servers, and cloud infrastructure that need encrypted networking and virtualization performance without the added cost of hardware Secure Boot.
