Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN MCX623106AC-CDAT is a dual-port 100GbE network adapter that combines hardware Secure Boot and inline Crypto data encryption offload on the ConnectX-6 Dx platform, aimed at security-conscious enterprise and service-provider deployments. It connects via a PCIe 4.0 x16 host interface and delivers two 100GbE QSFP56 ports with RoCE v2 RDMA offload for high-throughput, low-latency networking. Secure Boot ensures only cryptographically signed firmware can execute on the device, while the Crypto engine accelerates data-in-motion encryption (such as IPsec/TLS), offloading that work from the host CPU. The card is form-factor and functionally aligned with HPE's equivalent SKU (part numbers SN37A28327, 4XC7A08248 and 01PE649), making it a suitable option for OEM-based server refresh and expansion projects. Rounded out with SR-IOV and overlay network offloads, the MCX623106AC-CDAT delivers a strong balance of performance, security and OEM compatibility for modern data center deployments.
