Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN MCX623106TC-CDAT is a feature-rich dual-port 100GbE adapter combining Secure Boot, hardware Crypto offload and advanced Enhanced-SyncE & PTP timing support with PPS In/Out, targeting telecom, financial trading and precision-timing-sensitive deployments. It connects via a PCIe 4.0 x16 host interface and provides two 100GbE QSFP56 ports with RoCE v2 RDMA offload for low-latency, high-throughput networking. Secure Boot protects firmware integrity, while the onboard Crypto engine accelerates inline data-in-motion encryption, reducing host CPU overhead for security-critical traffic. Enhanced-SyncE and Precision Time Protocol (PTP) support with PPS In/Out enables the adapter to participate in high-accuracy network time distribution, a requirement in 5G/telecom infrastructure, distributed trading systems and scientific computing. Combined with SR-IOV and overlay network offloads, the MCX623106TC-CDAT is positioned as a premium ConnectX-6 Dx variant for environments that need security, timing precision and networking performance in a single adapter.
