Product Description
The NVIDIA Mellanox ConnectX-6 Dx MCX623105AC-CDAT is a single-port 100GbE smart network adapter built on the ConnectX-6 Dx controller and a PCIe 4.0 x16 host interface. It targets security-conscious cloud and enterprise deployments, pairing hardware-accelerated RoCE v2 RDMA with an onboard cryptography engine for inline IPsec/TLS offload and Secure Boot for firmware integrity protection. ASAP² technology offloads Open vSwitch and SR-IOV virtual switching to the NIC, freeing host CPU cycles for application workloads, while advanced congestion control and QoS keep latency predictable under mixed traffic. The QSFP56 port supports 100GbE connectivity for storage, compute, and AI fabric interconnects. Combining strong throughput, hardware-rooted security, and full virtualization offload in a single-port form factor, the MCX623105AC-CDAT suits software-defined data centers, secure multi-tenant clouds, and NVMe-oF storage targets that require verified boot and encrypted data-in-motion without compromising performance.
