Product Description
The NVIDIA Mellanox ConnectX-6 Dx MCX623106PC-CDAT is a dual-port 100GbE network adapter built on the ConnectX-6 Dx controller with a PCIe 4.0 x16 host interface. It combines Secure Boot firmware attestation and inline IPsec/TLS crypto offload with PPS (Pulse-Per-Second) In/Out support, making it well suited to precision-timing use cases layered on top of secure, high-throughput networking. Dual QSFP56 100GbE ports provide link redundancy or aggregate bandwidth for demanding fabrics, while RoCE v2 RDMA and ASAP² hardware offload deliver low-latency data movement and CPU-efficient virtual switching. The PPS interface allows the card to synchronize with, or distribute, an external precision time reference — useful for telecom, financial trading, and distributed measurement systems that must correlate events across nodes with tight timing tolerances. Together, security, throughput, and timing precision make this SKU a strong fit for regulated, latency-sensitive, and time-synchronized infrastructure.
