ConnectX-6 Dx technical selection questions

These questions are prepared from the cited technical documentation and clearly scoped owner inputs. They are not a measured frequency ranking. Keep the applicability line with each answer; do not transfer board, cooling, crypto, protocol, cable length or firmware facts between variants.

Does the AN variant include secure boot or hardware crypto?

Applicable canonical content subjects: 900-9X6AG-0056-ST1.

No. The exact model-specific section explicitly disables both. AS enables secure boot without crypto; AC and AE have other security combinations.

Is it the single-port 100 GbE card?

Applicable canonical content subjects: 900-9X6AG-0056-ST1.

No. MCX623106AN-CDAT has two QSFP56 ports. MCX623105 variants are a separate single-port design.

How should the power figures be interpreted?

Applicable canonical content subjects: 900-9X6AG-0056-ST1.

The exact table gives 19.52 W typical and 26.64 W maximum at PCIe Gen 4 with passive cables. Active-module consumption is additional under the documented formula; these are not universal host-system power figures.

What cooling condition is documented?

Applicable canonical content subjects: 900-9X6AG-0056-ST1.

At55°C the table specifies 550 LFM from heatsink to port with passive cables and 700 LFM for its listed 2.5 W active-module condition. Confirm the actual optic thermal design and server airflow.

Does QSFP56 establish 200 GbE support for this code?

Applicable canonical content subjects: 900-9X6AG-0056-ST1.

No. This exact dual-port 106 CDAT model lists Ethernet rates up to 100 Gb/s. Connector family alone does not establish an enabled rate.

Can a 5G video-pipeline case prove this exact SKU’s performance?

Applicable canonical content subjects: 900-9X6AG-0056-ST1.

No. The cited Mavenir/NVIDIA integration is a ConnectX-6 Dx family validation with its own software and workload. It informs offload evaluation but does not identify this exact ordering code or guarantee its application throughput.
