ConnectX-6 Dx Card technical selection Q&A
Owner-confirmed and documentation-backed questions with explicit variant applicability and source boundaries.
These questions were prepared for technical evaluation from cited documentation. They are not a measured list of frequently asked customer questions. The applicability line belongs to each answer; do not transfer a statement between order-code, firmware, cooling, length, form-factor or crypto variants.
The products listed below are the applicable catalog references. Answers use owner-confirmed manufacturer-origin product data, scoped public documentation, or explicitly stated engineering guidance. Genuine conflicting values are qualified individually.
Is this DSFP or QSFP56?
Applicable catalog candidates: 900-9X675-0076-MB0.
The exact-model specifications and ordering table specify dual DSFP. The general introduction overview conflicts; confirm the exact label and connector before purchase.

Are crypto and secure boot enabled?
Applicable catalog candidates: 900-9X675-0076-MB0.
The exact-model section says crypto disabled and secure boot enabled. Do not infer crypto from another ConnectX-6 Dx OCP variant.

Which form factor and bracket are required?
Applicable catalog candidates: 900-9X675-0076-MB0.
OCP 3.0 SFF, 115 x 76 mm, with thumbscrew pull-tab retention. It is not a conventional PCIe stand-up card.

Is Multi-Host automatically available?
Applicable catalog candidates: 900-9X675-0076-MB0.
The SKU is specified as Multi-Host/Socket Direct capable, but the OCP baseboard and PCIe bifurcation determine the active host configuration.

What does the power figure mean?
Applicable catalog candidates: 900-9X675-0076-MB0.
With passive cables, NVIDIA lists 19 W typical active power under ATIS traffic load and 26.6 W maximum active power. Optics, standby mode and airflow must be assessed separately.

Can the family picture prove the delivered connector?
Applicable catalog candidates: 900-9X675-0076-MB0.
No. A generic OCP family illustration is insufficient to authenticate the DSFP variant. Obtain a label and connector photograph of the actual unit.
