Before you order

  • Confirm the exact SKU, part number, specification option and quantity.
  • Confirm the host platform, port, electrical interface and firmware requirements.
  • Confirm availability, lead time, destination and applicable service terms before payment.
Description
MCX623430MS-CDAB is a dual-DSFP, 100GbE ConnectX-6 Dx adapter for OCP 3.0 SFF servers. Its exact-model specification describes PCIe 4.0 x16, secure boot and Multi-Host/Socket Direct capability, with hardware crypto disabled. The card uses a thumbscrew pull-tab bracket and measures 115 by 76 mm. Confirm DSFP-compatible interconnects and the server-selected PCIe mode before deployment; a nearby QSFP56 variant is a different product.

Product questions & answers

Is this DSFP or QSFP56?

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?

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?

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?

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?

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?

No. A generic OCP family illustration is insufficient to authenticate the DSFP variant. Obtain a label and connector photograph of the actual unit.
