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
The ConnectX-8 C8180 is an HHHL SuperNIC with a single OSFP cage and a PCIe 6 x16 host interface. The documented default InfiniBand configuration is 800Gb/s XDR; Ethernet is listed as 2 x 400GbE. This exact variant provides an x16 downstream-port extension option, with crypto and secure boot enabled. Use compatible RHS OSFP interconnects and verify the end-to-end port configuration before deployment.

Product questions & answers

Is its Ethernet mode the same as its 800Gb/s InfiniBand mode?

No. The order table lists 800Gb/s XDR InfiniBand as the default and 2 x 400GbE Ethernet. Validate the specific port configuration and interconnect.

What extension type does this exact suffix provide?

DT0 specifies a downstream-port extension. It is distinct from the ST0 Socket Direct option.

Which OSFP cooling style is supported?

The exact specification section requires an RHS, or Riding Heatsink, OSFP cage arrangement. Match the interconnect mechanical and thermal design.

Can the partner-cooled card be deployed without a cooling design?

This is the standard C8180 configuration. The SL0 partner-cooled version is a distinct variant; server cooling still needs validation.

How is PPS exposed?

NVIDIA lists PPS input/output access through the optional 930-9XCBL-000A-000 cable-extender debugging kit.

Are all auxiliary-link generation claims consistent?

No. The main card is PCIe 6 x16, but auxiliary-kit ordering, contents and technical tables use inconsistent Gen6/Gen5/rate wording. Confirm the complete auxiliary assembly before promising its generation or throughput.
