Product questions & answers
Is its Ethernet mode the same as its 800 Gb/s InfiniBand mode?
No. The order table lists 800 Gb/s XDR InfiniBand as the default and 2 x 400 GbE Ethernet. Validate the specific port configuration and interconnect.
What extension type does this exact suffix provide?
This suffix specifies an x16 Socket Direct extension option. The auxiliary kit is separate and needs a compatible server topology.
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 Gen 6/Gen 5/rate wording. Confirm the complete auxiliary assembly before promising its generation or throughput.
