Nvidia has announced a series of ConnectX-7 network adapters in a variety of form factors and as a single chip, including pcie fhhl and hhl, ocp 3.0 sff. One, two, or four ports are provided, and the card requires 16 or 32 PCIe 5.0 lanes to provide full bandwidth. Supported interfaces are sfp56, qsfp56, qsfp56-dd, sfp12, and qsfp112.
There is a heavy heatsink screwed into the uniquely shaped backplate to dissipate the heat from the optical transmitters. Model shown is the NDR200 MCX75210AAS-HEAT with 200 gigabit Ethernet ports and full PCIe slot support.
Four of these controllers can be coupled together, as with the Cedar Fever 1.6Tbps modules, two of which are in the DGX H100.
In addition to these network cards, the A100 accelerator was also shown as the sxm version with a heatsink at the ISC 2022 fair held in Hamburg so far.
