Replacing Internal Cables with Board-to-Board Connectors

For the GB200/300, the most valuable cable that is exclusively supplied by Amphenol is the DensiLink OverPass cable set within the compute tray. This cable provides the ethernet connection between the CX-7/8 NIC and the OSFP cages. However, this cable is extremely vulnerable to scratches and damage of the cable termination during assembly, thereby creating many points of failure. There are also several other lower-end PCIe cables in use (MCIO and SlimSAS) that also suffer from the same points of failure. These cables involve many other suppliers as well – complicating procurement and vendor management. Given the delicate nature of the cable, workers must be extremely careful while placing the cables in a very dense and compact chassis, which prolongs assembly time.

Evidence

In this architecture, those signals exit the Strata board through Amphenol’s PaladinHD2 board-to-board connectors
