The article talks about NVidia racks, but also about their DSF [0], which is Ethernet-based (as opposed to Infiniband) built on switches using Cisco and Broadcom chipsets and custom ASIC xPU accelerators such as their own MTIA [1] which is built for them by Broadcom. So they are talking more than one approach simultaneously.
