The 18 compute trays and the 9 NVLink switch trays come together to form this GB200NVL72 system, which is just one rack in an AI data center. This one rack has 1.4 exaflops of AI training performance in it. Just to be clear, there are only a few exaflops supercomputers on Earth today, and Nvidia just built one in a single 120kW rack that they sell off the shelf.
