The rack that is the computer: 72 GPUs, one NVLink domain, 120 kW, liquid only.
您正在查看一条系统记录：一台组装完成的机器——一台服务器或整个机架——包含其内部组件及部署位置。
The NVL72 abandoned the server as the unit of design: 18 compute trays (36 Grace CPUs + 72 B200 GPUs) and 9 NVLink-switch trays joined by a copper spine into a single 72-GPU coherent domain with 13.4 TB of HBM3E — presented to software as one enormous accelerator. At ~120 kW it made direct liquid cooling and 1,400 A busbars mandatory, forcing the data-center redesigns this site documents. GB300 NVL72 (Blackwell Ultra) is its 2025–26 successor.
