GPU Racks: The Heart of the Colossus

The GPU racks are the heart of the Colossus, with each rack containing 64 GPUs and 16 CPUs. The GPUs are cooled using liquid cooling, while the CPUs are cooled using air cooling. The racks are designed to be highly scalable, with each rack capable of supporting up to 512 GPUs. This allows for easy expansion and upgrade of the facility, making it an ideal solution for large-scale AI applications.
