NVIDIA DGX GB Rack Scale Systems User Guide#

The NVIDIA DGX GB Rack Scale Systems User Guide is also available as a PDF.

This document contains detailed information about the hardware and software stack of DGX Grace Blackwell rack scale systems (such as GB200 and GB300). Each rack is an NVL72 rack (72-GPU NVL domain). The guide applies to single NVL72 racks and to multi-rack deployments such as a SuperPOD (eight NVL72 racks). In the context of this guide, the system is defined as a rack scale solution for GPUs connected by NVIDIA NVLink®.

This rack scale architecture enables the following:

  • Support for higher GPU and module power.

  • Improved serviceability with modular building blocks.

  • Support for a large L1 NVLink domain size.

  • Scalable and non-scalable solutions in a common infrastructure.
