Question

A data center operations team is planning to deploy several NVIDIA HGX H100 8-GPU systems in an existing on-premises facility. Each server draws roughly 10 kW at full load. The facility's current racks are provisioned for 7 kW per rack with traditional room-based air cooling. Before purchasing the systems, what infrastructure consideration should the team address first to ensure a viable deployment?

Accepted Answer

Evaluate the facility's power delivery and cooling capacity, since high-density GPU systems may exceed existing per-rack power and heat-removal limits and could require higher-capacity circuits and liquid or rear-door cooling

Answer

Order additional NVLink switches so the GPUs can communicate across racks at full bandwidth

Answer

Increase the object-storage capacity to hold model checkpoints before power is considered

Answer

Standardize all nodes on the same CUDA toolkit version to avoid container portability issues
