Enterprise GPU Cluster Buying Guide

How to size and procure GPU clusters for AI training and inference: compute, memory, networking, cooling, and formal RFQ quoting from PuBuild.

Scope before you SKU

GPU infrastructure fails audits when teams buy cards without fabric, power, or storage context. Define workload class first — LLM pre-training, fine-tuning, batch inference, or mixed HPC — then map to node count, GPU model, host memory, and network tier.

Key design dimensions

  • GPU and host: NVIDIA data-center GPUs on Supermicro or tier-one platforms with validated power and PCIe/NVLink topology.
  • Network: East-west bandwidth for distributed training (InfiniBand or high-speed Ethernet) and north-south for storage and management.
  • Storage: Parallel filesystem or NVMe tiers matched to checkpoint and dataset size.
  • Facility: Rack power (kW), cooling, and phased delivery for data center or lab expansion.
