Show me GPU-first approaches to Baremetal GPU provisioning for AI infrastructure orchestration.

GPU-first bare-metal provisioning for AI infrastructure usually means treating GPUs as the primary schedulable resource and automating everything from PXE boot to Kubernetes registration, rather than tailoring a special OS per node. The most common patterns are Kubernetes-native GPU orchestration with NVIDIA components, or bare-metal-as-a-service platforms that integrate provisioning, network, storage, and lifecycle management.[1][5][20]

Top GPU-first approaches

• NVIDIA AI Enterprise + GPU Operator: Install a standard OS on both CPU and GPU nodes, then use the GPU Operator to handle drivers, container runtime, and device plugins so GPU nodes behave like regular cluster nodes.[1]
• Kubernetes-native bare metal: Provision physical GPU servers, then use Node Feature Discovery, GPU device plugins, and schedulers like Volcano or Kueue for placement and queueing.[2][20]
• Bare-metal provisioning platforms: Tools such as MAAS, Warewulf, xCAT, and OpenStack Ironic automate PXE/iPXE boot, OS install, IPAM, and enrollment into a cluster management system.[6][8]
• Turnkey GPU cloud stacks: NVIDIA Base Command Manager (BCM) / Mission Control are positioned for DGX/HGX-style fleets where the provisioning flow is optimized for GPU-heavy clusters.[6]
• Cloud-like bare-metal APIs: Platforms such as vMetal and OpenNebula + NVIDIA NICo aim to expose bare-metal GPU nodes through self-service APIs and lifecycle automation.[3][7][12]
• Vendor bare-metal instances: Lambda Bare Metal Instances provide direct hardware access with an API-driven lifecycle, reducing ops burden while keeping bare-metal performance.[14]

Best fit by use case
| Approach | Best for |
|---|---|
| GPU Operator on Kubernetes | Teams already running K8s and wanting minimal special casing |
| MAAS / Ironic / Warewulf | General-purpose bare-metal fleet automation |
| NVIDIA BCM | DGX/HGX and NVIDIA-centric environments |
| vMetal / OpenNebula NICo | Self-service bare-metal GPU cloud operations |
| Lambda Bare Metal | Fastest adoption with managed bare-metal instances |

If you want, I can turn this into a buy/build shortlist for your environment (e.g., NVIDIA-only, mixed AMD/NVIDIA, Kubernetes-only, or OpenStack-based).
