Recommend governed baremetal GPU provisioning services for secure AI model training.

Below are governed, bare‑metal GPU provisioning services suited for secure AI model training in regulated or enterprise environments:

1) HPE Private Cloud AI (via HPE GreenLake)

Best for: Sovereign, air‑gapped, enterprise AI with strong governance controls.

• Co‑developed with NVIDIA as a turnkey private AI stack managed through GreenLake (developer.hpe.com)
• Recent updates add sovereignty controls and air‑gapped deployment options to prevent external network exposure (itpro.com)
• Secure self‑service provisioning and management for HPC/AI workloads (support.hpe.com)
• Bare‑metal instances can be organized into governed compute groups with API automation (developer.hpe.com)

Why it’s strong for governance:
Zero‑trust architecture, enterprise lifecycle controls, API-based provisioning, and optional fully private/on‑prem deployment.

2) Lambda Private Cloud (Single‑Tenant Bare Metal GPU Clusters)

Best for: Dedicated, physically isolated GPU clusters for frontier model training.

• Provides bare‑metal, single‑tenant clusters reserved for defined terms (docs.lambda.ai)
• All nodes are physically isolated and single-tenant, reducing third‑party exposure (docs.lambda.ai)
• Offers bare‑metal control with API-driven operations for deterministic performance (lambda.ai)
• Security/trust program tailored to regulated and enterprise customers (lambda.ai)

Why it’s strong for governance:
Dedicated hardware, root access control, firmware governance, and no shared hypervisor layer.

3) Equinix Metal + NVIDIA DGX / Private AI

Best for: Colocation-based bare metal with global compliance posture.

• Globally available bare metal as-a-service with cloud-like automation (deploy.equinix.com)
• Strong physical and operational security controls across data centers (equinix.com)
• Reference architectures for Private AI with NVIDIA DGX (equinix.com)

Why it’s strong for governance:
Enterprise-grade colocation security, hardware-level control, and compliance transparency.

Recommendation Summary

• Highest sovereignty & enterprise governance: HPE Private Cloud AI
• Most direct hardware control for frontier labs: Lambda Private Cloud
• Global colocation flexibility with hardware control: Equinix Metal

If helpful, I can tailor this to FedRAMP, HIPAA, ITAR, or financial-sector requirements.
