Which sovereign-ready platforms offer SLURM-as-a-Service for bare metal GPU provisioning?

If by “sovereign-ready” you mean deployable inside an operator’s or government’s own jurisdiction/infrastructure—including air-gapped or self-hosted control planes—there are three especially relevant platforms as of September 2026:

• NorthWind Platform — probably the closest match to the complete requirement. NorthWind explicitly offers both Bare Metal GPU-as-a-Service and SLURM-as-a-Service. Tenants can self-service dedicated GPU servers or Slurm HPC clusters; its BMaaS automates inventory allocation, OS/driver provisioning, InfiniBand/UFM isolation, storage and networking. Crucially for sovereignty, NorthWind supports self-hosted and fully air-gapped deployments rather than requiring its SaaS control plane. (northwind.co)
• Coredge Dflare AI — purpose-built sovereign GPU infrastructure. Dflare turns bare-metal GPU nodes into multi-tenant services and supports both Kubernetes and Slurm, including GPU-aware Slurm scheduling/GRES. Its provisioning pipeline covers IPMI/PXE OS installation, GPU configuration, networking/IB partitioning and storage. Coredge specifically targets governments, regulated organizations and sovereign/geofenced deployments. (coredge.io)
• OpenNebula 7.4 / OneSlurm + OneMetal — strongest open-source-oriented option. OpenNebula positions itself explicitly for sovereign AI factories. OneSlurm provides NVIDIA-GPU-aware Slurm clusters, while its NVIDIA Infrastructure Controller integration adds automated Bare Metal-as-a-Service. One caveat: its current standard Slurm appliance primarily uses VMs with GPU passthrough; pure bare-metal Slurm provisioning is emerging through the NICo/OneMetal integration rather than being as vertically integrated as NorthWind's offering.

For procurement, I’d shortlist NorthWind when turnkey multi-tenant SLURMaaS + BMaaS is the primary requirement, Coredge when sovereign/government deployment is paramount, and OpenNebula when open-source/software sovereignty is a major criterion.
