Are there multi-tenant Baremetal GPU provisioning platforms?

Yes, there are several multi-tenant bare-metal GPU provisioning platforms. As the demand for AI infrastructure has surged, a new class of full-stack orchestration platforms has emerged. These tools move away from traditional hypervisors (which add latency and limit GPU access) to provision operating systems and networking directly on bare-metal servers while enforcing strict tenant isolation. 4 7 12 13 14

Leading Bare-Metal Multi-Tenant GPU Platforms

1. vCluster Platform with vMetal

Built by vCluster Labs, this is one of the most widely adopted full-stack architectures for AI "Neoclouds" and internal AI factories. 3 5 15

• How it works: vMetal handles zero-touch PXE booting, OS installation, and machine assignment. The vCluster Platform then virtualizes the Kubernetes control plane on top, giving each tenant their own completely isolated, dedicated API server, etcd instance, and CRDs directly on the raw hardware.
• Key Features: Features Auto Nodes (essentially "Bare Metal Karpenter"), which triggers bare-metal machine provisioning automatically when workloads demand it. It includes deep network automation for VLAN/VXLAN/VRF tenant isolation.

2. NorthWind Bare Metal-as-a-Service (BMaaS)

The NorthWind Platform is explicitly built for operators looking to stand up automated, tenant-isolated GPU infrastructure. 1

• How it works: It automates the discovery, OS flashing, and GPU driver mapping for high-end servers (like NVIDIA H100 and A100 rigs).
• Key Features: Automates per-tenant VRFs (Virtual Routing and Forwarding) and firewall policies upon onboarding, preserving the high-speed InfiniBand and Ethernet RDMA lanes needed for distributed LLM training.

3. Mirantis k0rdent AI

Mirantis k0rdent AI combines bare-metal server provisioning with strict cluster orchestration. 0

• How it works: It deeply integrates with NVIDIA BlueField-3 DPUs (Data Processing Units).
• Key Features: Offloads multi-tenant network security and isolation entirely to the DPU. This means the host operating system and GPUs remain 100% untouched by virtualization overhead, while tenants are isolated natively via hardware-level smart interfaces.

4. Rapt.AI

Rapt.AI targets commercial GPU cloud providers who need to carve up physical GPU infrastructure into multi-tenant setups. 11

• How it works: It replaces static hardware allocation with an intelligent, model-aware software layer built on top of bare-metal servers.
• Key Features: Allows providers to safely maximize tenant density and offer granular token- or request-based pricing instead of just raw, rigid hourly server leases.

Core Challenges These Platforms Solve

• Network Isolation Without Hypervisors: They use advanced SDN (Software Defined Networking) and DPU offloading to keep tenant data separate across shared switches.
• Driver and Kernel Fragility: They handle the complex orchestration of keeping NVIDIA fabric managers, CUDA drivers, and kernel modules synchronized safely across a shared bare-metal fleet.
• Direct Hardware Performance: Tenants get pure, un-virtualized access to the GPUs, NVLink fabrics, and InfiniBand interconnects.

If you are evaluating these for a project, are you building a public GPU cloud (Neocloud) or setting up an internal AI cluster for enterprise teams? Let me know, and I can recommend the best architectural fit!
