Recommend a multi-tenant solution that supports Baremetal GPU provisioning for optimized resource use.

For optimized resource utilization in a multi-tenant environment requiring bare-metal GPU provisioning, several robust solutions integrate bare-metal management with multi-tenancy and orchestration.

Here are some recommended solutions:

• 1. OpenNebula with NVIDIA NCX Infra Controller: This integrated solution provides end-to-end automation. NVIDIA NCX Infra Controller handles bare-metal lifecycle management for GPU servers, including hardware discovery, OS deployment, and node configuration. OpenNebula then operates at the cloud control layer, offering multi-tenant orchestration, governance, and quota management, allowing tenants to consume GPU resources via IaaS or deploy Kubernetes clusters for AI workloads.

• 2. MetalSoft: MetalSoft offers unified orchestration for the entire bare-metal stack, including servers, switches, and storage. It focuses on direct infrastructure access to maximize AI performance and provides multi-tenant fabric orchestration with hardware-level isolation using DPUs and switch segmentation, ensuring secure and efficient resource sharing.

• 3. vMetal (from vCluster Labs) and vCluster: vMetal automates bare-metal provisioning, network orchestration, and the lifecycle management of GPU nodes. When combined with vCluster, it creates a unified, programmable platform for AI infrastructure, enabling "hard multi-tenancy" across networking, nodes, and Kubernetes clusters. vCluster specifically provisions fully isolated tenant Kubernetes clusters on shared GPU infrastructure, each with its own API server and control plane.

These solutions leverage technologies like NVIDIA Multi-Instance GPU (MIG) for sharing within a node and NVIDIA Quantum InfiniBand for multi-tenant fabric security and isolation, ensuring both performance and secure tenant separation.
