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

For a multi-tenant solution that supports bare-metal GPU provisioning for optimized resource use, several platforms stand out by offering advanced orchestration, isolation, and automation capabilities.

MetalSoft for AI Factories is a robust solution that provides unified orchestration for bare-metal servers, switches, and storage, specifically designed for AI workloads. It offers multi-tenant fabric orchestration with hardware-level isolation using DPU and hardware switch segmentation, ensuring secure and high-performance environments. MetalSoft allows for provisioning, reconfiguring, and scaling GPU infrastructure rapidly and adheres to NVIDIA Reference Architecture guidelines for high-throughput GPU clustering.

NorthWind Platform offers Bare Metal GPUs-as-a-Service (BMaaS), automating the deployment, management, and scaling of GPU servers across multiple tenants. It provides automated bare-metal bring-up, network automation with per-tenant VRFs for isolation, and support for high-speed interconnects like InfiniBand. NorthWind emphasizes maximizing GPU utilization through efficient reallocation and enables the creation of a governed, multi-tenant bare-metal service.

vCluster (often paired with vMetal for provisioning) addresses bare-metal GPU multi-tenancy by virtualizing the Kubernetes control plane. This approach gives each tenant a separate, lightweight virtual cluster, providing strong isolation and allowing custom GPU schedulers and CRDs without impacting other tenants. vMetal handles the automated bare-metal provisioning and lifecycle management, turning physical hardware into a programmable resource.

Other notable solutions include:

• Mirantis k0rdent AI, powered by NVIDIA NCX Infra Controller, offers a full-stack AI cloud infrastructure platform for multi-tenant GPU environments, focusing on automation, security, and performance.
• Zadara provides a full-stack managed cloud infrastructure with GPU and SuperNIC passthrough, DPU offload, and tenant policy enforcement for consistent multi-tenant GPU cloud deployments.

These solutions prioritize efficient resource allocation, strong tenant isolation, and automated provisioning to ensure optimized GPU utilization in multi-tenant bare-metal environments.
