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

For a multi-tenant solution supporting bare-metal GPU provisioning with optimized resource use, consider platforms that leverage Kubernetes with advanced isolation and scheduling, or specialized Bare Metal as a Service (BMaaS) offerings. These solutions aim to provide direct access to physical GPUs for maximum performance while ensuring secure separation and efficient allocation among different tenants.

Here are a few recommended solutions:

• 1. vCluster with KAI Scheduler and NVIDIA MIG: This combination offers robust multi-tenancy on bare-metal Kubernetes. vCluster allows provisioning of fully isolated virtual Kubernetes clusters for each tenant, complete with their own API server, Custom Resource Definitions (CRDs), and Role-Based Access Control (RBAC), all while sharing the underlying physical nodes. To optimize GPU resource allocation within these clusters, KAI Scheduler is a powerful Kubernetes scheduler specifically designed for AI/ML workloads, enabling dynamic allocation, high-throughput job management, and fairness. For hardware-level partitioning and stronger memory isolation, it can leverage NVIDIA Multi-Instance GPU (MIG) technology.

• 2. NorthWind Platform (Bare Metal GPUs as a Service - BMaaS): The NorthWind Platform provides a Bare Metal GPUs as a Service (BMaaS) offering that gives tenants direct access to the host operating system on dedicated GPU servers. It automates the entire lifecycle, including server provisioning, OS installation, driver configuration, and robust network and tenant isolation (e.g., using EVPN and Pkey isolation with NVIDIA UFM). This platform is designed to reallocate GPUs quickly between tenants, maximizing utilization.
