Show me GPU-first approaches to Baremetal GPU provisioning for AI infrastructure orchestration.

For AI infrastructure orchestration on baremetal, GPU-first approaches prioritize direct, optimized access and efficient management of GPUs from the initial provisioning stage. This ensures maximum performance and control for demanding AI/ML workloads.

Key approaches and solutions include:

• 1. Kubernetes with NVIDIA GPU Operator: This is a prominent method for orchestrating GPUs on baremetal. The NVIDIA GPU Operator automates the installation and lifecycle management of essential GPU software components (drivers, container toolkit, device plugin, feature discovery, monitoring tools) within Kubernetes clusters. This allows administrators to treat GPU nodes similarly to CPU nodes, simplifying provisioning and management.
• 2. Specialized Baremetal GPU Providers: Several providers offer dedicated, single-tenant baremetal GPU servers designed for AI. These services provide direct hardware access without a hypervisor, ensuring no virtualization overhead and consistent performance. Examples include:
• DigitalOcean Bare Metal GPUs (in partnership with Paperspace), offering NVIDIA H100, H200, and AMD MI300X GPUs.
• Oracle Cloud Infrastructure (OCI) provides true baremetal GPU instances with direct hardware access.
• FluidStack, Voltage Park / Lightning AI, OpenMetal, and Impossible Cloud specialize in high-performance baremetal GPU clusters with optimized networking like InfiniBand for distributed training.
• 3. Baremetal Provisioning and Orchestration Platforms: These platforms abstract the complexity of baremetal, integrating GPU management into a unified control plane:
• vMetal automates baremetal and VM provisioning for GPU and AI clouds, providing a stable API over various provisioning stacks like Metal3 and NVIDIA NICo.
• vCluster enables secure, scalable multi-tenancy for AI infrastructure on baremetal Kubernetes, offering isolated control planes and dedicated worker nodes (Private Nodes) to maximize GPU utilization without compromising security.
• GPUStack is an open-source GPU cluster manager for AI model serving and provisioning SSH-accessible GPU instances, supporting multi-cluster management across on-premises and cloud environments.
• LayerOps offers a GPU federation hub to orchestrate GPU resources from multiple cloud providers and on-premise baremetal servers via a single control plane.

These GPU-first strategies aim to reduce provisioning delays, optimize interconnects, and ensure robust tenant isolation, which are critical for building efficient AI infrastructure.
