AI Infrastructure Implementation Roadmap

Executive Summary

A well-structured AI infrastructure implementation follows seven phases: assessment, design and procurement, site preparation, hardware installation, software configuration, commissioning, and operations handover. Each phase has defined milestones, go/no-go criteria, and deliverables. Projects that skip phases or proceed without meeting go/no-go criteria consistently experience delays, cost overruns, and performance problems.

Key Takeaways

Total timeline for a purpose-built AI infrastructure deployment is typically 12–24 months from project start to operational readiness.
GPU hardware procurement (Phase 2) must begin before site preparation is complete, lead times are 6–12 months.
Go/no-go criteria at each phase prevent problems from compounding, a failed go/no-go is cheaper to address early than late.
Commissioning (Phase 6) must include full-cluster testing under training load, not just individual component tests.
Operations handover (Phase 7) is as important as the technical deployment, infrastructure that works but cannot be operated is not a successful project.

Timeline note

The durations shown are for a medium-scale deployment (64–256 GPUs) in an existing facility requiring infrastructure upgrades. A new-build facility adds 6–12 months to the site preparation phase. A small deployment (8–16 GPUs) in a ready facility can be completed in 4–6 months.

Phase 01: Assessment and Requirements

Typical duration: 4–8 weeks

Milestones

→Workload assessment complete
→Site readiness assessment complete
→Compliance requirements documented
→Operational model defined

Go/No-Go Criteria

Site can support the planned deployment (or upgrade scope is defined and budgeted). Compliance requirements are documented and reviewed by legal. Executive sponsorship confirmed.

Deliverables

→Workload requirements document
→Site readiness report
→Compliance requirements matrix
→Project charter

Phase 02: Design and Procurement

Typical duration: 8–16 weeks

Milestones

→System architecture document approved
→Bill of materials finalized
→GPU hardware ordered
→Long-lead items ordered

Go/No-Go Criteria

System architecture reviewed and approved by IT, facilities, security, and compliance. Budget approved. Procurement initiated for long-lead items.

Deliverables

→System architecture document
→Bill of materials
→Purchase orders for hardware
→Procurement schedule

Phase 03: Site Preparation

Typical duration: 8–20 weeks

Milestones

→Power infrastructure upgrades complete
→Cooling infrastructure installed
→Network cabling complete
→Staging area prepared

Go/No-Go Criteria

Power infrastructure tested and certified. Cooling system commissioned and tested. Network cabling tested. Site ready for hardware installation.

Deliverables

Phase 05: Software Configuration

Typical duration: 2–4 weeks

Milestones

→Operating system deployed on all nodes
→GPU drivers and CUDA installed
→Network fabric configured (InfiniBand or RoCEv2)

→Cluster management software deployed

Go/No-Go Criteria

All nodes accessible via management network. GPU drivers installed and GPUs recognized. Network fabric operational. Storage file system mounted on all compute nodes.

Deliverables

Phase 06: Commissioning and Testing

Typical duration: 2–4 weeks

Milestones

→GPU benchmark tests passed
→Network throughput tests passed
→Storage throughput tests passed
→Full-cluster training job completed
→Acceptance criteria met

Go/No-Go Criteria

All acceptance criteria met. Full-cluster training job completed successfully. Power and cooling within design parameters under full load. Client sign-off obtained.

Deliverables

→Commissioning test report
→Acceptance test results
→As-built documentation
→Operations runbook

Phase 07: Operations Handover

Typical duration: 2–4 weeks

Milestones

→Operations team trained
→Runbooks reviewed and approved
→Monitoring and alerting configured
→Support contracts activated
→First production workload running

Go/No-Go Criteria
