The diagram illustrates a tiered approach to Numeric Data Processing, moving from simple monitoring to advanced predictive analytics:
1-D Processing (Real-time Detection): This layer focuses on individual metrics. It emphasizes high-resolution data acquisition with precise time-stamping to ensure data quality. It uses immediate threshold detection to recognize critical changes as they happen.
Static Processing (Statistical & ML Analysis): This stage introduces historical context. It applies statistical functions (like averages and deviations) to identify trends and uses Machine Learning (ML) models to detect anomalies that simple thresholds might miss.
n-D Processing (Correlative Intelligence): This is the most sophisticated layer. It groups multiple metrics to find correlations, creating “New Numeric Data” (synthetic metrics). By analyzing the relationship between different data points, it can identify complex root causes in highly interleaved systems.
Summary
The framework transitions from reactive 1-D monitoring to proactive n-D correlation, enhancing the depth of system observability.
It integrates statistical functions and machine learning to filter noise and identify true anomalies based on historical patterns rather than just fixed limits.
The ultimate goal is to achieve high-fidelity data processing that enables automated severity detection and complex pattern recognition across multi-dimensional datasets.

💡 Summary & Key Takeaways
The slide suggests that traditional operating methods are unsustainable due to the costs and risks associated with AI workloads.
Success in the AI era requires precisely integrating IT and facility data (Digitization), utilizing advanced technologies like Digital Twins and AI Agents (Solutions), and adopting fast, integrated processes (Operations).

Why Modular DC is Critical for AI Data Centers
Speed & Agility
Traditional data centers take 18-24 months to build, but AI demands are exploding NOW. Modular DCs deploy in 3-6 months, allowing organizations to capture market opportunities and respond to rapidly evolving AI compute requirements without lengthy construction cycles.
AI-Specific Thermal Challenges
AI workloads generate 3-5x more heat per rack (30-100kW) compared to traditional servers (5-10kW). Modular designs integrate advanced liquid cooling and containment systems from day one, purpose-built to handle GPU/NPU thermal density that would overwhelm conventional infrastructure.
Elastic Scalability
AI projects often start experimental but can scale exponentially. The “pay-as-you-grow” model lets organizations deploy one block initially, then add capacity incrementally as models grow—avoiding massive upfront capital while maintaining consistent architecture and avoiding stranded capacity.
Edge AI Deployment
AI inference increasingly happens at the edge for latency-sensitive applications (autonomous vehicles, smart manufacturing). Modular DCs’ compact, self-contained design enables AI deployment anywhere—from remote locations to urban centers—with full data center capabilities in a standardized package.
Operational Efficiency
AI workloads demand maximum PUE efficiency to manage operational costs. Modular DCs achieve PUE of 1.1-1.3 through integrated cooling optimization, HVDC power distribution, and AI-driven management—versus 1.5-2.0 in traditional facilities—critical when GPU clusters consume megawatts.
Key Advantages
📦 “All pack to one Block” – Complete infrastructure in pre-integrated modules 🧩 “Scale out with more blocks” – Linear, predictable expansion without redesign
⏱️ Time-to-Market: 4-6x faster deployment vs traditional builds
💰 Pay-as-you-Grow: CapEx aligned with revenue/demand curves
🌍 Anywhere & Edge: Containerized deployment for any location
Summary
Modular Data Centers are essential for AI infrastructure because they deliver pre-integrated, high-density compute, power, and cooling blocks that deploy 4-6x faster than traditional builds, enabling organizations to rapidly scale GPU clusters from prototype to production while maintaining optimal PUE efficiency and avoiding massive upfront capital investment in uncertain AI workload trajectories.
The modular approach specifically addresses AI’s unique challenges: extreme thermal density (30-100kW/rack), explosive demand growth, edge deployment requirements, and the need for liquid cooling integration—all packaged in standardized blocks that can be deployed anywhere in months rather than years.
This architecture transforms data center infrastructure from a multi-year construction project into an agile, scalable platform that matches the speed of AI innovation, allowing organizations to compete in the AI economy without betting the company on fixed infrastructure that may be obsolete before completion.
