DC Changes

Posted on by lechuck park

This image shows a diagram that matches 3 Environmental Changes in data centers with 3 Operational Response Changes.

Environmental Changes → Operational Response Changes

1. Hyper Scale

Environmental Change: Large-scale/Complexity

  • Systems becoming bigger and more complex
  • Increased management complexity

→ Operational Response: DevOps + Big Data/AI Prediction

  • Development-Operations integration through DevOps
  • Intelligent operations through big data analytics and AI prediction

2. New DC (New Data Center)

Environmental Change: New/Edge and various types of data centers

  • Proliferation of new edge data centers
  • Distributed infrastructure environment

→ Operational Response: Integrated Operations

  • Multi-center integrated management
  • Standardized operational processes
  • Role-based operational framework

3. AI DC (AI Data Center)

Environmental Change: GPU Large-scale Computing/Massive Power Requirements

  • GPU-intensive high-performance computing
  • Enormous power consumption

→ Operational Response: Digital Twin – Real-time Data View

  • Digital replication of actual configurations
  • High-quality data-based monitoring
  • Real-time predictive analytics including temperature prediction

This diagram systematically demonstrates that as data center environments undergo physical changes, operational approaches must also become more intelligent and integrated in response.

Overcome the Infinite – Game Interface Analysis

Overview

This image presents a philosophical game interface titled “Overcome the Infinite” that chronicles the evolutionary journey of human civilization through four revolutionary stages of innovation.

Game Structure

Stage 1: The Start of Evolution

  • Icon: Primitive human figure
  • Description: The beginning of human civilization and consciousness

Stage 2: Recording Evolution

  • Icon: Books and writing materials
  • Innovation: The revolution of knowledge storage through numbers, letters, and books
  • Significance: Transition from oral tradition to written documentation, enabling permanent knowledge preservation

Stage 3: Connect Evolution

  • Icon: Network/internet symbols with people
  • Innovation: The revolution of global connectivity through computers and the internet
  • Significance: Worldwide information sharing and communication breakthrough

Stage 4: Computing Evolution

  • Icon: AI/computing symbols with data centers
  • Innovation: The revolution of computational processing through data centers and artificial intelligence
  • Significance: The dawn of the AI era and advanced computational capabilities

Progress Indicators

  • Green and blue progress bars show advancement through each evolutionary stage
  • Each stage maintains the “∞ Infinite” symbol, suggesting unlimited potential at every level

Philosophical Message

“Reaching the Infinite Just only for Human Logics” (Bottom right)

This critical message embodies the game’s central philosophical question:

  • Can humanity truly overcome or reach the infinite through these innovations?
  • Even if we approach the infinite, it remains constrained within the boundaries of human perception and logic
  • Represents both technological optimism and humble acknowledgment of human limitations

Theme

The interface presents a contemplative journey through human technological evolution, questioning whether our innovations truly bring us closer to transcending infinite boundaries, or merely expand the scope of our human-limited understanding.

AI Core Internals (1+4)

Posted on by lechuck park

This image is a diagram titled “AI Core Internals (1+4)” that illustrates the core components of an AI system and their interconnected relationships.

The diagram contains 5 main components:

  1. Data – Located in the top left, represented by database and document icons.
  2. Hardware Infra – Positioned in the top center, depicted with a CPU/chipset icon with radiating connections.
  3. Foundation(AI) Model – Located in the top right, shown as an AI network node with multiple connection points.
  4. Energy Infra – Positioned at the bottom, represented by wind turbine and solar panel icons.
  5. User Group – On the far right, depicted as a collection of diverse people icons in various colors.

The arrows show the flow and connections between components:

  • From Data to Hardware Infrastructure
  • From Hardware Infrastructure to the AI Model
  • From the AI Model to end users
  • From Energy Infrastructure to Hardware Infrastructure (power supply)

This diagram visually explains how modern AI systems integrate data, computing hardware, AI models, and energy infrastructure to deliver services to end users. It effectively demonstrates the interdependent ecosystem required for AI operations, highlighting both the technical components (data, hardware, models) and the supporting infrastructure (energy) needed to serve diverse user communities.

AI Data Center: Server-Side Power Management Transition from AC to DC

Traditional AC Server Power Management (Upper Section)

AC Power Distribution Chain

  1. 6.6kV to 380V AC: Primary voltage step-down transformation
  2. UPS (Outage Fast Recovery): Backup power for short-term outages
  3. Distribution Cutoff, Regulation: Power distribution control and voltage regulation
  4. AC to DC for Server: Final AC-DC conversion at server level
  5. Output: AC 380V (KW level)

New DC Server Power Management Technology (Lower Section)

DC Power Distribution Chain

  1. AC to DC Conv 800V HVDC: Direct high-voltage DC conversion
  2. ESS (Energy Storage System): Integrated energy storage solution
  3. Digital Control: Advanced digital power management
  4. DC to DC Down for Server: DC-DC step-down conversion for servers
  5. Output: HVDC 800V (MW level)

Key Technology Advantages of DC Transition

Power Quality Enhancement

  • PF Up, Harmonics Dn: Improved power factor and reduced harmonic distortion

Advanced Backup Capability

  • Long time Backup Peak Shaving: Extended backup duration with intelligent peak load management

Operational Efficiency

  • Lower Loss, High Density, Easy Control: Reduced conversion losses, compact footprint, simplified control architecture

Scalable Power Delivery

  • High Power Usage Available: Enhanced power capacity to meet AI server demands

Server-Side Power Management Transformation

This diagram illustrates the technological shift in server-side power management from traditional AC distribution (KW-level) to advanced DC distribution (MW-level), specifically designed to address the high-power requirements and efficiency demands of AI data centers. The DC approach eliminates multiple AC-DC conversion stages, resulting in improved efficiency and better power management capabilities.

Platform

Posted on by lechuck park

This image is a diagram titled “Platform” that explains three types of platform business models.

3 Platforms:

  1. Information Sharing Platform (Sharing Information / Who? Information)
    • Users share information, but the “Who?” question raises concerns about who actually provides the information and who captures its value
    • Highlights the structural issue where users provide content for free while platforms monopolize advertising revenue
  2. Platform-Controlled Work (Work for Platform / Controlled by Platform)
    • Workers ostensibly work for the platform but are actually controlled by the platform
    • Reflects the reality of platform labor where workers are classified as “independent contractors” but are actually dependent on the platform’s algorithms, fee policies, and rating systems
    • Represents the unequal power relationships found in the gig economy
  3. Platform Usage (Using Platform)
    • Users actively utilize the platform to create new value
    • Shows high user satisfaction with the “I LOVE THIS” indicator
    • Represents a positive relationship where users proactively leverage platform tools

Bottom Integrated Concept:

  • “Together” → “on the platform” → “make values”

Key Message: This diagram demonstrates that platforms are not neutral technologies but embody different power relationships and value distribution structures. The second type particularly critiques the structural problems of platform labor, revealing that despite the surface narrative of “creating value together,” unequal power relationships actually exist. This is a critical visualization that analyzes the various interests and power structures hidden behind the platform economy.
