Posted on 2026-03-112026-03-10 by lechuck park

1. Core Components (Left Panel)

The left side outlines the fundamental building blocks of a DPU, detailing how tasks are distributed across its hardware:

Control Plane (Multi-core ARM CPU): Operates independently from the host server, running a localized OS and infrastructure management services.
Data Path (Hardware Accelerators with FPGA): Utilizes specialized silicon to handle heavy, repetitive tasks like packet processing, cryptography, and data compression at wire-speed without latency.
I/O Ports (Network Interfaces): Correction Note: The description text in your image here is accidentally duplicated from the “Data Path” section. Ideally, this should note the physical connections, such as high-bandwidth Ethernet or InfiniBand (100G/400G+), designed to ingest massive data center traffic.
PCIe Gen 4/5/6 (Host Interface): Provides the high-bandwidth, low-latency bridge connecting the DPU to the host’s CPU and GPUs.

2. Key Use Cases (Right Panel)

The right side highlights how these hardware components translate into tangible infrastructure benefits:

Network Offloading: Shifts complex network protocols (OVS, VxLAN, RoCE) away from the host CPU, reserving those critical compute cycles entirely for AI workloads.
Storage Acceleration: Leverages NVMe-oF to disaggregate storage, allowing the server to access remote storage arrays with the same low latency and high throughput as local drives.
Security Offloading: Enforces Zero Trust and micro-segmentation directly at the server edge by performing inline IPsec/TLS encryption and firewalling.
Bare-Metal Isolation: Creates an “air-gapped” environment that physically separates tenant applications from infrastructure management, eliminating the need for management agents on the host OS.

Summary

This infographic perfectly illustrates how DPUs transform server architectures by offloading critical network, storage, and security tasks to specialized hardware. By isolating infrastructure management from core compute resources, DPUs maximize overall efficiency, making them an indispensable foundation for a high-performance AI Data Center Integrated Operations Platform.

New Era of Digitals

Posted on 2025-09-232025-09-19 by lechuck park

This image presents a diagram titled “New Era of Digitals” that illustrates the evolution of computing paradigms.

Overall Structure:

The diagram shows a progression from left to right, transitioning from being “limited by Humans” to achieving “Everything by Digitals.”

Key Stages:

Human Desire: The process begins with humans’ fundamental need to “wanna know it clearly,” representing our desire for understanding and knowledge.
Rule-Based Era (1000s):
- Deterministic approach
- Using Logics and Rules
- Automation with Specific Rules
- Record with a human recognizable format
Data-Driven Era:
- Probabilistic approach (Not 100% But OK)
- Massive Computing (Energy Resource)
- Neural network-like structures represented by interconnected nodes

Core Message:

The diagram illustrates how computing has evolved from early systems that relied on human-defined explicit rules and logic to modern data-driven, probabilistic approaches. This represents the shift toward AI and machine learning, where we achieve “Not 100% But OK” results through massive computational resources rather than perfect deterministic rules.

The transition shows how we’ve moved from systems that required everything to be “human recognizable” to systems that can process and understand patterns beyond direct human comprehension, marking the current digital revolution where algorithms and data-driven approaches can handle complexity that exceeds traditional rule-based systems.

Multi-DCs Operation with a LLM(3)

Posted on 2025-09-12 by lechuck park

This diagram presents the 3 Core Expansion Strategies for Event Message-based LLM Data Center Operations System.

System Architecture Overview

Basic Structure:

Collects event messages from various event protocols (Log, Syslog, Trap, etc.)
3-stage processing pipeline: Collector → Integrator → Analyst
Final stage performs intelligent analysis using LLM and AI

3 Core Expansion Strategies

1️⃣ Data Expansion (Data Add On)

Integration of additional data sources beyond Event Messages:

Metrics: Performance indicators and metric data
Manuals: Operational manuals and documentation
Configures: System settings and configuration information
Maintenance: Maintenance history and procedural data

2️⃣ System Extension

Infrastructure scalability and flexibility enhancement:

Scale Up/Out: Vertical/horizontal scaling for increased processing capacity
To Cloud: Cloud environment expansion and hybrid operations

3️⃣ LLM Model Enhancement (More Better Model)

Evolution toward DC Operations Specialized LLM:

Prompt Up: Data center operations-specialized prompt engineering
Nice & Self LLM Model: In-house development of DC operations specialized LLM model construction and tuning

Strategic Significance

These 3 expansion strategies present a roadmap for evolving from a simple event log analysis system to an Intelligent Autonomous Operations Data Center. Particularly, through the development of in-house DC operations specialized LLM, the goal is to build an AI system that achieves domain expert-level capabilities specifically tailored for data center operations, rather than relying on generic AI tools.

Basic of Reasoning

Posted on 2025-08-292025-08-28 by lechuck park

This diagram illustrates that human reasoning and AI reasoning share fundamentally identical structures.

Key Insights:

Common Structure Between Human and AI:

Human Experience (EXP) = Digitized Data: Human experiential knowledge and AI’s digital data are essentially the same information in different representations
Both rely on high-quality, large-scale data (Nice & Big Data) as their foundation

Shared Processing Pipeline:

Both human brain (intuitive thinking) and AI (systematic processing) go through the same Basic of Reasoning process
Information gets well-classified and structured to be easily searchable
Finally transformed into well-vectorized embeddings for storage

Essential Components for Reasoning:

Quality Data: Whether experience or digital information, sufficient and high-quality data is crucial
Structure: Systematic classification and organization of information
Vectorization: Conversion into searchable and associative formats

Summary: This diagram demonstrates that effective reasoning – whether human or artificial – requires the same fundamental components: quality data and well-structured, vectorized representations. The core insight is that human experiential learning and AI data processing follow identical patterns, both culminating in structured knowledge storage that enables effective reasoning and retrieval.

The Evolution of Mainstream Data in Computing

Posted on 2025-08-212025-08-20 by lechuck park

This diagram illustrates the evolution of mainstream data types throughout computing history, showing how the complexity and volume of processed data has grown exponentially across different eras.

Evolution of Mainstream Data by Computing Era:

Calculate (1940s-1950s) – Numerical Data: Basic mathematical computations dominated
Database (1960s-1970s) – Structured Data: Tabular, organized data became central
Internet (1980s-1990s) – Text/Hypertext: Web pages, emails, and text-based information
Video (2000s-2010s) – Multimedia Data: Explosive growth of video, images, and audio content
Machine Learning (2010s-Present) – Big Data/Pattern Data: Large-scale, multi-dimensional datasets for training
Human Perceptible/Everything (Future) – Universal Cognitive Data: Digitization of all human senses, cognition, and experiences

The question marks on the right symbolize the fundamental uncertainty surrounding this final stage. Whether everything humans perceive – emotions, consciousness, intuition, creativity – can truly be fully converted into computational data remains an open question due to technical limitations, ethical concerns, and the inherent nature of human cognition.

Summary: This represents a data-centric view of computing evolution, progressing from simple numerical processing to potentially encompassing all aspects of human perception and experience, though the ultimate realization of this vision remains uncertain.

Overall Meaning

This diagram visually represents the concept that human cognitive abilities can be extended through AI tools and data analysis, enabling deeper mutual understanding between microscopic details and macroscopic patterns. It illustrates the complementary relationship where understanding small details leads to better prediction of the big picture, and understanding the big picture leads to more accurate prediction of details.

The diagram suggests that AI and data serve as amplifying tools that enhance human perception, allowing for more sophisticated analysis across different scales of observation and prediction.
