Solution Overview

Problem

Traditional network architectures face challenges with increasing computational and thermal density, leading to component failure and maintenance issues due to the concentration of multiple processing units on a single server, necessitating the replacement of entire server racks when one component fails.

Innovation Solution

Implementing disaggregated server devices with isolated GPUs and separate switch modules, allowing for modular, scalable networking chassis that minimize density concerns and enable easy maintenance by isolating switching hardware from computational hardware.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple processing units are concentrated on a single server to increase computational density, then computational power is improved, but thermal density increases leading to component failure and maintenance issues

Engineering Contradiction:

Improvecomputational powerVSAvoidthermal density

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

The patent segments the server system into multiple independent server devices, each handling specific computational tasks. Instead of concentrating all processing units in one server, the workload is distributed across several servers (e.g., server 102, server 104, server 106), reducing thermal density in each individual server while maintaining overall computational power.

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple processing units are concentrated on a single server to increase computational density, then computational power is improved, but reliability decreases due to component failure requiring replacement of entire server racks

Engineering Contradiction:

Improvecomputational powerVSAvoidsystem reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system is segmented into multiple independent server devices within a chassis, where each server can be independently replaced. If one server fails, only that specific server needs replacement rather than the entire rack, improving reliability while maintaining computational power through the remaining servers.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the architectural parameter from centralized multi-processing-unit servers to distributed single-processing-unit servers. This parameter change allows for easier replacement and maintenance of individual servers, improving system reliability while preserving overall computational capacity through the distributed architecture.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If switching hardware is integrated with computational hardware on the same server, then device complexity is reduced, but maintenance difficulty increases when switching components need repair

Engineering Contradiction:

Improvehardware integrationVSAvoidmaintenance difficulty

Core Design Contradiction:

Device complexityVSEase of repair

Solution Approach 1:

The patent segments switching hardware into separate, dedicated switch modules (e.g., switch module 112, switch module 114) independent from computational server devices. This segmentation allows switching components to be maintained, repaired, or replaced without affecting computational servers, and vice versa, improving ease of repair while managing device complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Switching hardware is extracted from the computational server devices and placed into separate switch modules. This extraction isolates switching functions from computational functions, allowing independent maintenance of each component type without requiring disassembly or interference with the other, thereby improving ease of repair.

Inventive Principle:

Principle #2Taking out (Extraction)

4Area of stationary object

If server density is increased to improve space utilization, then area efficiency is improved, but thermal management becomes more difficult and component failure risk increases

Engineering Contradiction:

Improvespace utilizationVSAvoidthermal management

Core Design Contradiction:

Area of stationary objectVSTemperature

Solution Approach 1:

The patent uses segmentation to distribute processing units across multiple servers within the same chassis space. This segmentation reduces thermal density in each server while maintaining high area efficiency, as the chassis accommodates multiple lower-power servers rather than fewer high-power servers, improving thermal management without sacrificing space utilization.

Inventive Principle:

Principle #1Segmentation
