Solution Overview

Problem

Current blade server architectures face limitations in communications between individual blades due to bottlenecks in midplane bus connections and non-configurable point-to-point communications, which restrict flexibility and scalability in resource allocation.

Innovation Solution

A supplemental optical communications system with configurable point-to-point pathways and pivotable mirrors within the blade server enclosure allows for dynamic or static configuration of optical connections between blade servers, enabling flexible resource allocation without requiring physical re-arrangement of blades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If midplane bus connections are used for blade server communications, then system integration is simplified, but communication bandwidth and speed are limited

Engineering Contradiction:
Improvecommunication speedVSAvoidcommunication architecture complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent segments the communication pathway by introducing dedicated optical communication channels between blade pairs, separating high-speed point-to-point communication from the general-purpose midplane bus. This allows critical communications to bypass the bus bottleneck while maintaining system integration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces optical transceivers and optical cables as intermediary components between blades, enabling high-speed communication without direct electrical connection through the midplane bus. The optical intermediary bypasses the electrical bus limitations while maintaining compatibility with the existing blade architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If dedicated point-to-point connections are implemented between blades, then communication speed improves, but device complexity and installation difficulty increase

Engineering Contradiction:
Improvecommunication speedVSAvoidinstallation ease
Core Design Contradiction:
SpeedVSEase of manufacture

Solution Approach 1:

The patent designs universal optical transceiver modules that can be installed in any blade slot position, allowing the same component to serve multiple configuration needs. The optical pathway components are designed to work with any blade pair, eliminating the need for custom wiring for each connection scenario.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements dynamically reconfigurable optical connections where transceivers can be activated or deactivated based on communication needs. The system allows flexible pairing of blades through software configuration rather than fixed physical connections, enabling adaptive topology changes without physical reinstallation.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If physical re-arrangement of blades is required for reconfiguration, then communication pathways are fixed, but flexibility and scalability are reduced

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamically reconfigurable optical connections where transceivers can be activated or deactivated based on communication needs. The system allows flexible pairing of blades through software configuration rather than fixed physical connections, enabling adaptive topology changes without physical reinstallation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces the mechanical reconfiguration process (physically moving blades) with an optical/electronic control system. The optical transceivers are controlled by software or management systems, allowing logical reconfiguration of communication pathways without any physical movement of blade components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 1:

The patent merges the optical communication pathway with the existing blade server enclosure structure, integrating optical transceivers into blade slots and routing optical cables through existing pathways. This consolidation adds optical capability without requiring separate standalone optical infrastructure, reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent designs universal optical transceiver modules that can be installed in any blade slot position, allowing the same component to serve multiple configuration needs. The optical pathway components are designed to work with any blade pair, eliminating the need for custom wiring for each connection scenario.
