Solution Overview

Problem

In enterprise computing applications with modular information handling systems, determining appropriate load reduction actions during power capacity excursions is challenging, leading to potential full chassis shutdown, loss of access to offline nodes, and loss of unsaved data due to insufficient power capacity.

Innovation Solution

A method and system that monitor power capacity, comparing it to minimum and threshold levels to trigger power consumption reduction and operational state changes, ensuring continued operation of critical components by reducing power usage or switching to a minimal operational state when power capacity falls below required levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If power capacity is insufficient to support all modular information handling systems, then full chassis shutdown occurs, but this results in loss of access to offline nodes and loss of unsaved data

Engineering Contradiction:
Improvesystem availabilityVSAvoiddata loss
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system segments the modular information handling systems into different operational states (full operation, reduced power consumption, minimal operational state) based on power capacity levels. Each node can be independently controlled to operate in the appropriate state, allowing critical systems to remain accessible while non-critical systems are scaled back, preventing complete chassis shutdown and data loss.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes operational parameters (power consumption levels, operational states) of modular information handling systems dynamically based on available power capacity. By adjusting these parameters rather than simply shutting down, the system maintains accessibility to critical nodes while adapting to power constraints, thereby preventing data loss and maintaining system availability.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If power capacity is reduced to maintain critical operations, then system availability is improved, but power consumption must be reduced

Engineering Contradiction:
Improvesystem availabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the operational state of modular information handling systems based on real-time power capacity monitoring. When power capacity drops below the first minimum power capacity, the system transitions affected nodes from full operation to reduced power consumption state, and when capacity drops further below the threshold, transitions to minimal operational state. This dynamic adaptation maintains system availability for critical operations while automatically reducing overall power consumption to match available capacity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system applies partial action by selectively maintaining full operation for critical modular information handling systems while reducing or minimizing operation for non-critical systems. This selective approach ensures that essential operations continue with adequate power while non-essential operations are scaled back, achieving the balance between maintaining availability and reducing power consumption.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If multiple operational states are implemented for power management, then power capacity utilization is optimized, but system complexity increases

Engineering Contradiction:
Improvepower capacity utilizationVSAvoidoperational state management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments power capacity management into distinct thresholds and operational states: full operation (above first minimum power capacity), reduced power consumption state (between first minimum and threshold), and minimal operational state (below threshold but above second minimum). This segmentation provides clear, manageable boundaries for decision-making, optimizing power capacity utilization while keeping the control logic structured and understandable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements continuous monitoring of power capacity and uses this feedback to automatically adjust operational states of modular information handling systems. The monitoring component provides real-time information about power capacity levels, and the system responds by transitioning nodes between operational states based on predefined thresholds, creating a closed-loop control system that optimizes power utilization without requiring complex manual management.

Inventive Principle:
Principle #23Feedback
