Solution Overview

Problem

Data processing systems with power supply free chassis face challenges in ensuring sufficient power supply to hardware components, leading to suboptimal performance and potential interruptions, which can hinder the provision of desired computer-implemented services.

Innovation Solution

Implementing a power management system that assesses power availability and makes workload placement decisions based on power availability assessments, utilizing external power components to manage power distribution efficiently, including redundancy and health monitoring of rail-mounted power systems to prevent overdraw and optimize performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external power supplies are used to provide power to hardware components in power supply free chassis, then power availability is improved, but power distribution complexity increases

Engineering Contradiction:
Improvepower availabilityVSAvoidpower distribution complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A power management system acts as an intermediary between external power supplies and hardware components, managing power distribution centrally through power management modules that communicate with a controller, thereby reducing the complexity of direct power connections to each component

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The power management system provides multiple functions including power availability assessment, workload placement decisions, health monitoring, and throttling control through a unified framework, eliminating the need for separate systems for each function

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

2Reliability

If power management system implements comprehensive monitoring and control, then workload completion likelihood is improved, but system complexity increases

Engineering Contradiction:
Improveworkload completion likelihoodVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The power management system continuously monitors power availability, component health status, and workload performance, using this feedback information to dynamically adjust workload placement and power distribution decisions, thereby improving reliability through adaptive control

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary assessments of power availability and component health before making workload placement decisions, and implements preventive throttling measures before power issues occur, reducing the need for complex reactive control mechanisms

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If power is throttled to prevent overdraw, then power supply stability is improved, but performance of throttled chassis deteriorates

Engineering Contradiction:
Improvepower supply stabilityVSAvoidchassis performance
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The system applies partial throttling only to the extent necessary to prevent power overdraw, rather than completely disabling affected chassis, thereby maintaining sufficient performance while ensuring power supply stability through controlled power reduction

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The throttling level is dynamically adjusted based on real-time power availability assessments and workload requirements, allowing the system to optimize the balance between power stability and performance rather than using fixed throttling thresholds

Inventive Principle:
Principle #15Dynamics

AI summary

Methods, systems, and devices for managing performance of workloads by hardware components housed in a power supply free chassis of a rack system are disclosed. To manage the performance, an aggregate power draw of power supplies of a rail mounted power system may be obtained and a maximum power output of a power distribution unit of the rail mounted power system may be identified. Based on the maximum power output and the aggregate power draw, a determination may be made regarding whether the aggregate power draw exceeds the maximum power output. If the maximum power output is exceeded, each chassis that draws power from any of the power supplies may be ranked with regard to one another based on priority rankings to obtain a rank ordering of the chassis.
