UPS and Non-UPS Edge Node Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge computing solutions face challenges in managing power supply and consumption, particularly in power-constrained environments, where not all resources are uninterruptible power supply (UPS) compliant, leading to inefficiencies and potential service disruptions during power or cooling outages.
Innovation Solution
A power management system that differentiates between UPS and non-UPS compliant resources, dynamically adjusting power delivery and resource allocation based on service criticality, allowing for smart power delivery and throttling to maintain service levels during outages, and enabling power usage-based billing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If edge computing resources are deployed closer to network access points to reduce latency, then response time is improved, but power management complexity increases due to mixed UPS and non-UPS compliant resources
Solution Approach 1:
The system segments computing resources into distinct UPS-compliant and non-UPS-compliant categories, allowing differentiated power management strategies. This segmentation enables the system to maintain simple power management for non-critical resources while ensuring continuous power supply for critical services during outages.
Solution Approach 2:
Different power management policies are applied to different resource types based on their UPS compliance status. UPS-compliant resources receive guaranteed power supply for critical services, while non-UPS resources follow standard power management, creating locally optimized power delivery tailored to each resource's capabilities and service requirements.
2Reliability
If all resources are made UPS compliant to ensure continuous operation during outages, then reliability is improved, but cost and resource utilization efficiency worsen
Solution Approach 1:
Instead of making all resources UPS-compliant (excessive action), the system applies UPS compliance only to the extent necessary for critical services. Non-critical services run on standard power resources, optimizing resource utilization while maintaining reliability where needed.
Solution Approach 2:
The system changes the power delivery parameter dynamically based on service criticality and outage conditions. During normal operation, standard power management is applied to all resources. During outages, the system adjusts power delivery to guarantee continuous operation for critical services while allowing non-critical services to shut down or reduce operation.
3Loss of energy
If power is throttled in non-UPS compliant resources during outages to reduce consumption, then energy efficiency is improved, but service level maintenance becomes difficult
Solution Approach 1:
The system dynamically adjusts power delivery based on real-time outage conditions and service criticality. During normal operation, full power is supplied to maintain service levels. During outages, the system dynamically throttles power to non-UPS resources while maintaining guaranteed power supply to UPS-compliant critical services, optimizing the balance between energy efficiency and service level maintenance.

AI summary
Some examples provide for uninterruptible power supply form (UPS) resources and non-UPS resources to be offered in a composite node for customers to use. For a workload run on the composite node, monitoring of non-UPS resource power availability, resource temperature, and/or cooling facilities can take place. In the event, a non-UPS resource experiences a power outage or reduction in available power, temperature that is at or above a threshold level, and/or cooling facility outage, monitoring of performance of a workload executing on the non-UPS resource can take place. If the performance is acceptable and the power available to the non-UPS resource exceeds a threshold level, the supplied power can be reduced. If the performance experiences excessive levels of errors or slows unacceptably, the workload can be migrated to another non-UPS or UPS compliant resource.
