Workload Migration for Power Consumption Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power consumption of computer systems due to improved data processing performance leads to high operating expenses, necessitating an effective method for managing power consumption.
Innovation Solution
A power consumption management method that involves pre-allocating resources into non-overlapping first and second resource areas, migrating workloads from the first area to the second when certain conditions are met, and setting devices in the first area to a lower-power state, such as sleep or power-off, to reduce overall power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data processing performance is improved, then computing capability is enhanced, but power consumption increases
Solution Approach 1:
The system segments resources into multiple resource areas (first resource area, second resource area, third resource area) and divides workloads across these segments. By migrating workloads between segmented resource areas, the system can consolidate active workloads into fewer areas and power down devices in other areas, thereby reducing overall power consumption while maintaining data processing performance.
2Use of energy by moving object
If workload is concentrated in fewer resource areas, then power consumption is reduced, but system reliability may be compromised
Solution Approach 1:
The system dynamically adjusts workload distribution across resource areas based on real-time conditions. Workload migration conditions are evaluated continuously, and workloads are migrated between resource areas as needed. This dynamic approach ensures that the system can consolidate workloads to reduce power consumption when conditions permit, while maintaining the capability to redistribute workloads and ensure reliability when needed.
3Use of energy by moving object
If devices are set to lower-power state, then power consumption is reduced, but processing capacity is decreased
Solution Approach 1:
The system merges workloads from multiple resource areas into consolidated resource areas. By migrating workloads from the first resource area to the second and third resource areas, the system can set devices in the first resource area to lower-power states. The merged workloads in the remaining active resource areas maintain sufficient processing capacity while reducing overall power consumption.

AI summary
A power consumption management method. Resources such as computing resources or communication resources in the computer system include a first resource area and a second resource area. In addition, a resource provided in the first resource area includes a computing resource or a communication resource, and is used to support a workload in the first resource area. When a workload migration condition is met, the computer system may migrate a workload in the first resource area to the second resource area. According to this application, workloads in the first resource area are reduced, or there is no workload in the first resource area.
