Service Management Device Prioritizing Storage Volume I/O
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In microservice architecture, the response time of services is delayed due to the time required for writing and reading data to and from databases, as existing techniques struggle to prioritize I/O requests effectively across multiple volumes, leading to bottlenecks and prolonged response times.
Innovation Solution
A service management device that acquires execution times of programs, identifies the volume with the largest influence on response time, and sets its I/O priority higher than other volumes, ensuring faster data writing and reading operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data writing and reading operations are performed on multiple volumes without priority differentiation, then all volumes can be accessed, but the response time of the service is delayed due to I/O bottlenecks
Solution Approach 1:
The patent assigns different priority levels to different storage volumes based on their specific characteristics and the importance of data operations they handle. The service management device identifies critical volumes that have the greatest impact on service response time and grants them higher I/O priorities, while less critical volumes receive lower priorities. This local differentiation of quality (priority levels) across volumes resolves the contradiction by ensuring that time-sensitive operations on critical volumes are expedited without completely halting operations on other volumes.
Solution Approach 2:
The patent dynamically changes the priority parameter of data operations based on the identified influence of each volume on service response time. The service management device monitors and adjusts the priority levels assigned to I/O operations on different volumes, transforming the static priority system into a dynamic one that adapts to actual service needs. This parameter change enables faster response times for critical operations while maintaining overall system productivity.
2Loss of time
If I/O priority is increased for the most influential volume, then response time is reduced, but the complexity of volume management increases
Solution Approach 1:
The service management device automatically identifies which volumes have the greatest impact on service response time and autonomously assigns appropriate priority levels to I/O operations on those volumes. This self-service mechanism eliminates the need for manual configuration and continuous monitoring by system administrators. The device performs self-diagnosis and self-optimization by analyzing service execution paths and automatically adjusting volume priorities, thereby reducing response time without significantly increasing operational complexity.
Solution Approach 2:
The patent implements a feedback mechanism where the service management device continuously monitors service response time and the performance of individual volumes. Based on this feedback, the device dynamically adjusts the priority levels of I/O operations on different volumes. This closed-loop control system automatically adapts to changing service requirements and volume performance characteristics, resolving the contradiction by maintaining optimal response times through automated feedback-driven adjustments rather than complex manual management.
