Storage Resource Load Concentration Detection in Job Nets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer systems with multiple jobs executing simultaneously, there is a risk of load concentration on a single physical storage resource, leading to potential execution time extensions or failures, as existing techniques do not adequately inform users about simultaneous access to the same storage resource.
Innovation Solution
A management system that identifies jobs likely to access the same physical storage resource simultaneously, determines the allocated resources, and notifies users of potential load concentration, allowing for proactive measures to prevent execution time extensions or failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple jobs are executed simultaneously to increase productivity, then job processing efficiency is improved, but load concentration on physical storage resources occurs causing execution time extension or failure
Solution Approach 1:
The system performs preliminary analysis before job execution to identify which jobs may access the same physical storage resources simultaneously. By detecting potential load concentration scenarios in advance, the system can notify users beforehand, allowing them to adjust job schedules or resource allocation before execution begins, thus preventing execution failures while maintaining high productivity
2Adaptability or versatility
If job nets are used to process online operations during the day and data analyses at night to increase operating ratio, then resource utilization is improved, but simultaneous access to physical storage resources may still occur within each job net
Solution Approach 1:
The system provides feedback to users about potential load concentration on physical storage resources within job nets. By analyzing the allocation relations between storage areas and physical resources, the system notifies users of jobs that may simultaneously access the same physical resources, enabling them to optimize job net configurations and resource allocation strategies to avoid harmful load concentration while maintaining flexible resource utilization

AI summary
An exemplary management system identifies, based on first information indicating a job net defining an execution order of jobs executed by the host computer, jobs having possibility to be executed simultaneously at the job net. The management system identifies, based on second information indicating an execution content of each of the jobs, storage areas at the host computer for storing data of the jobs having possibility to be executed simultaneously. The management system identifies, based on third information indicating an allocation relation between the data storage areas of the host computer and resources of the storage apparatus, a resource of the storage apparatus allocated to each of the identified storage areas. The management system determines a physical resource of the storage apparatus, allocated to at least two of the storage areas of the identified storage areas, has possibility to be used simultaneously by at least two jobs.
