Storage Management Computer Load Balancing Ownership Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer systems face challenges in managing load imbalances between processors in storage devices, as current techniques do not adequately consider the influence of ownership changes on operational management and may result in unintended changes.
Innovation Solution
A computer system and method that includes a management computer to collect usage information, detect load imbalances, generate plans for ownership changes, and execute these plans while estimating the influence of the change process, ensuring minimal disruption to operational management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ownership change process is executed to resolve load imbalance, then load distribution is improved, but operational management stability deteriorates due to unintended changes
Solution Approach 1:
The system performs preliminary actions by collecting usage information and detecting events before executing ownership changes. The plan generation unit creates a change plan that is reviewed and approved before actual execution, preventing unintended changes while ensuring load imbalance is resolved.
Solution Approach 2:
The system implements feedback mechanisms by monitoring usage information continuously and detecting events that trigger ownership changes. The plan execution unit executes changes based on detected events, and the system continues to monitor the effects, creating a closed-loop control system that maintains operational stability.
2Speed
If ownership change process is executed automatically, then response speed to load imbalance is improved, but operational management control deteriorates due to lack of human oversight
Solution Approach 1:
The system generates a change plan in advance that includes details of the ownership change. This plan is then reviewed and approved by operational management before execution, combining automated speed with human oversight and control.
Solution Approach 2:
The plan generation unit and plan execution unit act as intermediaries between automated detection and actual ownership changes. These components translate detected events into structured change plans that can be reviewed and approved, serving as a bridge between automation and human control.
3Reliability
If ownership change process is delayed to avoid operational disruption, then operational management stability is improved, but load imbalance resolution is delayed
Solution Approach 1:
The system prepares change plans in advance with full documentation of the proposed ownership changes. This preliminary preparation allows for quick execution once approved, reducing the actual disruption time while maintaining operational stability through proper planning.
Solution Approach 2:
The system enables rapid execution of pre-approved change plans when events are detected, skipping unnecessary delays. The plan execution unit can quickly implement changes that have already been validated, resolving load imbalance efficiently while maintaining operational stability.

AI summary
The computer system includes one or more storage devices and a management computer, the management computer includes an information collection unit, an event detection unit, a plan generation unit, and a plan execution unit. The plan generation unit determines a target volume of a change process of a right of control in a plan, a processor of a change source of the right of control, and a processor of a change destination of the right of control, estimates an influence by a change process of the right of control in the plan, and the plan execution unit determines execution time of the plan based on the estimation of the influence and the operation information of the storage devices. As a result, in consideration of the influence by an ownership change process, while the influence applied to usage of a computer system is suppressed, the ownership change process is executed.
