Storage Control Apparatus Compresses Management Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage management systems face challenges in reducing the time required for communication of management information between storage apparatus and management apparatus, particularly when power is off or communication is interrupted, leading to accumulation of operation substances and increased data transmission time.
Innovation Solution
A storage control apparatus that compresses management information by identifying and deleting non-influential operations from the operation history, allowing for minimal data transmission while maintaining accurate representation of storage region configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all operation substances are transmitted to synchronize management information, then synchronization accuracy is improved, but transmission time increases significantly
Solution Approach 1:
The patent extracts only the necessary operation substances that actually influence storage region configurations from the complete operation history. By identifying and transmitting only these relevant operations rather than all operations, the system achieves synchronization accuracy while significantly reducing transmission time and data volume.
Solution Approach 2:
The patent applies local quality by differentiating between operations based on their influence on storage region configurations. Operations that affect configurations are marked and transmitted with higher priority, while non-influential operations are filtered out. This selective approach ensures that only locally relevant information is transmitted, optimizing both accuracy and efficiency.
2Loss of information
If operation history is retained completely for synchronization, then data completeness is improved, but data volume increases
Solution Approach 1:
The patent extracts only the essential operation records that contain configuration-changing information from the complete operation history. By removing redundant non-influential operations, the system maintains data completeness for synchronization purposes while significantly reducing the volume of data that needs to be stored and transmitted.
Solution Approach 2:
Instead of retaining all operations and filtering at transmission time, the patent inverts the approach by pre-processing the operation history to identify and mark only influential operations. This inversion allows the system to maintain a compact representation of operation history that contains all necessary information for synchronization without unnecessary data bloat.
3Reliability
If full management information is synchronized periodically, then synchronization reliability is improved, but communication load increases
Solution Approach 1:
The patent extracts only the subset of management information that represents actual configuration changes from the complete operation history. By transmitting only these extracted relevant operations during periodic synchronization, the system maintains synchronization reliability while dramatically reducing the communication load and energy consumption associated with data transmission.
Solution Approach 2:
The patent applies partial action by transmitting only the necessary portion of management information required for synchronization rather than the complete set. This partial transmission approach is sufficient to maintain reliability because it includes all configuration-affecting operations, while avoiding the excessive communication load that would result from transmitting redundant non-influential operations.
Data Source
AI summary
A storage control apparatus including a memory and a processor coupled to the memory and the processor configured to execute a process, the process including storing, in the memory, management information including an operation history for a storage region of a storage device, specifying at certain timing, from the management information, a first operation that has been executed to set a configuration of the storage region to a configuration at the certain timing, determining a second operation from among operations, in the management information, that precede the execution of the first operation and that target the storage region, deleting the second operation from the management information, and transmitting the management information after the deletion to a management apparatus that manages a state of the storage region of the storage device.
