Performance Information Management System Storage Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of regularly acquiring and storing performance information leads to a high number of random accesses when retrieving data for a specific resource over a period, resulting in increased access time due to the separation of performance information in storage areas.
Innovation Solution
A performance information management system that allocates initial storage areas of varying capacities to each monitoring target, detects storage area depletion, and allocates additional consecutive storage areas to store performance information sequentially, reducing the need for random access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If performance information is sequentially stored in a table as it is acquired, then performance information can be stored in chronological order, but a large number of random accesses occur when reading performance information for a specific resource
Solution Approach 1:
The patent segments the storage structure by creating separate circular buffer areas for each monitoring target (resource) rather than using a single sequential table. Each resource has its own dedicated storage area where data is appended sequentially, eliminating the need to search through unrelated entries and reducing random access operations when reading performance information for a specific resource.
2Quantity of substance
If performance information from different resources is stored in adjacent storage areas, then storage space is efficiently utilized, but performance information from a single resource is separated into non-adjacent areas
Solution Approach 1:
The patent divides the storage structure into multiple segmented areas, with each segment dedicated to a specific monitoring target. This segmentation allows efficient storage space utilization while maintaining data locality for each resource, as each resource's performance information is stored contiguously in its own segment rather than being scattered throughout the storage structure.
Solution Approach 2:
The patent transitions from a one-dimensional sequential storage approach to a multi-dimensional structure where storage is organized by resource identity. Each resource has its own dimensional space (circular buffer area), allowing simultaneous efficient storage utilization and easy access to any resource's complete performance history without interfering with other resources.
3Loss of information
If a large number of random accesses are performed to read performance information, then performance information can be retrieved, but the access time increases significantly
Solution Approach 1:
The patent performs preliminary organization of data during the storage phase by appending each resource's performance information to its dedicated circular buffer area in chronological order. This preliminary action ensures that when reading is required, all necessary data for a specific resource is already contiguous and sequentially arranged, eliminating the need for random access operations and significantly reducing retrieval time.
