Health Data Storage Using Selective Persistent Writes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storing health data files periodically in non-volatile memory reduces the usable life of computing devices due to the limited number of data writes these memories can handle.
Innovation Solution
A peer computing device transfers health data files to volatile memory for analysis and storage, moving them to non-volatile memory only when necessary, such as after an unexpected shutdown or error state, thereby reducing the frequency of writes to persistent storage.

Engineering Contradiction Analysis
1Reliability
If health data files are stored periodically in non-volatile memory, then health data is preserved for diagnostic purposes, but the usable life of the computing device is reduced due to limited write cycles
Solution Approach 1:
The system performs preliminary analysis of health data in volatile memory before deciding whether to write to non-volatile memory. By evaluating the health state and determining if storage is necessary beforehand, the system avoids unnecessary write operations, thereby preserving non-volatile memory write cycles while ensuring critical health data is captured when needed for diagnostics
Solution Approach 2:
The system introduces volatile memory as an intermediary between health data generation and non-volatile memory storage. Health data is first written to volatile memory, analyzed, and only selectively transferred to non-volatile memory when diagnostic storage is warranted. This intermediary approach reduces the frequency of writes to non-volatile memory while maintaining the ability to preserve critical health information

AI summary
Example implementations relate to computer data storage. In some examples, a controller of a first device receives a first data file comprising operating health information for a second device. The controller of the first device stores the first data file in a memory of the first device, and determines whether the second device is in operating normally. Further, in response to a determination that the second device is not operating normally, the controller of the first device moves the first data file from the memory of the first device to a persistent storage of the first device.
