HIGH-PERFORMANCE, BLOCK-LEVEL FAIL ATOMICITY ON BYTE-LEVEL NON-VOLATILE MEDIA - A simplified explanation of the abstract
This abstract first appeared for US patent application 17966737 titled 'HIGH-PERFORMANCE, BLOCK-LEVEL FAIL ATOMICITY ON BYTE-LEVEL NON-VOLATILE MEDIA
Simplified Explanation
The patent application describes a technique for achieving block-level fail atomicity on byte-level non-volatile media by using an offset table and application data to store file content.
- An offset table is used to store multiple entries, each associated with a different offset value and storing a logical block address (LBA) that references a location in the application data.
- When a request is received to update a file, the corresponding entry in the offset table is identified, a free LBA is found, the free LBA is replaced with the original LBA, the input buffer is written to the location referenced by the free LBA in the application data, and the free LBA is added to the entry.
Potential Applications
- Data storage systems
- File systems
Problems Solved
- Ensuring atomicity of block-level updates on non-volatile media
- Efficiently managing data updates in file systems
Benefits
- Improved data integrity
- Enhanced performance in file operations
Potential Commercial Applications
Enhanced Data Storage Systems for Improved Performance
Possible Prior Art
There may be existing techniques for managing data updates in file systems, but the specific approach described in the patent application may be novel.

Original Abstract Submitted
Techniques are provided for block-level fail atomicity on byte-level non-volatile media. In one technique, an offset table and application data that stores content of a file are stored for a file. The offset table includes multiple entries, each entry being associated with a different offset value and storing a logical block address (LBA) that references a location in the application data. In response to receiving a request, that includes an input buffer and an offset value, to update the file: (a) an entry, in the offset table, that corresponds to the offset value and comprises a first LBA is identified; (b) a second LBA that is considered free is identified; (c) the second LBA is replaced with the first LBA; (d) the input buffer is written to a location, in the application data, that the second LBA references; and (e) the second LBA is added in the entry.
