Cohesity has filed a patent for a method that involves generating data and parity stripes using data chunks stored in a write-ahead log. These stripes are then stored on different storage devices and associated together under a data protection grouping container.

Erasure coding method for data protection in storage devices
A recently filed patent (Publication Number: US20230315303A1) describes a method for data protection using erasure coding. The method involves generating multiple data stripes and parity stripes based on an erasure coding configuration. These stripes are created using data chunks stored in a write-ahead log. The data stripes and parity stripes are then stored on different storage devices and associated together under a data protection grouping container.
The method also includes removing the data chunks from the write-ahead log and ingesting source data from a source system. The source data can be chunked into data chunks or received as pre-existing data chunks from the source system. The data chunks are stored in the write-ahead log and deduplicated during the process of generating the data stripes and parity stripes.
The patent also describes additional features such as determining the size of data chunks remaining in the write-ahead log and maintaining the erasure coding configuration based on this threshold size. If the threshold size is not met, the method includes waiting for a threshold period of time or selecting an alternate erasure coding configuration with fewer data stripes or smaller data stripe size.
The method further involves updating metadata that enables the location of the data chunks. This includes selecting a data chunk from the data stripes, checking if the corresponding chunk metadata data structure has been updated, and updating the chunk file metadata data structure accordingly.
In addition to the method, the patent also includes a computer program product embodied in a non-transitory computer-readable medium and a system comprising a processor and memory configured to execute the method.
Overall, this patent presents a method for data protection using erasure coding, where data stripes and parity stripes are generated based on an erasure coding configuration and stored on different storage devices. The method includes various features such as deduplication, threshold size determination, metadata updating, and the option to select alternate erasure coding configurations.
