Refer to the sizing guide with details on the default parity count chosen for different erasure stripe sizes [here](https://github.com/minio/minio/blob/master/docs/distributed/SIZING.md)

Refer to sizing guide for more understanding on default values chosen depending on your erasure stripe size [here](https://github.com/minio/minio/blob/master/docs/distributed/SIZING.md). Parity settings can be changed using [storage classes](https://github.com/minio/minio/tree/master/docs/erasure/storage-class).
