By default, MinIO shards the objects across N/2 data and N/2 parity drives. Though, you can use [storage classes](https://github.com/minio/minio/tree/master/docs/erasure/storage-class) to use a custom configuration. We recommend N/2 data and parity blocks, as it ensures the best protection from drive failures.

### 2. Configure WSO2

Once WSO2 is up and running, configure WSO2 to generate Self contained id_tokens. In OAuth 2.0 specification there are primarily two ways to provide id_tokens

export MINIO_STORAGE_CLASS_STANDARD=EC:3
export MINIO_STORAGE_CLASS_RRS=EC:2
```

Storage class can also be set via `mc admin config` get/set commands to update the configuration. Refer [storage class](https://github.com/minio/minio/tree/master/docs/config#storage-class) for
more details.
