An additional header `X-Minio-Replication-Delete-Status` is returned which would show `PENDING` or `FAILED` status if the replication is still not caught up.

### Transition Status

MinIO specific extension header `X-Minio-Transition` is displayed on `HEAD/GET` to predict expected transition date on the object. Once object is transitioned to the remote tier,`x-amz-storage-class` shows the tier name to which object transitioned. Additional headers such as "X-Amz-Restore-Expiry-Days", "x-amz-restore", and "X-Amz-Restore-Request-Date" are displayed when a object is under restore/has been restored to local MinIO cluster.

### There are no limits on how many server pools can be combined

```
minio server http://host{1...32}/export{1...32} http://host{1...12}/export{1...12}
```

In above example there are two server pools

- 32 * 32 = 1024 drives pool1
