### 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
- 12 * 12 = 144 drives pool2

Вы также можете использовать `from starlette.responses import Response` или `from starlette.responses import JSONResponse`.

**FastAPI** предоставляет те же самые `starlette.responses` как `fastapi.responses` — для вашего удобства как разработчика. Но большинство доступных классов ответов поступают напрямую из Starlette.
