### Does IONOS DBaaS use or provide support for an In-Memory DB Sentinel?

Unfortunately, IONOS does not use or provide support for an In-Memory DB Sentinel. However, we offer monitoring and automatic failover features.

### Can I customize my cluster's Block Storage capacity?

The provisioned Block Storage in an In-Memory DB cluster depends on the amount of RAM configured and the data persistence mode selected. As a result, you cannot select the amount of Block Storage for your cluster; instead, they are calculated automatically following a pre-determined ratio. For more information, see [<mark style="color:blue;">Determine Provisioned Block Storage in an In-Memory DB Cluster</mark>](/cloud/~/revisions/UIHN5vc23LyGCaurOi2f/databases/in-memory-db/overview/data-persistence.md#determine-provisioned-block-storage-in-an-in-memory-db-cluster).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ionos.com/cloud/~/revisions/UIHN5vc23LyGCaurOi2f/databases/in-memory-db/in-memory-db-faqs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
