# Groupes de disponibilité SQL Server Always On

Les clients principaux de Remote Desktop Manager et de Devolutions Server sont conçus avec la plateforme .NET. Par conséquent, leurs capacités liées aux bases de données dépendent souvent des bibliothèques .NET sous-jacentes.

Par conséquent, les groupes de disponibilité pris en charge dépendent des fonctionnalités offertes par le pilote de base de données lui-même. Les types suivants sont tous pris en charge :

* Intention de l'application
* Basculement multi-sous-réseau
* Basculement multi-sous-réseau : basculement plus rapide du terminal d'un sous-réseau unique
* Basculement multi-sous-réseau : résolution des instances nommées pour les instances en grappe SQL
* Routage en lecture seule

## 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.devolutions.net/rdm/fr/knowledge-base/knowledge-base-articles/sql-server-always-on-availability-groups.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.
