# Single Farm with Two RD Session Hosts
This scenario can be implemented by an organization that needs to load-balance published applications and desktops between two RD Session Hosts. For high availability, a secondary RAS Connection Broker and RAS Secure Gateway should be installed on the second server.
## **Installation Notes**
The components on the primary RD Session Host (where the primary RAS Connection Broker is installed) are installed using the Parallels RAS installer (standard installation).
The components on the secondary RD Session Host are push-installed from the RAS console.

## 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.parallels.com/landing/ras-reference-architecture/deployment-scenarios/parallels-ras-deployment-scenarios/single-farm-with-two-rd-session-hosts.md?ask=&goal=
```
`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.
