# Deploying a Parallels HALB appliance

To download a Parallels HALB appliance, visit <https://www.parallels.com/products/ras/download/links/>.

On the **Download Parallels Remote Application Server** web page, scroll down to the **Download Optional Server Components** table and find the **Parallels Remote Application Server HALB Appliances** row. The row contains the following download links:

* HALB Appliance OVA
* HALB Appliance VHD
* HALB Appliance VMDK

The appliance type that you need to download depends on the hypervisor that you are using. Please follow the instructions below for your hypervisor type.

## **VMware**

For VMware, the appliance can be imported with either the OVA or zipped VMDK appliance file. If deployed via the OVA file, the VM is created already configured.

Alternatively, deployment via the VMDK file deploys the VM without preconfigured specifications. The minimum specifications for this VM are outlined below:

* One CPU
* 256 MB RAM
* One network card

## **Microsoft Hyper-V**

For Microsoft Hyper-V, the appliance is imported with the VHD file.

## **Deploying a Parallels HALB appliance**

After you download a Parallels HALB appliance, you need to import it to a hypervisor running on a separate machine connected to the same local network as Parallels RAS. For the information on how to import a virtual appliance, please consult your hypervisor documentation.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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 following URL with the `ask` and `goal` query parameters:

```
GET https://docs.parallels.com/landing/ras-admin-guide/v19-en-us/parallels-ras-19-administrators-guide/load-balancing-and-halb/high-availability-load-balancing-halb/deploying-a-parallels-halb-appliance.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

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.
