VM Scale Booster Prerequisites

To install the Accops VM Scale Booster setup on a Windows desktop system, the following prerequisites must be fulfilled:

Hardware Requirements

Accops VM Scale Booster can be installed on Windows machines (physical or virtual) with the following minimum configuration:

Minimum Server Configurations:

  • Minimum 4 GB RAM

  • 2 vCPUs

  • 10 GB of free space on the installation disk for installation, dependencies, and post-installation management files.

Note

Actual server sizing should be determined by the anticipated user load and user profiles, including application types and browser instances.

Where to install VM Scale Booster

VM Scale Booster is typically deployed to reduce communication overhead with agents on desktop VMs; therefore, placing it on the same server as the Controller defeats its purpose. It is recommended to install it on a separate Windows server from the HyWorks Controller.

However, as needed for deployment, VM Scale Booster can still be deployed on HyWorks Controllers. When configuring VM Scale Booster settings, the load balancer must be placed in front of the message queues, and its address must be configured on the HyWorks Controller.

Supported Operating Systems

Accops VM Scale Booster works fine on all Windows servers that HyWorks Controller also supports.

Important Software Requirements (RabbitMQ)

Accops VM Scale Booster relies on RabbitMQ to support its features, such as desktop agents pushing updates to queues and directly to the HyWorks Controller database. This section will provide detailed information on installing and configuring RabbitMQ and its dependencies.

This section of the document provides the latest version(s) of RabbitMQ and Erlang OTP supported by HyWorks modules that require these components.

Important

About RabbitMQ and Erlang/OTP

  • It is highly recommended to keep RabbitMQ and Erlang/OTP interoperable, following the guidelines. Refer to Erlang Version Requirements | RabbitMQ for details.

  • Not all minor versions are being tested, so it is highly recommended to use the mentioned minor versions.

  • Please check the EOL of RabbitMQ and supported Erlang/OTP versions.

  • Important points to note for ASP.NET Core and .NET Desktop Runtime

    • Download and install only the recommended major version. You can select the highest minor version available. For example, if the recommended version is v8.0., then use 8.0.x. Do not use 8.1.x* or higher.

    • The official site recommends installing the desktop runtime by default, which includes the .NET Runtime, so explicit installation of .NET Runtime should not be necessary.
