1 Introduction

Wyse® Virtual Desktop Accelerator (VDA) is a software product that, when used with Wyse thin clients and supported PCs, provides an “accelerated” user experience on remote desktop sessions with high round-trip delay between the server and client. By accelerating the remote desktop protocols by a factor of up to 3 times on certain networks, a Wyse VDA session with a server located thousands of miles from your client “feels” similar to a non-accelerated session with a server located just a few hundred miles from your client.

Built for use on high-bandwidth high-latency networks that are prone to packet loss situations, primary use cases for Wyse VDA include:• Datacenter Consolidation• Desktop Cloud Computing• Remote Off-Shore Desktop Computing

3 Installing and Configuring the Server SoftwareThis chapter provides the detailed procedures you must complete to install and configure the Wyse VDA server software. Although you can select custom installation configurations during the installation, it is recommended that you use the default configurations.

NoteBe sure you have completed all pre-installation requirements as described in "Supported Platforms and Networks" before you begin installing the server software.

About Evaluation and Production InstallationsDuring installation of the server software you can choose either an evaluation or a production installation. The evaluation installation allows you to use the full services of Wyse VDA for a period of up to 30 days. After your evaluation period expires, you must obtain a production license and upgrade your installation to continue to use the product.

To upgrade your evaluation installation, simply obtain a production license from Wyse and re-install the software using the production license. For standard installations, use the Modify option during re-installation (for installation guidelines, refer to "Performing a Standard Installation on the Server"). For silent installations, uninstall the software as described in "Performing a Silent Uninstallation on the Server," and then re-install the software using the production license .txt file as described in "Performing a Silent Installation on the Server."

NoteIf you fail to upgrade within the evaluation period (that is, your evaluation period expires), your Wyse VDA service will stop working until you upgrade to a production installation. To use the product without interruption, be sure to upgrade your evaluation installation before it expires.

6 Chapter 3

Installing the Wyse VDA Server SoftwareYou can install the Wyse VDA server software using either the standard installation mode or the silent installation mode. The standard mode will prompt you for input during the installation process (see "Performing a Standard Installation on the Server"). The silent mode will not prompt you for input during the installation process and performs a complete “typical” installation of the product (see "Performing a Silent Installation on the Server").

NoteBefore a production installation, be sure you have obtained your Wyse VDA production license. During your production installation you will need to use this license. Evaluation installations do not require a license.

Performing a Standard Installation on the ServerUse the following guidelines:

1. Uninstall any existing Wyse VDA server software as described in "Uninstalling the Wyse VDA Server Software."

2. Download the Wyse VDA server software from the Wyse Web site at www.wyse.com. Click Support | Downloads, expand the list next to Please Choose Your Product (Active), select Wyse VDA, and then click Search. Click the file name next to Wyse Virtual Desktop Accelerator to download the software (Wyse Virtual Desktop Accelerator Server.msi) to the server where you will install the software.

3. Double-click WYSE Virtual Desktop Accelerator Server.msi to open and use the installation wizard (the installation wizard guides you through the installation process).

4. You must read and accept the terms and conditions in the license agreement before the installation process installs the software.

5. During the installation process you will be prompted to select the type of installation you want (evaluation or production), be sure to select the option you need as described in "About Evaluation and Production Installations," and then click Next to continue the installation wizard.

NoteBy default, the required files are installed inC:\Program Files\Wyse\VDA. However, you can select a different location by using Change when prompted for the destination folder.

6. After the installation is complete, click Finish. Wyse VDA server software is enabled by default. For information on configuring Wyse VDA software, refer to "Configuring the Wyse VDA Server Software."

Installing and Configuring the Server Software 7

Performing a Silent Installation on the ServerUse the following guidelines:

NoteBefore a production installation, be sure you have obtained your Wyse VDA production license .txt file (not a license key). During your production installation you will need to use this license .txt file. Evaluation installations do not require a license.

1. Uninstall any existing Wyse VDA server software as described in "Uninstalling the Wyse VDA Server Software."

2. Download the Wyse VDA server software from the Wyse Web site at www.wyse.com.

Click the file name next to Wyse Virtual Desktop Accelerator to download the software (Wyse Virtual Desktop Accelerator Server.msi) to the server where you will install the software.

3. Open a Command Prompt window.

4. Navigate to the directory where the WYSE Virtual Desktop Accelerator Server.msi file is located.

5. At the command prompt, use the following guidelines: • Silent installation for evaluation, enter:

C:\>msiexec /i "<path where msi is located>\WYSE Virtual Desktop Accelerator Server.msi" /q ALLUSERS="1"

• Silent installation with production license .txt file, enter:C:\>msiexec /i "<path where msi is located>\WYSE Virtual Desktop Accelerator Server.msi" /q ALLUSERS="1" LIC_PATH=”path where txt file is located\lic.txt"

After the installation is complete, Wyse VDA server software is enabled by default. For information on configuring Wyse VDA software, refer to "Configuring the Wyse VDA Server Software."

8 Chapter 3

Configuring the Wyse VDA Server SoftwareAfter the installation is complete, Wyse VDA server software is enabled by default (Wyse VDA status in the Services applet of the Windows Administrative Tools will show as Started). However, you can configure the server software for optimal performance according to your needs. For example, you configure the server communication port number to use (default port value is 3471).

CautionAfter configuring the Wyse VDA server software, be sure to restart the Wyse VDA service by using the Services applet (right-click the Wyse VDA service and select Restart).

Configuring the Server Communication Port NumberYou can configure the server communication port number to use (Wyse VDA client and server software communicate using this port number). The default value is 3471.

The port configuration information for Wyse VDA server software is stored at this registry location:

Key: [HKLM\Software\Wyse\VDA\Settings]

UDP Port: REG_SZ

5 Using Wyse VDA with ThinOS

This chapter contains information on using Wyse VDA with Wyse thin clients running Wyse ThinOS.

Enabling and Disabling the Wyse VDA Client Proxy Function for Thin Clients Running ThinOS

After installation, the Wyse VDA client proxy is disabled by default until you enable the service. You can enable and disable the Wyse VDA client proxy function remotely (using INI files) or locally on the thin client (using a check box). Once the Wyse VDA client proxy is in-use for a session, it cannot be disabled without terminating the session.

Enabling and Disabling the Wyse VDA Client Proxy Function RemotelyTo enable or disable the Wyse VDA client proxy function remotely, use the WyseVDA parameter in the INI files.

For example, in an ICA connection:• To enable Wyse VDA use: connection=ICA WyseVDA=yes • To disable Wyse VDA use: connection=ICA WyseVDA=no

For example, in an RDP connection:• To enable Wyse VDA use: connection=RDP WyseVDA=yes • To disable Wyse VDA use: connection=RDP WyseVDA=no

For detailed information on using the ThinOS INI files, refer to the Reference Guide: Wyse ThinOSTM INI Files.
