8 3.3 Virtual desktop OS license and activation When performing a full desktop virtualization (VDI desktops) deployment, the Quick Start Tool will prompt you for the Microsoft Windows desktop operating system installation media and product key. You must use a volume license key and Pro/Enterprise version of Windows 7 SP1, Windows 8.1, or Windows 10. An OEM license cannot be used for the desktops. The desktop operating system must be activated on each virtual desktop that is deployed. Microsoft allows for activating volume license products via Key Management Service (KMS), Multiple Activation Key (MAK), and Active Directory-based Activation (for newer products only). Dell recommends using KMS or Active Directory-based Activation (if applicable for your environment). When using one of these volume activation models, specify a Generic Volume License Key (GVLK) for your desktop OS product key. The GVLKs are also referred to as KMS Client Setup Keys and are posted online by Microsoft. Setting up volume activation is beyond the scope of this document. NOTE: The Quick Start Tool only supports the installation of Windows 7 SP1, Windows 8.1, or Windows 10 for the desktop template at this time. To create templates using a different desktop OS, allow the tool to complete the deployment using one of the supported operating systems and then refer to the Virtualization software documentation for information on manually creating a template VM with the OS of your choice. 3.4 Activating RDS license server and CALs This section only applies when deploying application virtualization or shared session desktops. In this configuration, the broker management VM is configured as the RDS license server and the Remote Desktop Session Host (RDSH) VMs are associated with this server for client access licensing purposes. The license server must be activated and the appropriate number of RD client access licenses (CALs) must be installed. If your Microsoft volume license agreement does not allow for the necessary RD CALs, they must be purchased with your appliance. To activate the RDS license server and install the RD CALs, perform the following tasks: 1. Log in to your broker management VM (created during deployment). Refer to the Default Names and Credentials section in this document for the default name of the broker management VM. 2. Launch Server Manager and click Tools > Terminal Services > Remote Desktop Licensing Manager. 3. Right-click the broker management VM name and select Activate Server. 4. Click Next on the welcome screen. 5. Ensure the connection method is set to Automatic and click Next. 6. Fill in the requested company information and click Next. 7.

11 4.2 Cabling your appliance By default, appliances are sold with network cards that contain two 10Gb ports + two 1Gb ports. The two 10Gb ports should be connected, teamed, and used for your virtualization environment. Figure 3 Dell PowerEdge R730 network cabling The blue lines (connections) represent the production network ports used by the appliance and virtual machines (VMs). The orange line (connection) represents the idrac connection for remote management of your system. NOTE: At least one of the 10Gb network ports must be connected for the appliance to function. Dell recommends that you connect both 10Gb network ports to achieve the best performance. If you ve ordered additional 10Gb network cards, they can be added to a single team. 4.3 First boot experience After the prerequisites are fulfilled and your appliance is correctly cabled, turn on the appliance to perform the first boot tasks: 1. Select the necessary language for the Windows OS and then specify your country, application language, and keyboard layout. 2. Accept the Microsoft EULA for the Windows OS. 3. Enter a password for the local administrator account. 4. Log in to the appliance by using the local administrator account and click OK after reading the notification message. 4.4 Creating a network team and virtual switch An external Hyper-V virtual switch much be created for the appliance to function properly. The recommended network connection for the switch is a NIC team.

If they are not configured, the QST will automatically attempt to create them. If manually creating, the recommended settings are listed below. 11 No Restrictions Dell Appliance for Wyse Citrix 07/2016

12 Network team settings: Name: NetworkTeam Member adapters: 10Gbps ports Teaming mode: Switch independent Load balancing mode: Dynamic Standby adapter: None (all adapters Active) Hyper-V virtual switch settings: External network connection type using previously created/selected network team Management OS sharing network adapter Name must be set as vswitch in order for the QST to detect it NOTE: The QST will automatically attempt to create these components if none are detected. 4.5 Joining appliance to Active Directory Your appliance must be a member of an Active Directory domain to function correctly and for deployment to complete successfully. Before proceeding with deployment and configuration, make your appliance a member of your Active Directory domain by modifying the server System Properties. NOTE: The Quick Start Tool for your appliance uses Windows PowerShell and makes system changes which can both be impacted by Group Policy Settings. Dell highly recommends temporarily preventing group policies from being applied to the appliance while the Quick Start Tool is performing the deployment. To prevent group policies from being applied during deployment, move the appliance computer account to an Organizational Unit in AD that has group policy inheritance blocked or by security filters on individual Group Policy Objects. To avoid policies from applying to the virtual machines that will be created during deployment, create computer accounts in the same OU before launching the Quick Start Tool refer to the Default Names and Credentials section for the computer names that will be used. This is accomplished by right-clicking the OU and selecting New Computer. After deployment, the Group Policy restrictions can be removed. WARNING: Not following these tasks typically results in a failed deployment; therefore, the Quick Start Tool requires that the user acknowledges that the steps have been performed. 12 No Restrictions Dell Appliance for Wyse Citrix 07/2016
