RDSH & VDI Distribution to Local Storage

0 users found this article helpful

Extending the flexibility of Parallels RAS, version 18 provides customers with the ability to deploy clones from RAS templates, used as RD Session Hosts or VDIs, not only to the centrally shared storage, such as SAN, but also to local disks of multiple independent Microsoft Hyper-V hosts. A template is distributed to the local storage of specified Microsoft Hyper-V hosts so that clones may reside in the same local storage location. Scaling out is also easily carried out by adding other Microsoft Hyper-V providers to the template provider distribution list.




Supported on a standalone Microsoft Hyper-V Server 2012 R2, 2016 and 2019

All providers included in the Target list must have identical:

Note: Full clones can also be moved to other hosts via Live migration, but the process is time-consuming (similar to when first copying the template).

Configuring VDI Template Distribution to Local Storage

For this example, we will use two standalone Windows 2016 Hyper-V Servers: H01.RASLAB.lab and HV02.RASLAB.lab. We will create a virtual machine named W10Master in HVM01 and automatically replicate it to HVM02 using the template distribution functionality provided by Parallels RAS.

Note: If authentication isn't working, try changing the Use any authentication protocol option.


VDI Template Distribution

Templates are used to automate the creation and deployment of guest VMs in Parallels RAS. To enable and configure VDI template distribution, follow the steps shown below:

  1. Open the Parallels RAS Console
  2. Locate the Templates tab in the VDI section.
  3. Click on the Add option from the Tasks drop-down menu and select a machine from the Virtual Guests List.
  4. Complete the Type, Check Agent, General and Additional pages of the wizard according to your needs.  
  5. The template distribution settings are configured on the Distribution page.

  1. Continue with the Advanced, Preparation , Optimization, License Keys and Summary pages of the wizard.
  2. Click on the Finish button.
Note: The Enable multi-provider template distribution setting cannot be modified (selected or cleared) once the template is created. If later you decide to turn it on or off (enable or disable the feature), you will need to delete and re-recreate the entire template. You can, however, add or remove VDI providers to/from an existing template.

Once you have finished the Create Parallels Template Wizard, the template distribution status can be monitored in the Templates tab.

The template replication status is displayed within the Distribution column and may contain the following values:

Note that you can also add or remove a VDI provider to/from a distribution list at any time using the Template Properties dialog. To open the dialog, right-click on a template from the VDI > Templates tab , choose Properties and then select the Distribution tab.
