RDSH groups
When you publish resources in Parallels RAS, you need to specify one or more hosts that host them. RDSH host pools allow you to combine multiple RD Session Hosts and then publish the resources from the host pool instead of specifying individual hosts.
The main benefits of using RD Session Host host pools are as follows:
They simplify the management of published resources and are highly recommended in multi-host environments.
They allow you to use RD Session Hosts created from a template by utilizing the VDI infrastructure. More on this later in this section.
Note that an RD Session Host can be a member of one host pool only. You cannot add the same host to multiple host pools.
Creating a host pool
To create an RDSH host pool:
Navigate to Infrastructure > RD Session Hosts > Host pools.
Choose New host pool from the ellipsis menu (or click the plus-sign icon).
Type a host pool name and press Enter.
Click the new host pool name in the list to open the host pool editing screen.
Click Properties in the middle pane and configure the host pool. Settings here are similar to settings of an individual RD Session Host. See Configure an RD Session Host.
Using host pool defaults
RD Sessions Hosts assigned to a host pool have various settings that they can inherit from the host pool defaults. This makes it simpler to configure a single set of settings for all hosts instead of configuring each host individually. A Site also has its own default settings (Site defaults). Moreover, an RD Session Host host pool can inherit these Site defaults. This gives you the following choices when inheriting default settings by an RD Session Host:
Configure Site defaults and make the host pool inherit these settings. The RD Session Hosts assigned to the host pool will therefore also inherit Site defaults. This is the default scenario for a new host pool.
Configure default settings for a given host pool. This way you can have multiple host pools, each having its own host pool defaults (different from Site defaults). Therefore, the hosts assigned to a host pool will inherit the host pool defaults.
