When you select an existing desktop pool, the Edit, Duplicate and Delete tabs become available for selection.
Table 2 highlights the options available for Desktop Pools.
Table 2: Desktop Pools
1.1.1 Add Pool
When you click on the Add tab, there are three (3) options on the type of desktop pool you wish to create; Automated Desktop Pool, Manual Desktop Pool or RDS Desktop Pool. The following sections will describe the options available within each selection.
1.1.1.1 Automated Desktop Pool
Select Automated Desktop Pool.
Select the type of virtual desktop you wish to deploy.
NOTE: As the banner states, View Composer Linked Clones are being deprecated in future releases. This guide will not cover View Composer desktop pools.
If you have multiple vCenter Servers, select this from the list.
Select either a Floating assignment or a Dedicated assignment.
When you select Dedicated, you have the option to choose whether to assign the desktop automatically to a user or allow multiple users to log onto the virtual desktop.
Depending on the storage you are using, select the relevant option.
In the ID field, enter a unique name for the pool (no spaces are allowed).
The Display Name is what the user will see once they've authenticated with the Connection Server. If no name is entered, the ID of the pool is used.
If separate administration for the pool is required, select this from the drop-down list against Access Group.
Optionally, enter a description for the pool.
Basic
Enable Provisioning – when you finish creating the pool, the virtual machines are created automatically. If you uncheck this option, the pool is created, but no virtual machines are deployed.
Stop Provisioning on Error – if an error occurs during the desktop pool creation, provisioning is stopped.
Virtual Machine Naming
Naming Pattern – specify a naming pattern for the virtual desktops for this pool. The same name is also used to join the virtual desktops to Active Directory.
Provision Machines
The options under Provision Machines allows you to create Machines on Demand by specifying the Min Number of Machines required or select All Machines Up-Front to have all the virtual desktops created once the pool creation is completed.
Desktop Pool Sizing
Specify the Maximum Machines required for this pool; if you previously selected All Machines Up-Front, this is the number of virtual desktops created.
Alternatively, if you had selected Machines on Demand, enter the number of Spare (Powered On) Machines required in the pool.
Virtual Device
Add vTPM Device to VMs provides additional security capabilities to Windows 10 and Windows Server 2016 virtual machines.

Table 12: Machines - RDS Hosts - Options
1.4.3 Others
The Others tab shows desktops that are not managed by vCenter Server, but have the Horizon agent installed on them. The information displayed for this type of machine are shown in Table 13 below.
Table 13: Machines - Others
There is only a single option for Others, as described in the table below.

1.5 Persistent Disks
The last option in this section is Persistent Disks.
This option is depreciated in Horizon 8 2006 and subsequently will be totally removed in future releases.
As this post only focuses on Full Clones and Instant Clones virtual desktops, the Persistent Disks feature is only supported with Linked Clone virtual desktops, therefore will not be covered in this post.
This concludes this bite-sized segment on the Horizon Console that focused on the Inventory section. In the next blog, I will be focusing on the Settings section, which will be the final segment of the Intermediate level.
