Administration

Procedure
1 On the View Composer Domains page, click Add to add the View Composer user for AD
operations account information.
2 Type the domain name of the Active Directory domain.
For example: domain.com
3 Type the domain user name, including the domain name, of the View Composer user.
For example: domain.com\admin
4 Type the account password.
5 Click OK.
6 To add domain user accounts with privileges in other Active Directory domains in which you
deploy linked-clone pools, repeat the preceding steps.
7 Click Next to display the Storage Settings page.
What to do next
Enable virtual machine disk space reclamation and configure View Storage Accelerator for Horizon
7.
Allow vSphere to Reclaim Disk Space in Linked-Clone Virtual
Machines
In vSphere 5.1 and later, you can enable the disk space reclamation feature for Horizon 7. Starting
in vSphere 5.1, Horizon 7 creates linked-clone virtual machines in an efficient disk format that
allows ESXi hosts to reclaim unused disk space in the linked clones, reducing the total storage
space required for linked clones.
As users interact with linked-clone desktops, the clones' OS disks grow and can eventually use
almost as much disk space as full-clone desktops. Disk space reclamation reduces the size of the
OS disks without requiring you to refresh or recompose the linked clones. Space can be reclaimed
while the virtual machines are powered on and users are interacting with their remote desktops.
Disk space reclamation is especially useful for deployments that cannot take advantage of storage-
saving strategies such as refresh on logoff. For example, knowledge workers who install user
applications on dedicated remote desktops might lose their personal applications if the remote
desktops were refreshed or recomposed. With disk space reclamation, Horizon 7 can maintain
linked clones at close to the reduced size they start out with when they are first provisioned.
This feature has two components: space-efficient disk format and space reclamation operations.
In a vSphere 5.1 or later environment, when a parent virtual machine is virtual hardware version
9 or later, Horizon 7 creates linked clones with space-efficient OS disks, whether or not space
reclamation operations are enabled.
