Linked-Clone Desktop Data Disks
View Composer creates more than one data disk to store the components of a linked-clone desktop.
OS Disk
View
Composer creates an OS disk for each linked clone. This disk stores the system data that the clone needs
to remain linked to the base image and to function as a unique desktop.
QuickPrep Configuration-Data Disk
View Composer creates a second disk with the OS disk. The second disk stores QuickPrep configuration data
and other OS-related data that must be preserved during refresh and recompose operations. This disk is small,
typically about 20MB. This disk is created whether you use QuickPrep or Sysprep to customize the desktop.
If you configure separate View Composer persistent disks to store user profiles, three disks are associated with
each linked clone: the OS disk, the second desktop disk, and the View Composer persistent disk.
The second desktop disk is stored on the same datastore as the OS disk. You cannot configure this disk.
View Composer Persistent Disk
In a dedicated-assignment pool, you can configure separate View Composer persistent disks to store Windows
user-profile data. This disk is optional.
Separate persistent disks let you preserve user data and settings. View Composer refresh, recompose, and
rebalance operations do not affect persistent disks. You can detach a persistent disk from a linked clone and
attach it to another linked clone.
If you do not configure separate persistent disks, the Windows profile is stored in the OS disk. User data and
settings are removed during refresh, recompose, and rebalance operations.
You can store persistent disks on the same datastore as the OS disk or on a different datastore.
Disposable-Data Disk
When you create a linked-clone pool, you can configure a separate, nonpersistent disk to store the guest OS's
paging and temp files that are generated during user sessions. You must specify the disk size in megabytes.
This disk is optional.
When the linked clone is powered off, View Manager replaces the disposable-data disk with a copy of the
original disk that View Composer created with the linked-clone pool. Linked clones can increase in size as
users interact with their desktops. Using disposable-data disks can save storage space by slowing the growth
of linked clones.
The disposable-data disk is stored on the same datastore as the OS disk.
Manual Desktop Pools
To create a manual desktop pool, View Manager provisions desktops from existing desktop sources. You select
a separate desktop source for each desktop in the pool.
View Manager can use several types of desktop sources in manual pools:
n
Virtual machines that are managed by vCenter Server
n
Virtual machines that run on VMware Server or another virtualization platform
n
Physical computers
n
HP Blade PCs
