Before a user can check out a linked-clone desktop so that it can run in local mode, you must publish its base
image to the Transfer Server repository.
When you publish an image file to the Transfer Server repository, View Transfer Server stores the files as
encrypted packages. View Transfer Server can compress the packages to streamline downloads to local
desktops.
When a user checks out a linked-clone desktop for the first time, View Transfer Server performs two operations:
n
Downloads the base image from the Transfer Server repository to the local computer.
n
Downloads the remote linked-clone desktop from the datacenter to the local computer. The desktop
consists of the linked clone's OS delta disk and a View Composer persistent disk.
When you run linked-clone desktops in the datacenter, the linked clones share access to one base image. When
you run a linked-clone desktop in local mode, a copy of the base image must reside with the linked-clone
desktop on the local computer.
The base image is downloaded only once if it remains unchanged. When users check in and check out their
desktops again, View Transfer Server downloads the linked clones' OS delta disks and View Composer
persistent disks, not the base image.
If a base image is recomposed, View Transfer Server downloads the updated image from the Transfer Server
repository to the local computers the next time users check out their desktops. For details, see “Recompose
Linked-Clone Desktops That Can Run in Local Mode,” on page 195.
IMPORTANT A linked-clone desktop that was created from a base image must be checked into the datacenter
before you can recompose it.
Determine the Size of a View Composer Base Image
The Transfer Server repository must be large enough to store the View Composer base images for all the linked-
clone desktops that are used in local mode. To make sure that the Transfer Server repository can accommodate
a particular base image, you can determine the approximate size of the base image.
A base image can be several gigabytes in size.
The maximum size of a base image is the sum of the provisioned sizes of the hard disks in the parent virtual
machine. The actual base image size might be smaller than the maximum.
Prerequisites
Verify that you created a parent virtual machine to use for creating a linked-clone desktop pool.
Procedure
1 In vSphere Client, select the parent virtual machine.
2 Click Edit Settings.
3 In the Hardware tab, select the first configured hard disk.
For example, select Hard Disk 1.
4 In the Disk Provisioning pane, read the Provisioned Size.
5 If the virtual machine has more than one hard disk, repeat steps 3 and 4 for each additional hard disk.
6 Add the provisioned sizes of the hard disks.
