Setting Up Desktop and Application Pools in View

Table 11‑4. Desktop Pool Setting Descriptions (Continued)
Setting Options
Refresh OS disk
after logoff
Select whether and when to refresh the OS disks for dedicated-assignment, linked-clone virtual
machines.
n
Never. The OS disk is never refreshed.
n
Always. The OS disk is refreshed every time the user logs off.
n
Every. The OS disk is refreshed at regular intervals of a specified number of days. Type the
number of days.
The number of days is counted from the last refresh, or from the initial provisioning if no
refresh has occurred yet. For example, if the specified value is 3 days, and three days have
passed since the last refresh, the machine is refreshed after the user logs off.
n
At. The OS disk is refreshed when its current size reaches a specified percentage of its
maximum allowable size. The maximum size of a linked clone's OS disk is the size of the
replica's OS disk. Type the percentage at which refresh operations occur.
With the At option, the size of the linked clone's OS disk in the datastore is compared to its
maximum allowable size. This disk-utilization percentage does not reflect disk usage that you
might see inside the machine's guest operating system.
When you refresh the OS disks in a linked-clone pool with dedicated assignment, the View
Composer persistent disks are not affected.
Default display
protocol
Select the display protocol that you want View Connection Server to use to communicate with
clients.
PCoIP
The default option wherever it is supported. PCoIP is supported as
the display protocol for virtual and physical machines that have
Teradici hardware. PCoIP provides an optimized PC experience for
the delivery of images, audio, and video content for a wide range of
users on the LAN or across the WAN.
Microsoft RDP
Microsoft Remote Desktop Connection (RDC) uses RDP to transmit
data. RDP is a multichannel protocol that allows a user to connect to
a computer remotely.
Allow users to
choose protocol
Allow users to override the default display protocol for their desktops by using Horizon Client.
3D Renderer You can select whether to enable 3D graphics rendering if your pool comprises Windows 7 or
later desktops. You can configure the 3D Renderer to use software rendering or hardware
rendering based on physical GPU graphics cards installed on ESXi 5.1 or later hosts.
To enable this feature, you must select PCoIP as the protocol and disable the Allow users to
choose protocol setting (select No).
With the hardware-based 3D Renderer options, users can take advantage of graphics applications
for design, modeling, and multimedia. With the software 3D Renderer option, users can take
advantage of graphics enhancements in less demanding applications such as AERO, Microsoft
Office, and Google Earth. For system requirements, see “Configuring 3D Rendering for
Desktops,” on page 126.
If your View deployment does not run on vSphere 5.0 or later, this setting is not available and is
inactive in View Administrator.
When you select this feature, you can configure the amount of VRAM that is assigned to machines
in the pool. You can select at most two monitors for your machines that are used as remote
desktops. The Maximum resolution of any one monitor is set to 1920x1200 pixels. You cannot
configure this value.
NOTE When you configure or edit this setting, you must power off existing virtual machines,
verify that the machines are reconfigured in vCenter Server, and power on the machines to cause
the new setting to take effect. Restarting a virtual machine does not cause the new setting to take
effect.
For more information, see “Configuring 3D Rendering for Desktops,” on page 126, “3D Renderer
Options,” on page 128. and “Best Practices for Configuring 3D Rendering,” on page 130.
