VCP5-DT Objective 2.6–Configure Advanced Display Protocol Settings (PCoIP/RDP)

Objective 2.6 – Configure Advanced Display Protocol Setting (PCoIP/RDP)

For this objective I used the following resources:

  • VMware View Administration guide
  • VMware View Installation guide

Knowledge

Reference GPO Templates

The GPO Templates that come with view are discussed in Objective 1.5 Prepare Active Directory for Installation located HERE. Section titled “Identify and Describe GPO Template Files”.

Describe RDP Requirements

  • Windows XP and Windows XP Embedded systems, you should use Microsoft RDC 6.x
  • Windows Vista comes with RDC 6.x installed, though RDC 7 is recommended
  • Windows 7 comes with RDC 7 installed. Windows 7 SP1 comes with RDC 7.1 installed
  • You must have RDC 6.0 or later to use multiple monitors
  • Windows XP virtual machines must have the RDP patches listed in Microsoft KB article 323497 & 884020 installed
  • The View Agent installer configures the local firewall rule for inbound RDP connections to match the current RDP port

See page 18 of the VMware View Installation guide for additional information

Locate ADM Template Files

Comes with six ADM Template files that you can leverage in your environment (see Objective 1.5 for a full listing). These ADM Templates are located on View Connection servers in the install_directory\VMware\VMware View\Server\extras\GroupPolicyFiles:

Explain GPO Settings

  • Describe “build to lossless”

The PCoIP display protocol uses an encoding approach called progressive build, which works to provide the optimal overall user experience even under constrained network conditions. Progressive build provides a highly compressed initial image, called a lossy image, that is then progressively built to a full lossless state. A lossless state means that the image appears with the full fidelity intended.

The build-to-lossless feature provides the following characteristics:

  • Dynamically adjusts image quality
  • Reduces image quality on congested networks
  • Maintains responsiveness by reducing screen update latency
  • Resumes maximum image quality when the network is no longer congested

See pages 166 thru 167 of the VMware View Administration guide for additional information

  • Describe how to configure cache size

This setting is configured in the View PCoIP Session Variable ADM template (pcoip.adm):

As described on page 158 of the VMware View Administration guide:

Configure PCoIP client image cache size policy – Controls the size of the PCoIP client image cache. The client uses image caching to store portions of the display that were previously transmitted. Image caching reduces the amount of data that is retransmitted. This setting applies only to Windows and Linux clients when View Client, View Agent, and View Connection Server are a View 5.0 or later release. When this setting is not configured or disabled, PCoIP uses a default client image cache size of 250MB. When you enable this setting, you can configure a client image cache size from a minimum of 50MB to a maximum of 300MB. The default value is 250MB.

Identify maximum number of monitors and resolution

  • The use of multiple monitors is supported. VMware View supports up to four monitors and with a maximum resolution per monitor of 2560 x 1600.
  • If utilizing Windows 7 3D Rendering View supports a maximum of two monitors and the resolution is set to 1920 x 1200 (This value cannot be changed).

Configure Flash quality and throttling

These options can be configured during the desktop pool creation process or modified after creation:

The Adobe Flash quality option has for settings:

  • Do not control – Quality is determined by Web page settings
  • Low – This setting results in the most bandwidth savings. If no quality level is specified, the system defaults to Low
  • Medium – This setting results in moderate bandwidth saings
  • High – This setting results in the least bandwidth savings

The Adobe Flash throttling option has for settings:

  • Disabled – No throttling is performed. The timer interval is not modified
  • Conservative – Timer interval is 100 milliseconds. This setting results in the lowest number of dropped frames
  • Moderate – Timer interval is 500 milliseconds
  • Aggressive – Timer interval is 2500 milliseconds. This setting results in the highest number of dropped frames

Configure software 3D rendering capabilities

This option can be configured during the desktop pool creation process or modified after creation:

pic3

To enable 3D graphics the desktop pool must bee the following requirements:

  • The desktops must run on ESXi 5.0 or later hosts and be managed by vCenter Server 5.0 or later
  • The desktops must be Windows 7 or later
  • The desktops must have virtual hardware v8 or later
  • The pool must use the PCoIP as the default display protocol
  • User must not be allowed to choose their own protocol
