HP RGS Protocol

RGS is a display protocol from HP that allows users to access the desktop of a remote physical computer over

a standard network.

You can use HP RGS as the display protocol when connecting HP Blade PCs, HP Workstations, and HP Blade

Workstations. Connections to virtual machines that run on VMware ESX servers are not supported.

HP RGS provides the following features:

You can use multiple monitors in span mode.

You can configure the amount of bandwidth used by Adobe Flash content to improve the overall Web

browsing experience and make other applications more responsive.

VMware does not bundle or license HP RGS with VMware View. Contact HP to license a copy of HP RGS

version 5.2.5 to use with VMware View. For information about how to install and configure HP RGS

components, see the HP RGS documentation available at http://www.hp.com.

Using a View Desktop Without a Network Connection

With View Client with Local Mode, users can check out and download a View desktop to a local system such

as a laptop. Administrators can manage these local View desktops by setting policies for the frequency of

backups and contact with the server, for access to USB devices, and for permission to check in desktops.

For employees at remote offices with poor network connections, applications run faster on a local View desktop

than on a remote desktop. Also, users can use the local version of the desktop with or without a network

connection.

If a network connection is present on the client system, the desktop that is checked out continues to

communicate with View Connection Server to provide policy updates, and ensure that locally cached

authentication criteria is current. By default, contact is attempted every 5 minutes.

View Client with Local Mode is the fully supported feature that in earlier releases was an experimental feature

called View Client with Offline Desktop.

View desktops in local mode behave in the same way as their remote desktop equivalents, yet can take

advantage of local resources. Latency is eliminated, and performance is enhanced. Users can disconnect from

their local View desktop and log in again without connecting to the View Connection Server. After network

access is restored, or when the user is ready, the checked-out virtual machine can be backed up, rolled back,

or checked in.

Local resource

utilization

After a local desktop is checked out, it can take advantage of the memory and

CPU capabilities of the local system. For example, memory available beyond

what is required for the host and guest operating systems is usually split

between the host and the local View desktop, regardless of the memory settings

that are specified for the virtual machine in vCenter Server. Similarly, the local

View desktop can automatically use up to two CPUs available on the local

system, and you can configure the local desktop to use up to four CPUs.
