When you install View Connection Server, the View Administrator user interface is also installed.

Although you can install View Connection Server on a physical machine, this example uses a virtual machine with the specifications listed in Connection Server Virtual Machine Example. The ESXi host for this virtual machine can be part of a VMware HA cluster to guard against physical server failures.

Connection Server Virtual Machine Example



Operating system

64-bit Windows Server 2008 R2



Virtual CPU


System disk capacity


Virtual SCSI adapter type

LSI Logic SAS (the default for Windows Server 2008)

Virtual network adapter



1 Gigabit

You can deploy multiple replicated View Connection Server instances in a group to support load balancing and high availability. Groups of replicated instances are designed to support clustering within a LAN-connected single-datacenter environment.


VMware does not recommend or support using a group of replicated View Connection Server instances across a WAN, MAN (metropolitan area network), or other non-LAN due to the communication traffic needed between the grouped instances. In scenarios where a View deployment needs to span datacenters, create a separate Horizon View deployment for each datacenter.

View Desktop Connections provides information about the tested limits regarding the number of simultaneous connections that a Horizon View deployment can accommodate.

This example assumes that you are using Horizon View with vSphere 4.1 or later and vCenter Server 4.1 or later. It also assumes that View Connection Server is running on a 64-bit Windows Server 2008 R2 Enterprise operating system.

PCoIP Secure Gateway connections are required if you use security servers for PCoIP connections from outside the corporate network. Tunneled connections are required if you use security servers for RDP connections from outside the corporate network and for USB and multimedia redirection (MMR) acceleration with a PCoIP Secure Gateway connection. You can pair multiple security servers to a single connection server.
