View Connection Server Cluster Design Considerations
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.
IMPORTANT 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.
Maximum Connections for View Connection Server
Table 4-8 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.
Table 4-8. View Desktop Connections
Connection Servers per Deployment Connection Type
Maximum Simultaneous
Connections
1 Connection Server Direct connection, RDP or PCoIP;
Tunneled connection, RDP;
PCoIP Secure Gateway connection
2,000
7 Connection Servers (5 + 2 spares) Direct connection, RDP or PCoIP 10,000
1 Connection Server Unified Access to physical PCs 100
1 Connection Server Unified Access to terminal servers 200
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.
View Transfer Server Virtual Machine Configuration and Storage
View Transfer Server is required to support desktops that run View Client with Local Mode (formerly called
Offline Desktop). This server requires less memory than View Connection Server.
View Transfer Server Configuration
You must install View Transfer Server on a virtual rather than a physical machine and the virtual machine
must be managed by the same vCenter Server instance as the local desktops that it will manage. Table 4-9 lists
the virtual machine specifications for a View Transfer Server instance.
