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 To use a group of replicated View Connection Server instances across a WAN, MAN
(metropolitan area network), or other non-LAN, in scenarios where a View deployment needs to span
datacenters, you must use the Cloud Pod Architecture feature. You can link together 25 View pods to
provide a single large desktop brokering and management environment for five geographically distant sites
and provide desktops and applications for up to 50,000 sessions. For more information, see Administering
View Cloud Pod Architecture.
Maximum Connections for View Connection Server
Table 4-7 provides information about the tested limits regarding the number of simultaneous connections
that a View deployment can accommodate.
This example 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 or Access Point appliances for
PCoIP connections from outside the corporate network. Blast Secure Gateway connections are required if
you use security servers or Access Point appliances for Blast Extreme or HTML Access connections from
outside the corporate network. Tunneled connections are required if you use security servers or Access
Point appliances for RDP connections from outside the corporate network and for USB and multimedia
redirection (MMR) acceleration with a PCoIP or Blast Secure Gateway connection. You can pair multiple
security servers to a single View Connection Server instance.
Although the maximum number of simultaneous connections to security servers is also 2,000, instead of
using just one security server per View Connection Server instance (with 2,000 sessions), you might choose
to use 2 or 4. Monitoring of the security server might indicate that the activity for 2,000 users is too great.
The required amount of memory and CPU usage might dictate that you add more security servers per View
Connection Server instance to spread the load. For example, you might use 2 security servers, with each one
handling 1,000 connections, or you might use 4 security servers, with each one handling 500 connections.
The ratio of security servers to View Connection Server instances depends on the requirements of the
particular environment.
