This chapter contains information about configuring a Desktop Info Server architecture, which you can 
use to reduce the load on Info Servers that receive high numbers of events.

This chapter contains the following sections:

You can use a Desktop Info Server architecture to increase the performance of an Info Server that 
frequently experiences heavy loads. For example, this can occur when many regional Info Servers send 
events to a central Info Server through unidirectional gateways and many desktops connect directly to 
the central Info Server.

When an Info Server becomes overloaded, unidirectional gateways cannot insert all events into the Info 
Server database. Additionally, desktops connected directly to the Info Server further increase the load, 
especially if a large number of desktops connect simultaneously.

The Desktop Info Server architecture:

Reduces the central Info Server's workload by shifting the load to specialized Desktop Info Servers

Improves desktop responsiveness (the time between a desktop user’s action and its reflection in the 
desktop GUI)

Reduces occurrences of desktop GUI freezing

Improves the end-to-end latency times in heavily-loaded, standard Info Server configurations

If you implement a DSD architecture, you cannot configure Info Server failover using the failover 
feature.
