Desktop Info Servers
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:
• Using a Desktop Info Server Architecture, page 6-1
• Installing a Dual Server Desktop Architecture, page 6-2
Using a Desktop Info Server Architecture
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
Note If you implement a DSD architecture, you cannot configure Info Server failover using the failover
feature.
