2.4 Distributed System Configurations
Given all the variants that could exist in distributed system configurations, it is
impossible to test and give precise limits for all the possible scenarios. Tests have
been performed for some given scenarios run with a constant load of 5 alarms per
second. Based on them, conclusions and comments are presented here below:
Hierarchical
Number of supervised systems
30
Total amount of system objects
1,500,000
Per supervisor system
Per supervised system
Maximum number of remote
installed clients
2
10
Maximum number of remote
windows app and web clients
20
30
Maximum number of Flex clients
40
40
In hierarchical configurations, the supervisor server should not contain any kind of
integration (either local, or via FEP). This statement becomes more important the
bigger the amount of system objects in the supervisor is. The limits indicated in the
table above have been tested with no subsystems or FEPs connected to the
supervisor.
