How to calculated the number of connectivity services in relation to the number of controllers
How to calculated the number of connectivity services in relation to the number of controllers, for an 800xA 6.0.3 system. We are using PM864 (6) and PM866 (12) on 2 connectivity servers (1 redundant set).
But the manual is not clear about how to calculate the load on the 2 CS's with the given controllers.
The default dimensioning rule for Connectivity Server count is based on controller count. (12 controllers per separate connectivity server) This is an empirical parameter that has proven to provide predictable results for standard configurations.The controller count per Connectivity Server will typically increase with this method. The required number of controllers is distributed across the calculated amount of Connectivity Servers, considering the maximum number of controllers per Connectivity Server. If this number is exceeded, an additional server has to be used even if the data need does not require it.
How ever ,since you have 12 no of PM866 which allows larger applications it is recommended to apply the alternative dimensioning method which is the optimized rule . The calculation for the optimized rule is done using a new version of the 800xA Wizard .(While using Optimized calculation rule it may allow upto 48 controllers per connectivity server ).
