Overview to Scalability in CAM
Figure A-1 displays an example of CAM cluster scalability architecture. Please ensure that you can add additional compute resources as needed to accommodate increased query or data loads. The typical scalability architecture includes a cluster of Data Mediation nodes and a Data Warehouse node. During the installation of Data Mediation node, you can set up same IP address for Data Warehouse. Movers are used to propagate the intermediate results from Data Mediation into Data Warehouse. On Data Warehouse node, post-processing will consolidate the sessionization and aggregation results and update dimension tables and fact tables.
Note that associated WLCs and ISGs need to be configured to send SNMP and RADIUS records into the same Data Mediation node. For example, each Data Mediation serves a separate geographical region of WLCs and ISGs. In such case, SNMP traps from WLC and RADIUS from ISG for same user session can be associated appropriately.
