The following tables in the FortiNAC Data Sheet are guidelines to determine the most appropriate FortiNAC server for a customer's environment:
Hardware Server Sizing
VM Server Resource Sizing
The criteria used is the total number of ports in the network. If an environment grows beyond the max number of ports specified for a particular server, performance issues can occur due to CPU and memory allocation. In such cases, the FortiNAC system resources should be re-evaluated.
Administrators can utilize tools within the FortiNAC UI to monitor performance. See Monitoring for more details.
Certain performance-related parameters are modifiable. See Tuning for more details.
