The total configuration file size of Panorama™ M-Series and virtual appliances is an important piece of the performance metric when determining which M-Series appliance or the minimum amount of virtual resources you need to allocate on your Panorama virtual appliance to ensure that you meet your Security requirements. Exceeding the supported total configuration file size of the Panorama management server results in reduced performance when performing configuration changes, commits, and pushes to managed firewalls.

Starting with PAN-OS 11.1, both Panorama and managed firewalls proactively monitor configuration size and alerts administrators when it nears or exceeds the recommended threshold. The lower-end platforms with smaller configuration limits, might hit the warning during the config push from Panorama.

The Panorama management server in Panorama mode supports a total configuration file size of 80MB for all template, device group, and Panorama-specific configurations. The maximum configuration file size supported by Panorama in Management Only mode depends on the Panorama model or resources you allocate to the Panorama virtual appliance. Refer to the table below for the recommended maximum configuration file size based on the Panorama M-Series appliance model or on the resources you allocate to the Panorama virtual appliance.
