Controller sizing
Comments
-
A controller can scale to 5k CPE/branches assuming the following hardware resources-
*16 core Intel Xeon Skylake16 CPU
*16GB RAM
*120 GB SSD
*4 x 1/10 Gigabit Ethernet NIC
This number is based on 5k IKE based IPsec tunnels and 5k MP-BGP sessions. (1 each per CPE)

Hi jovo,
Please, also important note about controllers and hub-controllers deployment, mentioned in Hardware and Software Requirements for Headend - Versa Networks:
- When more than 500 sites are connected to a Controller or Hub-Controller node, allocate eight CPUs for control plane processing by issuing the following CLI command and then rebooting the node:
Controller-CLI> request system isolate-cpu enable num-control-cpu 8
Note: The above assumes the system has a minimum of 16 cores out of which 8 cores are reserved for the control plane.
