SNS EVA firewalls scale their capacities (maximum number of connections, rules, objects, VPN tunnels, etc.) according to the resources allocated to the hypervisor. Note:
- An EVA must have at least 1 GB of memory. You are advised to set aside at least 2 GB of memory if you use the antivirus and sandboxing features frequently.
- An EVA1 machine with 2 GB of RAM and an EVA2 machine with 2 GB of RAM have the same capacities - only the number of vCPU allowed differs.
-
It is possible to easily switch from one EVA model to another, within the limits of the license purchased, by changing the RAM and vCPU characteristics of the virtual machine, then restarting it.
IMPORTANT
Before lowering the memory of a virtual machine, ensure beforehand that the new limits applied will be compatible with the existing configuration.
