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.
- The switch from one EVA model to another is facilitated by using a generic serial number "VMSNS" that is not dependent on the model. However, before lowering the memory of a virtual machine, ensure beforehand that the new limits applied will be compatible with the existing configuration.
