Configuring resources
Before you start the FortiGate-VM for the first time, configure the following resources as the FortiGate-VM license specifies:
- Disk sizes
- CPUs
- RAM: FortiOS does not have licensed RAM size restrictions. Having at least 4 GB of RAM for proper FortiGate-VM operation is recommended, especially if unified threat management, zero trust network access, or proxy is enabled.
- Network settings
To configure the resources for a FortiGate-VM deployed on OpenStack, use the OpenStack Horizon client.
You can apply a smaller FortiGate-VM license if you are OK with consuming less CPU than is present on your instance. See FortiGate-VM virtual licenses and resources.
