Your FortiGate unit has a limited amount of hardware resources such as memory, disk storage, CPU operations. When Virtual Domains are disabled, this limit is not a major concern because all sessions, users, and other processes share all the resources equally.

When using Virtual Domains, hardware resources can be divided differently between Virtual Domains as they are needed. Minimum levels of resources can be specified for each VDOM, so that no Virtual Domain will suffer a complete lack of resources.

For example, if one VDOM has only a web server and logging server connected, and a second VDOM has an internal network of 20 users, these two VDOMs will require different levels of resources. The first VDOM will require many sessions but no user accounts. This compares to the second VDOM where user accounts and management resources are required, but fewer sessions.

Using the global and per-VDOM resource settings, you can customize the resources allocated to each VDOM to ensure the proper level of service is maintained on each VDOM.
