Appendix B: Maximum configuration values
These tables show the maximum number of configuration objects or limits that vary by them, and are not a guarantee of performance. For values such as hardware specifications that do not vary by software version or configuration, see your model’s QuickStart Guide.

The below values are per ADOM. For example, the maximum number of server policies is 256 on a FortiWeb 4000D. Each additional ADOM can have an additional 256 server policies.
However, due to the performance impact relative to each model's RAM constraints, maximizing the number of objects in all ADOMs is obviously not recommended..

Maximum values on FortiWeb-VM
FortiWeb-VM has 4 virtual network interfaces (vNICs, or virtual ports).
The maximum number of server policies initially varies by the maximum amount of virtual memory (vRAM) available to FortiWeb-VM in VMware, up to a hard limit. FortiWeb-VM will allow up to 20 policies for the first 1 GB of vRAM, then an additional 15 policies per additional 1 GB of vRAM, up to a maximum of 255 server policies.
In other words, at first, the server policy limit increases linearly with vRAM. But after 7 GB of vRAM, further increasing the vRAM no longer has an affect. 8 GB or more vRAM allows up to
255 server policies. (Keep in mind that increasing the vRAM may still benefit performance.)
The maximum number of sessions with the back-end web servers varies by the maximum number of vCPUs allowed by your FortiWeb-VM license.
To see the maximum allowed sessions for your FortiWeb-VM installation
1. Go to Policy > Server Policy > Server Policy.
2. Either click New or edit an existing policy.
3. Look at the minimum-maximum range indicator next to the Persistent Server Sessions option. That number tells you the maximum server sessions for your installation.
