FortiOS Handbook V2, Chapter 11: Virtual Domains

This guide provides detailed information about FortiGate VDOMs. It is intended for administrators who need guidance on solutions to suit different network needs and information on basic and advanced configuration of VDOMs. Virtual Domains (VDOMs) multiply the capabilities of your FortiGate unit by using virtualization to partition your resources. VDOMs enable your FortiGate unit to split its resources and function as multiple independent units with common administration.
