The SDN Connector serves as a gateway bridging SDN controllers and FortiGates. The SDN Connector registers itself to APIC in the Cisco ACI fabric, polls interested objects, and translates them into address objects. The translated address objects and associated endpoints populate to the FortiGate.
FortiGates register to ACI objects through the SDN Connector. The SDN Connector monitors the objects and updates FortiGate dynamic objects.
If you plan to instantiate a large number of VMs in your SDN Connector environment, ensure you size the host VM or server appropriately. The following recommendations represent the minimum sizing numbers:
- Memory: 4 GB
- CPU: 2 vCPU
- Disk: 20-50 GB
- vNICs: 1
