AD Connector Sizing Guidelines
For Active Directory integration with Virtual Appliances, we recommend that you size the AD Connector deployment for the number of VAs and domain controllers configured to communicate with this connector.
| Number of Virtual Appliances | Number of Domain Controllers | Minimum Connector Specifications |
|---|---|---|
| 1-2 | 1-5 | 2 CPU, 1 GB RAM |
| 4-15 | 6-20 | 4 CPU, 8 GB RAM |
| 16-20 | 21-64 | 4 CPU, 16 GB RAM |
| >20 | >64 | 8 CPU, 32 GB RAM |
Each domain controller is assumed to process a maximum of 400 AD events a second. If any of your domain controllers are processing more events, make sure to increment the number of domain controllers accordingly. For example, if you have a domain controller that processes around 1000 AD events a second at peak load, count that as three domain controllers in the sizing table above.
If a connector is run on a system with lower CPU and memory specifications, the connector will continue to function. Some optimizations, such as parallel synchronization of login events to virtual appliances, will not be turned on.
