Generally having one Manager on the network is the way to go. This Manager will have access to all cores allowed by the license, and all connections with workers and clients can be established by auto-detection.
But in some cases you may need to have multiple managers - maybe group A must not be able to see what group B is working on and vice versa.
Setting up multiple managers
If you have a floating license you can have multiple managers. These will be sharing the number of cores allowed by your license. Follow the same setup procedure as you would normally do (see Manager Setup) and refer to the same license server on all managers.
The key difference from one manager setups is, that you can not use Auto-Detect in the connection settings. You must set a fixed host in the connection settings for both workers and clients.
If you want to limit who can send jobs to the different managers, you can enable the User system on each manager (see Manager Setup). This way only registered users can access the Network Rendering on that specific manager.
