15.2 Global network management benefits
![[Figure]](GRAPHICS/F0000115.GIF)
Suppose you have NNMi deployed on multiple NNMi management servers in several geographic locations. You have these NNMi management servers discovering and monitoring the network to meet your discovery and monitoring needs. Using these existing NNMi management servers and configurations, you can designate specific NNMi management servers as global managers to display combined node object data without additional discovery or monitoring configuration changes.
The NNMi global network management feature enables multiple NNMi management servers to work together while managing different geographic areas of the network. You designate specific NNMi management servers as global managers to display combined node object data from two or more regional managers.
The NNMi global network management feature offers the following benefits:
Provides a central big-picture view of your corporate-wide network from the global manager
Easy to set up:
Each regional manager administrator specifies node object data from all nodes or from a specific group of nodes for inclusion at the global manager level.
Each global manager administrator specifies which regional managers are allowed to contribute information.
Generates and manages incidents independently on each server (generated within the context of the topology available on each server)
For details, see NNMi's Global Network Management Feature (NNMi Advanced) in NNMi Help.
Each group of dynamic network address translation (NAT) or dynamic port address translation (PAT) or dynamic network address and port translation (NAPT) requires an NNMi regional manager, in addition to a tenant that is unique within the entire NNMi global network management configuration. For details, see 13. Managing Overlapping IP Addresses in a NAT Environment and NNMi Help.
