An NIE55 supports approximately 5,000 points from an N1 Network. If a system contains more points, consider using an NIE85, otherwise you may need to use multiple NIEs to migrate all the points to the Metasys system network. You can split the integration of several NCMs across multiple NIEs to provide scalability of the network. The following items apply when splitting an integration across multiple NIEs:
-
Only one N1 Migration object can exist per NIE.
-
Multiple NIEs can reference the same N1 Network.
-
We recommend mapping objects from an NCM to only one NIE. Mapping objects to more than one NIE can cause degradation in the NCM idle time.
-
We recommend mapping two to five NCMs to each validated NIE55. Mapping over five NCMs adversely affects the service times for each NCM mapped to the NIE.
