Single License Server Model
In the single license server model, the Network License Manager is installed
on a single server, so license management and activity is restricted to this
server. A single license file represents the total number of licenses available
on the server.
Advantages of the Single License Server Model
■ Because all license management takes place on a single server, you have
just one point of administration and one point of failure.
■ Of the three license server models, this configuration requires the least
amount of maintenance.
Disadvantage of the Single License Server Model
■ If the single license server fails, the Autodesk product cannot run until the
server is back online.
Distributed License Server Model
In the distributed license server model, licenses are distributed across more
than one server. A unique license file is required for each server. To create a
distributed license server, you must run the Network License Manager on each
server that is part of the distributed server pool.
Advantages of the Distributed License Server Model
■ Servers can be distributed across a wide area network (WAN); they do not
need to exist on the same subnet.
■ If one server in the distributed server pool fails, the licenses on the
remaining servers are still available.
■ If you need to replace a server in the distributed server pool, you do not
need to rebuild the entire pool.
■ Server replacement is easier than in a redundant server pool, where you
must reactivate the entire pool.
Disadvantage of the Distributed License Server Model
■ If a server in the distributed server pool fails, the licenses on that server
are unavailable.
