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.
Disadvantages of the Distributed License Server Model
■ If a server in the distributed server pool fails, the licenses on that server
are unavailable.
■ This model can require more time for setup and maintenance than other
models.
Redundant License Server Model
In the redundant license server model, three servers are configured to
authenticate license files. Licenses can be monitored and issued as long as at
least two license servers are still functional. The Network License Manager is
installed on each server, and the license file on each server is the same.
In the redundant license server model, all servers must reside on the same
subnet and have consistent network communications. (Slow, erratic, or dial-up
connections are not supported.)
