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. 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. 82 | Chapter 4 Licensing Guide
