If you choose the Network License option, you need to know which license server model will be used to distribute the product licenses. This was specified as one of the following when the license was purchased:

• Single license server model. The Network License Manager (NLM) is installed on a single server, so license management and activity is restricted to this server. A single license file records the total number of licenses available on the server.
• 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 NLM on each server that is part of the distributed server pool.
• Redundant license server model. Three servers are available to authenticate each license. With this configuration, licenses continue to be monitored and issued as long as at least two servers are functional. The license file on all three servers is the same, and you must run NLM on each server.

Each of these license server models is described in detail in the Licensing Guide. It is recommended that you also read that guide before you deploy the product. You can find the Licensing Guide by clicking the Installation Help link in the installer.
