Redundant Server Configuration

A redundant server configuration enables you to have three servers acting as one logical server managing a set of license tokens. This configuration requires that two of the redundant license servers be operative and able to contact each other. If the redundant servers cannot contact each other, none of the license tokens are available.

At any point, one of the redundant servers is the master server, the one that actually issues license tokens with a heavier processing load. If the master server is unavailable, then the next available peer in the configuration becomes the master server.

Once you have selected the machine to be used as a redundant license server, that machine cannot be used in a different licensing configuration.

The main advantage of redundant servers is an increased likelihood that if any tokens are available, then all tokens are available. The cost is increased installation and maintenance complexity.
