The triad redundant license model is appropriate for large installations that wish to ensure high availability of licenses by running 3 license servers in a special redundant configuration. The license is locked using the triad server's MAC addresses. The license information is stored in a license (certificate) file.
In principle, this configuration can be installed on a supported platform, and Linux is most commonly used. In this configuration, licenses can be accessed even if one license server fails. However, if two servers fail, the entire triad server fails and licenses can not be accessed. Due to the complexity of this model, it is recommended for institutions with prior experience running triad redundant FlexNet license servers.
In a redundant configuration, the primary server will act as the license server if at least one of the other servers is running. If the primary server fails, but the other two machines are up and running, then the secondary server takes over as the primary license server. When connecting to a triad license server, the product first attempts to connect to the primary server. If the software does not receive a response, it will try and connect with the secondary servers.
- The Ansys license manager is required on all 3 triad servers.
- The 3 triad servers should be on the same local network and running the same operating system and version of the Ansys license manager.
- The license file is required on all 3 triad servers.
Activate license and obtain a license file
- Activate your entitlement in the Ansys Licensing Portal (ALP) using the HostID information from the 3 license servers that will be running the Ansys license manager.
- See this Knowledge Base for more information on activating your entitlements in the ALP.
Transfer of license
- See this Knowledge Base for details on moving the entitlements to a different server in the Ansys Licensing Portal (ALP).
