Redundant servers are a system of three servers that work as a team to manage a single pool of floating license keys. If one of the servers goes down, the other two license servers automatically continue managing the license pool.
When one of the redundant license servers is not accessible, you might need to increase the server wait time for a client. The amount to increase the server wait time is dependent on your environment. For information about setting the server wait time, see Changing the disconnect time-out to delay disconnected use.
