Redundant servers are a system of three servers that work together to manage a single pool of floating license keys. If one of the servers goes down, the other two license servers automatically continue to manage the license pool.
For a redundant servers configuration, where three servers are used, type each host name in this format: hostname1, hostname2, hostname3, where hostname is the name of the server. For each port number, type accordingly: host1port#, host2port#, host3port#, where # is the port number.
