Autodesk® Network License Manager

Redundant License Servers

In the redundant license server model, three servers are used. Licenses can be issued as long

as at least two license servers are functional. The Network License Manager is installed on

each server, and the license file is identical on each server.

Advantage of the Redundant License Server Model

 If one of the three servers fails, all licenses that are managed in the server pool are still

available.

 Redundant servers offer the highest level of fault tolerance of server failure but are

intolerant of infrastructure failure.

Disadvantages of the Redundant License Server Model

 If more than one server fails, no licenses are available.

 All three servers must reside on the same subnet and have reliable network

communications. The redundant server pool does not provide network fault tolerance.

(Recommendation is to have all servers in the same data center)

 Slow, erratic, or dial-up connections are not supported.

 If one of the three servers is replaced, the complete redundant server pool must be

rebuilt with new license files.

 If your Autodesk product supports license borrowing, and licenses are borrowed from a

redundant license server pool, you must restart the license server after you stop the

Network License Manager.

 It requires server-edition operating systems. Mixing server operating systems or using

workstation operating systems (such as Windows 2000, XP, Vista or Windows 7) is not

supported.

 Using one computer as both a redundant and single server is not possible.

 It is complex to administer.

 Unless you are actively monitoring the status of the servers, you may not know if one

server has failed.
