Server Node Configuration

Previous Next

These three-server redundant servers should have excellent communications and should be on the same subnet. This often means that the three servers should be located physically close to each other. This form of redundancy requires that the servers exchange heartbeats periodically, and poor communications can cause poor performance. Redundant servers should not be configured with slow communications or dial-up links.

Three-server redundancy does not provide load-balance of licenses because with three-server redundancy, only one of the three servers is master, capable of issuing licenses. Because all clients must contact the master, all clients must have reliable networking to a single node.
