Understanding a redundant environment

Using two OpenSwitch servers in a high availability, warm standby environment provides additional robustness and a redundant environment. A redundant environment is one in which there is no single point of failure. The second OpenSwitch server protects the replication environment from the failure of the first OpenSwitch server by assuming control of the failover sequence in case the subsequent active database fails or Replication Server fails. See “Creating a redundant environment” for more information.

The second OpenSwitch server can provide secondary access to the active and standby databases. This enables you to load-balance the databases. To load-balance means using all servers simultaneously in the environment until a server fails. You can differentiate user access for each of the databases so that not all users connect to the same database and, thereby, balance the user connection load among databases.

See “DSS users” for more information about load balancing.
