An optional Redundancy Server with a mirror database monitors all data activity on the primary EntraPass server and creates a real-time copy of the system database. In the event of primary server failure, the mirror database automatically launches the redundancy server which supports all the features and functionality of the primary server. Server redundancy means that, if a primary server is unavailable due to a power outage, network connection loss or other failure, a designated backup takes over and enables the application to continue to run. This applies to both configuration servers and service servers. Backup servers behave as clients until their designated primary fails. Network redundancy is a process through which additional or alternate instances of network devices, equipment and communication mediums are installed within network infrastructure. It is a method for ensuring network availability in case of a network device or path failure and unavailability. As such, it provides a means of network failover. In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
