Redundancy

eQuest servers can operate in cluster providing seamless software redundancy. This is possible with CARP technology (Common Address Redundancy Protocol) built-in nucleus of OpenBSD operating system. This unique solution allows the systems to dynamically distribute communication in group of servers that have the same IP address. One group of the servers (master) takes over the operation of communication reached to it, operating as a router synchronising data for other machines in the group at the same time. In the event of master failure, other server from the group smoothly takes over operation of overall movement directed under common IP. The application of XBMS server cluster is particularly important in facilities, which require continuous monitoring, e.g. hospitals.
