Your NEC ExpressCluster X Edition provides synchronous data mirroring between two (or more) servers. Fast application recovery and data protection is ensured in case of a system failure.

Clustering ensures that your Security Center server’s configuration files and database files found on one server are mirrored on another server.

A virtual IP address is used to accept incoming client connections. The cluster then monitors the active server’s hardware and software. If a failure is detected, the cluster replaces the active server with the standby server so that the system remains online. Clients do not know whether the active server or the standby server is managing the system as they are still connected to the same IP address.
