Failover process

If a network disk fails or applications, logs, or data cannot be retrieved locally, a process can be available automatically on the hot standby node, where these resources have been replicated and are immediately available. The maximum loss of any given resource depends on the frequency of replication of information. Further, if a node fails due to CPU load, an operating system, or power failure, or due to a JVM failure, the process can be available on a hot standby node. Finally, if the network fails, a backup network connection can be made available. If the backup network is also experiencing difficulties, a process can become available on a hot standby node on a different network.
