Perfect for File Server and Web Server High Availability
File server and web servers have one thing in common: they are both expected
to be available when a network user needs to get information or get files from
them. Such super servers must be able to sustain interruption caused by natural
disasters, accidental or mechanical system failures, or human errors.
Cluster systems are built to satisfy this expectation. XLink's ClusterReplica
Standard edition binds two Windows systems together as the cluster server, which
is best applicable for web server and file servers. It will monitor the systems in the cluster system and the
pre-defined services to determine if the cluster system is in the
condition that a failover should be activated.
Failover is the process specifically associated to cluster
systems. Typically it means when the Primary station of a cluster
system dies, the Secondary station will be activated to take over
the active duty of the Primary station. This automation of Failover
ensures the high availability of the cluster server.
Here are some pictures to provide a general description of Failover (1)(2) and Failback (3)(4).
