Applications in mutual failover with crossed data replicationSafeKit HA software provides a simple active-active cluster with Windows or Unix applications running on two servers in mutual failover. In a SafeKit active-active cluster, each server is backup of the other server. And each application works on its own replicated file directories.
If one server fails in an active/active cluster, all applications will be active on the same physical server. After restart of the failed server, applications will return to run on their default primary server. 
The SafeKit active-active cluster is simply configured by deploying several mirror modules on the same servers. Each mirror module contains its own configuration of virtual IP address, replicated directories and restart scripts. As presented in the demo on the right, an active-active cluster can implement data replication for directories inside the operating system disk. The solution is much more simple and flexible than a hardware failover cluster. More information:
