Update: 30 September, 2023
SureHA is a high-availability cluster software that can build a highly reliable dual-machine system to protect data and services. SureHA supports master-slave and peer modes. In master-slave mode, one server is designated as the master server for critical operations, and the other server as a hot backup server. In peer mode, all servers are designated as the master server for their own critical operations. The two servers back each other up.
