Business Continuity and Data Security Assurance Solution RoseMirrorHA is a dual-server high availability solution based on real-time data mirroring or shared disks. Users can enhance a single-server setup by adding a second server or by adding a second server and a disk array to achieve a flexible dual-server high availability system. In this high availability solution, the operating system and applications are installed on the local system disks of both servers. The entire network system’s data is managed and backed up through a centralized disk array. User data is stored on an external shared disk array, ensuring that if one server fails, the backup server will actively take over, guaranteeing uninterrupted network services.
