RoseHA dual machine high availability cluster ensures continuous operation of business applications

The two servers (hosts) of the RoseHA dual machine system are directly connected to the disk array (shared storage) system. The user's operating system, application software, and RoseHA high availability software are installed on the two hosts, and shared data such as databases are stored on the storage system. The two hosts are connected through a private heartbeat network. After the configured system host starts working, RoseHA software starts monitoring the system. Through the heartbeat information transmitted through the private network, RoseHA software on each host can monitor the status of another host. When the work host fails, the heartbeat information will change, which can be captured by RoseHA software through a private network. When RoseHA captures this change, it will control the system to perform host switching, that is, the backup machine will start the same application as the work host to take over the work of the work host (including providing TCP/IP network services, storage system access and other services) and issue an alarm, prompting the administrator to repair the faulty host. After the repair is completed, it can be automatically or manually switched back according to RoseHA's settings, or not switched at all. At this time, the repaired host will be used as a backup machine, and the dual machine system will continue to work.

Automatic response to faults

RoseHA monitors the operational status of the system in real-time. In the event of hardware failure, application software abnormalities, operating system downtime, or human error, it will automatically switch to backup operation, achieving 24/7 uninterrupted operation of critical business for the enterprise.

Comprehensive monitoring system

Real time monitoring of the running status of application services, and automatic switching of application services to backup machines in case of any abnormalities.

Deeply monitor CPU/memory resource usage, with intelligent warning and policy switching capabilities.

Continuously monitor network resources, such as business network cards or network resource failures, and automatically switch resources to available backup machines.

Intelligent data protection mechanism

Our self-developed kernel level backup machine lock effectively prevents the backup machine from accidentally manipulating disk data.

Fully utilize resources

Support heterogeneous servers, quickly build hot standby clusters using existing production systems, and improve investment utilization.

Support deployment modes of primary backup and primary primary to reduce hardware investment costs.

Supporting physical and virtual machine operating environments, flexible deployment methods, easy construction of P-P, V-V, P-V, V-P deployment modes, more widely applicable to physical and virtual machine operating environments.

WEB management interface

Adopting a user-friendly wizard style configuration method. Simplified installation configuration, web-based management console, providing more convenient management and monitoring, supporting cross platform remote management, such as managing Linux platform hot standby clusters through Windows system clients.

Online expansion and upgrade

The new RoseHA supports online expansion and upgrading to cluster level disaster recovery solutions, improving the data security protection level of the cluster and further meeting the requirements of the Equal Protection 2.0 standard.

Comprehensive and friendly compatibility and adaptation

The fifth generation HA technology provides better adaptability, reduces the difficulty of selecting solutions, supports domestic CPUs and operating systems, and supports environments such as cloud platforms, virtualization, and hyper fusion.
