RoseHA

The arbitration service is responsible for making decisions and coordinating the active and standby roles in the cluster, ensuring maximum continuity of business system.

The arbitration service can balance the requirements of business continuity and data consistency, enhancing the fault response and self-resuming capabilities of the cluster system, thus improving its availability. The arbitration node supports cooperation with multiple cluster groups simultaneously, reducing the deployment complexity of the arbitration node.

RoseHA will monitor the running system status in real time. In case of any HW fault, app software abnormity, OS downtime or man-made error, it will auto failover to standby server, so that enterprise can achieve 7X24h business continuity of key businesses. 

Monitor the running status of application service in real time. If any service errors, it will auto failover related application to standby server. 

Conduct in-depth monitoring on the usage of CPU/memory resource, and support intelligent alarm and failover. 

Continuously monitor the network resources. If the business NIC or network resources fail, it will auto failover related resources to standby server. 

The self-developed kernel-level standby server lock can effectively prevent the error operation on disk data of standby server. 

Support heterogeneous server. It can quickly build active-standby cluster on the basis of existing production system and promote investment utilization rate.

Support both active-standby and active-active modes of deployment mode and reduce HW investment. 

Widely support the operation environment for both physical and virtual servers. The deployment mode is flexible, like P-P，V-V，P-V and V-P. 

Apply friendly wizard to guide configuration. The installation and configuration are simplified. The web management platform provides convenient management and monitoring. Beside it supports cross-platform remote management. For example, user can manage the active-standby cluster on Linux platform from a Windows client.  

The brand new RoseHA supports online extension or upgrade to cluster-level disaster recovery solution, to promote cluster’s data security protection level and further satisfy the requirement of Cybersecurity Classified Protection Standards 2.0.

The fifth generation of HA technology provides better compatibility and reduces solution selection difficulty. Beside the localized CPU & OS, it also supports cloud platform, virtualization and hyper-convergence environments.
