Hot Standby ROSEHA introduce multi-node

Hot Standby ROSEHA cluster using self-developed technology, enterprise network resources to provide more than one computer, effectively combined into a highly available cluster system to ensure multiple core applications continuous operation. It does this by running condition monitoring applications, databases, operating systems, storage resources, client access to resources and other kinds of computer software and hardware resources to achieve high availability core information systems. When a node is unavailable or perform operating system upgrades, application patches that require routine maintenance operations of the primary server is offline, RoseHA (multi-node) Software start monitoring system, through the private network to pass heartbeat information, each host two hot standby on the computer automatically RoseHA jobs to other available nodes in the cluster continues to operate effectively reduce planned and unplanned downtime, improve the business information system high availability and stability. Hot Standby ROSEHA use resource group management. The basic unit as a whole, the cluster resource group configuration, operation, management, fault automatically transferred, including end IP resources, volume resource, NT service resources, and some user-defined resources such as scripts, JAVA development programs.
