Genstor HA cluster solution is a high availability, business continuous, load balancing solution that allows two servers to be connected together forming a cluster. The function of this cluster is to keep data flowing even if one of the servers fails. To accomplish this failover mechanism, HA Cluster performs functions such as redundant resources management, failure detection, isolation and recovery, logging and notification tasks. Genstor HA based clusters can be configured for one of two operational modes, "Dual Active" or "Hot Standby". In the Dual Active mode both servers share the workload. If one of the servers fails, the remaining server automatically starts carrying the full workload. In the Hot Standby mode, one server is on line carrying the full workload and the other server is in a hot standby mode. If the online server should fail, the standby server will automatically come on line to take over the full workload. Genstor HA Cluster solution is designed to take real-time actions to resolve real-time nonstandard events. HA solution establishes a cost effective, highly efficient clustered environment for mission critical, business continuous applications, such as retail email servers, point-of-sale, online banking, claims processing, telemarketing, RDBMS, Internet and other transaction-oriented applications.
