GalaxyVisions HA (High Availability) Cluster Solution
GalaxyVisions 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, GV Cluster performs functions such as redundant resources management, failure detection, isolation and recovery, logging and notification tasks. GalaxyVisions 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. GalaxyVisions HA Cluster solution is designed to take real-time actions to resolve real-time nonstandard events. High Availability 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.
Features
Automatic Detection: Allows two servers to continually monitor each other for breakdowns and/or irregularities. If one of the servers should fail, the other one will automatically take over.
Automatic Switch-over: When HA detects an irregularity, recovery routines are immediately implemented. If the irregularity cannot be resolved locally, operations are switched to other server.
Automatic Recovery: Once the failed server is repaired, the administrative person can choose to initiate either an automatic or manual recovery process.
Load Balancing: With HA configured for "Dual Active" configuration, both servers will share in the network workload resulting an increase in network efficiency.
Automatic or manual failover: In addition to Automatic failover, GalaxyVisions HA Solutions can be configured for manual failover. This feature frees up one of the servers to perform functions such as trouble shooting, upgrading and/or scheduled maintenance without causing long interruptions to one or more client applications.
Automatic Notification: When irregularities or a breakdown occur, GalaxyVisions HA Solution will automatically notify pre-selected personal via page or fax messages.
