Basic Block Diagram of Redundancy and Failure

Redundancy (Storage Sharing Configuration )

· If a failure of active server is detected in a shared storage replication configuration, the LifeKeeper module detects all failures (network, server, storage, application, and DB) and switches instantly to resume the service as soon as possible.

· Fast access of data is possible with shared storage configuration and data consistency that can be guaranteed using the SCSI PR3 reservation method in case of split-brain.

Redundancy (Storage Replication Configuration )

· If a failure of active servers is detected under a storage replication configuration, the LifeKeeper module detects all failures (network, server, storage, Application and DB), and switches instantly to resume the service as soon as possible.

· Data replication is able to guarantee data consistency because it is a synchronous replication.
