SDS and Hardware Clustering

SDS and hardware clustering are complementary technologies. Hardware cluster solutions address system failures. Clusters can also provide scalability options for an application; for example, JADE application server nodes can be allocated across machine nodes in the cluster. However, clusters do not provide any data protection since there is a single copy only of the database within the cluster, typically resident on a disk shared between the physical machine nodes.

SDS can be deployed to incorporate the missing level of database protection into an existing clustered environment.
