Occasionally a database employs storage redundancy by database objects replication ( with one or more copies ) to increase data availability ( both to improve performance of simultaneous multiple end-user accesses to a same database object, and to provide resiliency in a case of partial failure of a distributed database ).

As a result of the introduction by IBM of their Geographically Dispersed Parallel Sysplex ( GDPS ) system, which allowed for an organization to manage end-to-end application and data availability across multiple geographically separate sites, an additional seventh tier was added to represent the industry's highest possible level of service availability.

By storing data across a selection of disks that are widely distributed across storage nodes, racks and sites, the DSS architecture spreads the risk of hardware failure to ensure that a failure of a component such as a disk, storage node or even a full rack has no impact on data availability and a minimal impact on data redundancy.
