Load-sharing redundancy is equivalent to parallel operating redundancy with one addition: the components all work together to handle the same load. When one component fails, the remaining operating components increase the amount of the load for which they are responsible so that the total load is still carried. As they handle more and more of the load, the remaining operating components age faster and fail sooner. For more information, see Load-Sharing Notes.

When selected, the system consists of subsystems with alternate components that help to keep the system operating successfully in case one or more of the original components fail. In this model, all units are active at all times. In the case of failure, backup units automatically take over when original units fail.

When selected (default), the system has no redundancy. The system consists of a series or chain of subsystems. If one subsystem fails, the entire system fails. When this type is selected, no properties for specifying redundancy information are available.

When selected, the system consists of subsystems with alternate components that help to keep the system operating successfully in case one or more of the original components fails. In this model, only the minimum units required for operation are active. If an active unit fails, a backup unit automatically activates to take over for the failed unit. Standby redundancy is equivalent to parallel operating except that the redundant components are not active. Activation occurs only upon failure of a primary component.
