Storage sets and storage nodes
A storage set is a named collection of primary storage nodes that support application groups with similar storage management requirements, such as the length of time that files are maintained in the application group and the type of media on which the files are stored.
Most customers define one or two storage sets for a Content Manager OnDemand system, based on the storage requirements of the reports that they plan to store in the system. For example, you might define one storage set to maintain reports for a period of ten years and another storage set to maintain reports for a period of 180 days.
A storage set can contain one or more primary storage nodes. A primary storage node identifies an object server on which Content Manager OnDemand copies data to cache storage. A storage set can write data to one and only one primary storage node at a time.
When you define an application group, you assign the application group to a storage set. The storage set must support the storage requirements of the data that you plan to store in the application group.
