text: The storage set must support the number of days that you plan to maintain reports in the 
  application group. For example, if you must maintain reports in archive storage for seven 
  years, the storage set must identify a storage node (or migration policy on an IBM i server) 
  that is maintained by ASM for seven years. 
  
  A detailed description of adding storage sets and storage nodes is in Chapter 5, “Storage 
  management” on page 89 and the related*OnDemand Administrative Guide.*
  
  **10.2.1 Storing the report (document) data**
  
  To improve efficiency and scalability, stored documents are embedded within storage objects. 
  The storage objects are then stored in cache or a storage manager (OAM, Tivoli Storage 
  Manager, or ASM). The storage objects are eventually expired from the system based on 
  values that are defined by the Content Manager OnDemand administrator. In this section, we 
  describe each scenario and how it is implemented. The parameters that are described in this 
  section are on the Storage Manager tab of the Application Group window unless otherwise 
  specified. 
  
  Three sets of data are stored when you load a report: 
  
  (cid:2) Index data, which is extracted by the indexing program and used by the search process 
  (cid:2) Resources, such as an overlay and fonts, which are used to customize the viewed data 
  (cid:2) Documents (or report segments) that will be viewed
