Figure 6-3   Data separation at the object server level
6.3.3  Multiple archive servers
Data can be separated at the archive level. Typically, in this implementation, as illustrated in 
Figure 6-4, the application group (AG) data tables remain separate and User Group A’s data 
is stored on the Tivoli Storage Manager system A server, and User Group B’s data is stored 
on the Tivoli Storage Manager system B server. The two Tivoli Storage Manager servers are 
separate systems. This same type of separation is also possible by using object access 
method (OAM) on z/OS systems. OAM enables the separation of data by placing the data in 
different OAM collections on different storage devices.
