Multiple Logical Targets
Generally, the host system contains the host database and a target database, and 
each target system contains a target database. However, you can put the target 
databases on the host system if it is network connected, or put several target 
databases on one target. A remote target system is not network connected to the host 
system. In that case, the target database must reside on the target system, and it must 
be running SQL/MP. 
In a multiple system environment.
A NonStop S-series host system running the DSM/SCM T6031G02 or a 
superceding RVU can manage any NonStop S-series systems running any earlier 
DSM/SCM product versions and Integrity NonStop systems. 
An Integrity NonStop host system running the DSM/SCM H01 product version can 
manage only Integrity NonStop systems. It cannot manage a NonStop S-series 
system.
Multiple Logical Targets
You can configure multiple logical targets on each system. For example, to have 
separate development and production disks on a system, you would have two logical 
targets on that system. You might also have a separate logical target for two different 
RVUs.
