Because Retain is modular, component software can be installed on different servers, as the needs of your system dictate.
This is recommended for:
Small systems that aren’t expected to grow beyond a few hundred users.
This is recommended if
Your organization already has a dedicated database server.
Your users are assigned to several different post offices and/or messaging systems.
For medium to large systems, Micro Focus recommends assigning one worker agent per post office/messaging system (as applicable).
This is recommended if you have a very large system that requires high availability for searching the Retain archive.
The high-availability indexer requires a separate license and at least a 3-server cluster.
