About Domino partitioned servers
Domino partitioned servers allow multiple Domino servers to run on a single computer. The advantages of using Domino partitioned servers are to reduce hardware expenses and minimize the number of computers to administer. Each Domino partitioned server has its own Domino data directory and notes.ini file. All partitioned servers on a single computer share the same Domino program directory.
Use different user accounts for each partitioned server. With different users accounts, you can easily use commands such as nsd to clean up orphaned processes after a server crash. The database agent easily supports backups and restores of multiple server partitions with each using a different user account. It is possible to backup multiple Lotus partitions from a single NetBackup policy; however, back up each partition by using a separate data stream.
