About basic multiple-drive configuration
In a basic multiple-drive configuration, there are an equal number of read and write drives, one master server, and one media server. The storage units are attached to the host on which the media server resides. A duplication process runs for each read and write drive pair. If the master server and media server reside on different hosts, media duplication data is transferred over a network.
Figure: Increasing throughput using multiple drives shows a multiple-drive configuration performing a duplication process.
Note:
Only NetBackup Enterprise Server allows a master server and media server to reside on different hosts.
