Grass Valley Aurora Playout v.7.0 - Manual (Page 21)

Overview of the Housekeeper
Playback operators use Housekeeper to remove files from the clip database, import
files from media servers, and to archive clips.
Housekeeper typically runs on the computer with the Main Aurora Playout application,
though it can be installed on multiple computers if necessary.
Due to differences in media server channeless connection limit, not all computers
within your broadcast operation can run Housekeeper application at the same time. If
your media server is K2 version 3.2 and above, you can run up to seven Housekeeper
applications simultaneously. While for M-Series, Profile and K2 version 3.1 and lower;
only three Housekeeper applications can be run at the same time.
Overview of the Simple Database (SDB) Server
The SDB Server runs in the background to keep clip status current.
