Planning for Repository Database Growth
Go Up to Repository Installation
Regardless of the platform, allocate at least 300 MB of space to the database and implement auto extend so that the database can accommodate increases in the size and number of models. Also, allocate 50 MB of space to the database log file.
The table below describes the initial size of some sample Repository databases before any diagrams are added, and the approximate database sizing for sample small, medium, and large diagrams.
