Scaling limits
For the selection of the appropriate database connection, the following overview serves as a guide, which has to be defined in addition to the scaling limits of active ProCall Enterprise users or simultaneous calls (which was applicable earlier):
| Up to 250 users | Up to 10,000 users  | From 10,000 users |
|---|---|---|
| SQL Server Express , SQLite (integrated in ProCall 7 Enterprise) | SQL Server Standard, 2 Core | SQL Server Enterprise, 4 Core (Minimum) |
Multiple UCServer with separate databases, each with a maximum of 2,500 users per UCServer installation.
When selecting the appropriate Microsoft SQL Server Edition, the scale limitations of the databases must be taken into account and the configuration must be made accordingly in ProCall Enterprise and in the SQL Server. The scale limits of Microsoft SQL Server can be found in the following article Editions and supported features of SQL Server 2019 (15.x). For further planning, the following article can be used as a starting point: Planning an SQL Server Installation.
