SQL Server
The Express Edition of Microsoft SQL Server is not supported.
The system requirements for Microsoft SQL Server can be found in the official Microsoft manual. The requirements below apply in addition to these. For Machine Learning Services, see resource requirements. Network connection details are available in the Microsoft Server Network Configuration Guide.
| Component | Details |
|---|---|
| Version | - Microsoft SQL Server 2025 - Microsoft SQL Server 2022 - Microsoft SQL Server 2019 - Microsoft SQL Server 2017 |
| Editions | - Standard - Developer - Enterprise |
| Processor | - x64-based CPU |
| Storage | - SQL-Server: minimum 6GB - Data: minimum 500 GB recommended (depending on the amount of data) |
| RAM | - minimum 16GB, more GB RAM recommended - highly dependent on the amount of processed data |
Recommended Instance Topology
We strongly recommend using separate SQL Server instances for the Application Database and Extraction/Results databases. Running both on the same instance can cause connection timeouts and task status inconsistencies under heavy load.
For optimal stability, deploy two SQL Server instances:
| Instance | Purpose | RAM | vCPU | Storage |
|---|---|---|---|---|
| Application Database | Stores dab Nexus settings and task states | 4–8 GB | 2–4 | 10–20 GB |
| Extraction/Results | Stores extracted SAP data and analysis results | 16+ GB | 4+ | 500+ GB |
The Application Database instance handles lightweight read/write operations and does not require significant compute resources. The Extraction/Results instance must be sized according to your data volume.
For migration instructions if you are currently using a single instance, see Database Troubleshooting.
