SQL Server Requirements
This article outlines the essential hardware and software requirements for installing and running various versions of Microsoft SQL Server. Ensuring you meet these prerequisites is crucial for a stable and performant database environment.
General Considerations
- Operating System: SQL Server has specific compatibility requirements for Windows Server, Windows client operating systems, and Linux distributions. Always refer to the official documentation for the exact version you intend to install.
- Hardware: This includes CPU, RAM, and disk space. Requirements vary significantly based on the edition of SQL Server (Express, Standard, Enterprise) and the expected workload.
- Network: Proper network configuration is necessary for client connections and inter-server communication.
Hardware Requirements
The following are general guidelines. Consult the specific release notes for your SQL Server version for precise figures.
| Component | Minimum | Recommended |
|---|---|---|
| Processor | x64 Processor | Multi-core Processor (e.g., 4+ cores) |
| Memory (RAM) | 2 GB | 8 GB or more (depending on workload) |
| Hard Disk Space | 4.5 GB (for Database Engine) | 50 GB or more (for system databases, logs, and data files) |
| Display Resolution | 1024 x 768 | 1280 x 1024 or higher |
Note: The recommended hardware specifications are for typical production environments. High-availability configurations, large databases, or intensive analytical workloads may require significantly more powerful hardware.
Software Requirements
Key software components include:
- .NET Framework: Specific versions are required by SQL Server components.
- Internet Explorer: Required for some SQL Server Management Studio (SSMS) features.
- PowerShell: Required for certain management tasks and scripting.
- Windows Installer: Must be present for the installation process.
