| Processor Type | x64 Processor: AMD Opteron, AMD Athlon 64, Intel Xeon with Intel EM64T support, Intel Pentium IV with EM64T support |
Notitie
Installation of SQL Server is supported on x64 processors only. It is no longer supported on x86 processors.
* The minimum memory required for installing the Data Quality Server component in Data Quality Services (DQS) is 2 GB of RAM, which is different from the SQL Server minimum memory requirement. For information about installing DQS, see Install Data Quality Services.

| Operating system | Windows 10 TH1 1507 or greater Windows Server 2016 or greater |
| .NET Framework | Minimum operating system includes minimum .NET framework. |
| Network Software | Supported operating systems for SQL Server have built-in network software. Named and default instances of a stand-alone installation support the following network protocols: Shared memory, Named Pipes, and TCP/IP. |
SQL Server Setup installs the following software components required by the product:
- Microsoft ODBC Driver 17 for SQL Server

Installing SQL Server 2019 (15.x) on Server Core mode is supported by the following editions of Windows Server:
Windows Server 2025 Core
Windows Server 2022 Core
Windows Server 2019 Core
Windows Server 2016 Core
For more information on installing SQL Server on Server Core, see Install SQL Server on Server Core.
Notitie
Installing SQL Server on a Windows OS on which case sensitivity is enabled isn't supported. For more information review SQL Server isn't supported on a Windows operating system on which case sensitivity is enabled
For more information about cross-language support and considerations for installing SQL Server in localized languages, see Local Language Versions in SQL Server.
During installation of SQL Server, Windows Installer creates temporary files on the system drive. Before you run Setup to install or upgrade SQL Server, verify that you have at least 6.0 GB of available disk space on the system drive for these files. This requirement applies even if you install SQL Server components to a non-default drive.
Actual hard disk space requirements depend on your system configuration and the features that you decide to install. The following table provides disk space requirements for SQL Server components.
| Feature | Disk space requirement |
|---|---|
| Database Engine and data files, Replication, Full-Text Search, and Data Quality Services | 1480 MB |
| Database Engine (as above) with R Services (In-Database) | 2744 MB |
| Database Engine (as above) with PolyBase Query Service for External Data | 4194 MB |
| Analysis Services and data files | 698 MB |
| Reporting Services | 967 MB |
| Microsoft R Server (Standalone) | 280 MB |
| Reporting Services - SharePoint | 1203 MB |
| Reporting Services Add-in for SharePoint Products | 325 MB |
| Data Quality Client | 121 MB |
| Client Tools Connectivity | 328 MB |
| Integration Services | 306 MB |
| Client Components (other than SQL Server Books Online components and Integration Services tools) | 445 MB |
| Master Data Services | 280 MB |
| SQL Server Books Online Components to view and manage help content* | 27 MB |
| All Features | 8030 MB |
*The disk space requirement for downloaded Books Online content is 200 MB.
The supported storage types for data files are:
- Local Disk
- SQL Server currently supports disk drives that have standard native sector sizes of 512 bytes and 4 KB. Hard disks with sector sizes larger than 4 KB might cause errors when attempting to store SQL Server data files on them. See Hard disk drive sector-size support boundaries in SQL Server for more information on hard disk sector-size support in SQL Server. For more information, see Troubleshoot errors related to system disk sector size greater than 4 KB.
- SQL Server failover cluster installation supports Local Disk only for installing the
tempdbfiles. Ensure that the path specified for the tempdb data and log files is valid on all the cluster nodes. During failover, if the tempdb directories are not available on the failover target node, the SQL Server resource will fail to come online.
- Shared Storage
- Storage Spaces Direct (S2D)
- SMB File Share
- SMB storage isn't supported for Analysis Services data files for either standalone or clustered installations. Use direct attached storage, a storage area network, or S2D instead.
- SMB storage can be hosted by a Windows File Server or a third-party SMB storage device. If Windows File Server is used, the Windows File Server version should be 2008 or later. For more information about installing SQL Server using SMB file share as a storage option, see Install SQL Server with SMB Fileshare as a Storage Option.
For security reasons, don't install SQL Server on a domain controller. SQL Server Setup doesn't block installation on a computer that is a domain controller, but the following limitations apply:
- You can't run SQL Server services on a domain controller under a local service account.
- After SQL Server is installed on a computer, you can't change the computer from a domain member to a domain controller. You must uninstall SQL Server before you change the host computer to a domain controller.
- After SQL Server is installed on a computer, you can't change the computer from a domain controller to a domain member. You must uninstall SQL Server before you change the host computer to a domain member.
- SQL Server failover cluster instances are not supported where cluster nodes are domain controllers.
- SQL Server isn't supported on a read-only domain controller. SQL Server Setup can't create security groups or provision SQL Server service accounts on a read-only domain controller. In this scenario, Setup will fail.
- A SQL Server failover cluster instance isn't supported in an environment where only a read-only domain controller is accessible.
You can get relevant installation media from the following locations:
Alternatively, you can create an Azure virtual machine already running SQL Server though SQL Server on a virtual machine will be slower than running natively because of the overhead of virtualization.
