Hardware and Software Requirements for Installing SQL Server
The article lists the minimum hardware and software requirements to install and run SQL Server on the Windows operating system.
SQL Server 2017 (14.x) introduced support for SQL Server on Linux. For information, see Hardware and Software Requirements for SQL Server on Linux.
Try it out:
Download SQL Server from the Evaluation Center.
Spin up a Virtual Machine with SQL Server 2017 already installed.
The following considerations apply to all editions:
We recommend that you run SQL Server on computers with the NTFS or ReFS file formats. Installing SQL Server on a computer with FAT32 file system is supported but not recommended as it is less secure than the NTFS or ReFS file systems.
SQL Server Setup will block installations on read-only, mapped, or compressed drives.
Installation fails if you launch setup through Remote Desktop Connection with the media on a local resource in the RDC client. To install remotely the media must be on a network share or local to the physical or virtual machine. SQL Server installation media may be either on a network share, a mapped drive, a local drive, or presented as an ISO to a virtual machine.
SQL Server Management Studio installation requires installing .NET 4.6.1 as a prerequisite. .NET 4.6.1 will be automatically installed by setup when SQL Server Management Studio is selected.
SQL Server Setup installs the following software components required by the product:
SQL Server Native Client
SQL Server Setup support files
For minimum version requirements to install SQL Server on Windows Server 2012 or Windows 8, see Installing SQL Server on Windows Server 2012 or Windows 8.
Hardware and Software Requirements
The following requirements apply to all installations:
|.NET Framework||SQL Server 2016 (13.x) RC1 and later require .NET Framework 4.6 for the Database Engine, Master Data Services, or Replication. SQL Server setup automatically installs .NET Framework. You can also manually install .NET Framework from Microsoft .NET Framework 4.6 (Web Installer) for Windows.
SQL Server 2019 (15.x) requires .NET Framework 4.6.2. Available from Download Center
For more information, recommendations, and guidance about .NET Framework 4.6 see .NET Framework Deployment Guide for Developers.
Windows 8.1, and Windows Server 2012 R2 require KB2919355 before installing .NET Framework 4.6.
|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, TCP/IP, and VIA.
Note: VIA protocol is not supported on failover clusters. Clients or applications running on the same node of the failover cluster as the SQL Server instance, can use Shared Memory protocol to connect to SQL Server using its local pipe address. However this type of connection is not cluster-aware and will fail after an instance failover. It is therefore not recommended and should only be used in very specific scenarios.
Important: The VIA protocol is deprecated. This feature is in maintenance mode and may be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
For more information about Network Protocols and Network Libraries, see Network Protocols and Network Libraries.
|Hard Disk||SQL Server requires a minimum of 6 GB of available hard-disk space.
Disk space requirements will vary with the SQL Server components you install. For more information, see Hard Disk Space Requirements later in this article. For information on supported storage types for data files, see Storage Types for Data Files.
|Drive||A DVD drive, as appropriate, is required for installation from disc.|
|Monitor||SQL Server requires Super-VGA (800x600) or higher resolution monitor.|
|Internet||Internet functionality requires Internet access (fees may apply).|
Running SQL Server on a virtual machine will be slower than running natively because of the overhead of virtualization.
There are additional hardware and software requirements for the PolyBase feature. For more information, see Get started with PolyBase.
Processor, Memory, and Operating System Requirements
The following memory and processor requirements apply to all editions of SQL Server:
Express Editions: 512 MB
All other editions: 1 GB
Express Editions: 1 GB
All other editions: At least 4 GB and should be increased as database size increases to ensure optimal performance.
|Processor Speed||Minimum: x64 Processor: 1.4 GHz
Recommended: 2.0 GHz or faster
|Processor Type||x64 Processor: AMD Opteron, AMD Athlon 64, Intel Xeon with Intel EM64T support, Intel Pentium IV with EM64T support|
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.
WOW64 (Windows 32-bit on Windows 64-bit) is a feature of 64-bit editions of Windows that enables 32-bit applications to run natively in 32-bit mode. Applications function in 32-bit mode, even though the underlying operating system is a 64-bit operating system. WOW64 is not supported for SQL Server installations. However, Management Tools are supported in WOW64.
Server Core Support:
Installing SQL Server 2016 and 2017 on Server Core mode is supported by the following editions of Windows Server:
|Windows Server 2019 Standard||Windows Server 2019 Datacenter|
|Windows Server 2016 Standard||Windows Server 2016 Datacenter|
|Windows Server 2012 R2 Standard||Windows Server 2012 R2 Datacenter|
|Windows Server 2012 Standard||Windows Server 2012 Datacenter|
For more information on installing SQL Server on Server Core, see Install SQL Server on Server Core.

Hard Disk Space Requirements
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.
Storage Types for Data Files
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 may 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
- SQL Server failover cluster installation supports Local Disk only for installing the tempdb files. 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 is not 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.
Installing SQL Server on a Domain Controller
For security reasons, we recommend that you do not install SQL Server on a domain controller. SQL Server Setup will not block installation on a computer that is a domain controller, but the following limitations apply:
You cannot run SQL Server services on a domain controller under a local service account.
After SQL Server is installed on a computer, you cannot 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 cannot 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 is not supported on a read-only domain controller. SQL Server Setup cannot create security groups or provision SQL Server service accounts on a read-only domain controller. In this scenario, Setup will fail.
This restriction also applies to installations on domain member nodes.
A SQL Server failover cluster instance is not supported in an environment where only a read-only domain controller is accessible.
This restriction also applies to installations on domain member nodes.
