SQL Server 2019: Hardware and software requirements

APPLIES TO: YesSQL Server (Windows only) NoAzure SQL Database NoAzure Synapse Analytics (SQL DW) NoParallel Data Warehouse

The article lists the minimum hardware and software requirements to install and run SQL Server 2019 on the Windows operating system.

For hardware and software requirements for other versions of SQL Server, see:

Hardware requirements

The following memory and processor requirements apply to all editions of SQL Server:

Component Requirement
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.
Monitor SQL Server requires Super-VGA (800x600) or higher resolution monitor.
Internet Internet functionality requires Internet access (fees may apply).
Memory * Minimum:

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.

Software requirements

The following requirements apply to all installations:

Component Requirement
Operating system Windows 10 TH1 1507 or greater

Windows Server 2016 or greater

.NET Framework Minimum operating systems 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:

  • SQL Server Native Client
  • SQL Server Setup support files


There are additional hardware and software requirements for the PolyBase feature. For more information, see Get started with PolyBase.

Operating system support

The following table shows which editions of SQL Server 2019 are compatible with which versions of Windows:

SQL Server edition: Enterprise Developer Standard Web Express
Windows Server 2019 Datacenter Yes Yes Yes Yes Yes
Windows Server 2019 Standard Yes Yes Yes Yes Yes
Windows Server 2019 Essentials Yes Yes Yes Yes Yes
Windows Server 2016 Datacenter Yes Yes Yes Yes Yes

Windows 10 Professional No Yes Yes No Yes
Windows 10 Home No Yes Yes No Yes

Server core support

Installing SQL Server 2019 on Server Core mode is supported by the following editions of Windows Server:

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.

Cross-language support

For more information about cross-language support and considerations for installing SQL Server in localized languages, see Local Language Versions in SQL Server.

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.
  • A SQL Server failover cluster instance is not supported in an environment where only a read-only domain controller is accessible.

Installation media

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.
