Installing [!INCLUDE sssql19-md] on Server Core mode is supported by the following editions of Windows Server:
:::row::: :::column::: Windows Server 2025 Core :::column-end::: :::row-end::: :::row::: :::column::: Windows Server 2022 Core :::column-end::: :::row-end::: :::row::: :::column::: Windows Server 2019 Core :::column-end::: :::row-end::: :::row::: :::column::: Windows Server 2016 Core :::column-end::: :::row-end::: :::row::: :::column::: :::column-end::: :::row-end:::
For more information on installing [!INCLUDE ssNoVersion] on Server Core, see [Install [!INCLUDE ssNoVersion] on Server Core](../../database-engine/install-windows/install-sql-server-on-server-core.md).
Note
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 [!INCLUDE ssNoVersion] in localized languages, see [Local Language Versions in [!INCLUDE ssNoVersion]](../../sql-server/install/local-language-versions-in-sql-server.md).
During installation of [!INCLUDE ssCurrent], Windows Installer creates temporary files on the system drive. Before you run Setup to install or upgrade [!INCLUDE ssNoVersion], 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 [!INCLUDE ssNoVersion] 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 [!INCLUDE ssCurrent] components.
| Feature | Disk space requirement |
|---|---|
| [!INCLUDE ssDE] and data files, Replication, Full-Text Search, and Data Quality Services | 1480 MB |
| [!INCLUDE ssDE] (as above) with R Services (In-Database) | 2744 MB |
| [!INCLUDE ssDE] (as above) with PolyBase Query Service for External Data | 4194 MB |
| [!INCLUDE ssASnoversion] and data files | 698 MB |
| [!INCLUDE ssRSnoversion] | 967 MB |

| [!INCLUDE ssMDSshort] | 280 MB |
| [!INCLUDE ssNoVersion] 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
- [!INCLUDE ssNoVersion] 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 [!INCLUDE ssNoVersion] data files on them. See [Hard disk drive sector-size support boundaries in [!INCLUDE ssNoVersion]](https://support.microsoft.com/kb/926930) for more information on hard disk sector-size support in [!INCLUDE ssNoVersion]. Currently, the
ForcedPhysicalSectorSizeInBytesregistry key is required to successfully install SQL Server on some newer storage devices with system disk sector size greater than 4 KB. - [!INCLUDE ssNoVersion] 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 [!INCLUDE ssNoVersion] resource will fail to come online.
- [!INCLUDE ssNoVersion] 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 [!INCLUDE ssNoVersion] data files on them. See [Hard disk drive sector-size support boundaries in [!INCLUDE ssNoVersion]](https://support.microsoft.com/kb/926930) for more information on hard disk sector-size support in [!INCLUDE ssNoVersion]. Currently, the
- Shared Storage
- Storage Spaces Direct (S2D)
- SMB File Share
- SMB storage isn't supported for [!INCLUDE ssASnoversion] 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 [!INCLUDE ssNoVersion] using SMB file share as a storage option, see [Install [!INCLUDE ssNoVersion] with SMB Fileshare as a Storage Option](../../database-engine/install-windows/install-sql-server-with-smb-fileshare-as-a-storage-option.md).
Installing [!INCLUDE ssNoVersion] on a domain controller
For security reasons, don't install [!INCLUDE ssCurrent] on a domain controller. [!INCLUDE ssNoVersion] Setup doesn't block installation on a computer that is a domain controller, but the following limitations apply:
- You can't run [!INCLUDE ssNoVersion] services on a domain controller under a local service account.
- After [!INCLUDE ssNoVersion] is installed on a computer, you can't change the computer from a domain member to a domain controller. You must uninstall [!INCLUDE ssNoVersion] before you change the host computer to a domain controller.
- After [!INCLUDE ssNoVersion] is installed on a computer, you can't change the computer from a domain controller to a domain member. You must uninstall [!INCLUDE ssNoVersion] before you change the host computer to a domain member.
- [!INCLUDE ssNoVersion] failover cluster instances are not supported where cluster nodes are domain controllers.
- [!INCLUDE ssNoVersion] isn't supported on a read-only domain controller. [!INCLUDE ssNoVersion] Setup can't create security groups or provision [!INCLUDE ssNoVersion] service accounts on a read-only domain controller. In this scenario, Setup will fail.
- A [!INCLUDE ssNoVersion] 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:
- [[!INCLUDE ssNoVersion] evaluation center](https://www.microsoft.com/evalcenter/evaluate-sql-server-2019)
- Most recent cumulative updates
Alternatively, you can create an [Azure virtual machine already running [!INCLUDE ssNoVersion]](/azure/azure-sql/virtual-machines/windows/sql-vm-create-portal-quickstart) though [!INCLUDE ssNoVersion] on a virtual machine will be slower than running natively because of the overhead of virtualization.
