Important The highly diverse scope of potential deployments makes it unrealistic to state recommended hardware requirements that would be generally applicable. Important If you create a virtual machine with the minimum supported hardware parameters 1 processor core and MB RAM and then attempt to install this release on the virtual machine, Setup will fail. To avoid this, do one of the following: Allocate more than MB RAM to the virtual machine on which you intend to install this release. Once Setup has completed, you can change the allocation to as little as MB RAM, depending on the actual server configuration.
In the command prompt that opens, use diskpart. Then close the command prompt and proceed with Setup. Note Be aware that 32 GB should be considered an absolute minimum value for successful installation. The system partition will need extra space for any of the following circumstances: If you install the system over a network.
Computers with more than 16 GB of RAM will require more disk space for paging, hibernation, and dump files. TPMs that implement version 2. Submit and view feedback for This product This page.

Three editions are available: Standard, Datacenter and Essentials.
The Datacenter version is intended for use in large-scale data centers, where you need to host and manage large fleets of virtual machines. Standard is the familiar small application server or operational database server, with limited virtualization requirements.
Smaller businesses with basic file and print needs, and up to 25 employees, can take the option of the Essentials release. Windows Server is available in the Microsoft Volume Licensing Center for customers with existing licensing agreements, or in the Azure Marketplace for use as an Azure virtual machine. Microsoft is licensing Windows Server using a per-core licensing model, with CALs required for users and devices accessing your servers.
Like Windows Server , licenses are sold in 2- and core packs with a minimum of 8 cores per processor and 16 core licenses per server. Be your company's Microsoft insider by reading these Windows and Office tips, tricks, and cheat sheets.

The best programming languages to learn in This section describes the accounts that can be configured to start SQL Server services, the default values used by SQL Server Setup, the concept of per-service SID's, the startup options, and configuring the firewall. The following table lists the default service accounts used by setup when installing all components.
The default accounts listed are the recommended accounts, except as noted. Managed service accounts, group-managed service accounts, and virtual accounts are designed to provide crucial applications such as SQL Server with the isolation of their own accounts, while eliminating the need for an administrator to manually administer the Service Principal Name SPN and credentials for these accounts.
These make long-term management of service account users, passwords and SPNs much easier. It is assigned to a single member computer for use running a service. The password is managed automatically by the domain controller.
When specifying an MSA, leave the password blank. Because an MSA is assigned to a single computer, it can't be used on different nodes of a Windows cluster. Windows manages a service account for services running on a group of servers. Active Directory automatically updates the group-managed service account password without restarting services. You can configure SQL Server services to use a group-managed service account principal. Servers with Windows Server R2 require KB applied so that the services can log in without disruption immediately after a password change.
For more information, see Group Managed Service Accounts. Virtual accounts beginning with Windows Server R2 and Windows 7 are managed local accounts that provide the following features to simplify service administration. The virtual account is auto-managed, and the virtual account can access the network in a domain environment. When specifying a virtual account to start SQL Server, leave the password blank.
Always run SQL Server services by using the lowest possible user rights. Use separate accounts for different SQL Server services. Don't grant additional permissions to the SQL Server service account or the service groups. Permissions are granted through group membership or granted directly to a service SID, where a service SID is supported.
In addition to having user accounts, every service has three possible startup states that users can control:. The startup state is selected during setup. When installing a named instance, the SQL Server Browser service should be set to start automatically. The following table shows the SQL Server services that can be configured during installation.
For unattended installations, you can use the switches in a configuration file or at a command prompt. Connections from other computers may not be possible until the Database Engine is configured to listen on a TCP port, and the appropriate port is opened for connections in the Windows firewall. The per-service SID is derived from the service name and is unique to that service.
Service isolation enables access to specific objects without the need to run a high-privilege account or weaken the security protection of the object. If the account used to start the Analysis Services service is changed, SQL Server Configuration Manager must change some Windows permissions such as the right to log on as a service , but the permissions assigned to the local Windows group is still available without any updating, because the per-service SID hasn't changed. This method allows the Analysis Services service to be renamed during upgrades.
Depending on the service configuration, the service account for a service or service SID is added as a member of the service group during install or upgrade. The account assigned to start a service needs the Start, stop and pause permission for the service.
SQL Server service accounts must have access to resources. Access control lists are set for the per-service SID or the local Windows group. For failover cluster installations, resources on shared disks must be set to an ACL for a local account.
When database files are stored in a user-defined location, you must grant the per-service SID access to that location. Some access control permissions might have to be granted to built-in accounts or other SQL Server service accounts.
The default drive for locations for installation is system drive , normally drive C. This section describes additional considerations when tempdb or user databases are installed to unusual locations. When installed to a local drive that isn't the default drive, the per-service SID must have access to the file location.
SQL Server Setup provisions the required access. When databases are installed to a network share, the service account must have access to the file location of the user and tempdb databases.
