Windows Server 2016 Standard Core Datacenter Core Refresh 2017
Windows Server 2016 is a server operating system developed by Microsoft as part of the Windows NT family of operating systems. It was released on September 26, 2016 and is the successor to Windows Server 2012 R2. Windows Server 2016 has two main editions: Standard and Datacenter, each with different features and licensing options. In this article, we will focus on the core versions of these editions and the refresh update that was released in 2017.
What are core versions of Windows Server 2016?
Core versions of Windows Server 2016 are installation options that provide a minimal environment for running specific server roles. They do not have a graphical user interface (GUI) or many other features that are available in the full versions of Windows Server 2016. Core versions are designed to reduce the attack surface, improve performance, and save disk space and resources. There are two core versions of Windows Server 2016: Server Core and Nano Server.
- Server Core is a core version that supports most server roles and features, such as Active Directory, DNS, DHCP, File Services, Hyper-V, and more. It has a command-line interface (CLI) and can be managed remotely using PowerShell, Server Manager, or other tools. Server Core is available for both Standard and Datacenter editions of Windows Server 2016.
- Nano Server is a core version that supports a subset of server roles and features, such as Hyper-V, Containers, DNS, IIS, and more. It has no local logon capability and can only be managed remotely using PowerShell or other tools. Nano Server is optimized for cloud applications and services, and has a smaller footprint than Server Core. Nano Server is only available for the Datacenter edition of Windows Server 2016.
What is the refresh update for Windows Server 2016?
The refresh update for Windows Server 2016 is an update that was released in August 2017 to address some issues and add some enhancements to the core versions of Windows Server 2016. The refresh update is also known as the KB4035631 update or the version 1709 update. Some of the changes that the refresh update introduced are:
- Nano Server was repositioned as a container image only, meaning that it can no longer be installed as a standalone operating system on physical or virtual machines. Instead, it can only be used as a base image for creating containers that run on Windows Server 2016 or Windows 10 hosts. This change reduced the size of Nano Server by more than 50%, making it faster to deploy and update.
- Server Core was enhanced with new features and capabilities, such as support for Linux containers, software-defined networking (SDN), storage spaces direct (S2D), shielded virtual machines (VMs), and more. These features were previously only available for the Datacenter edition of Windows Server 2016, but with the refresh update they became available for both Standard and Datacenter editions.
- Licensing was changed to align with the new features and capabilities of the core versions of Windows Server 2016. The licensing model for Windows Server 2016 is based on the number of processor cores in the server, with a minimum of 8 cores per processor and 16 cores per server. The refresh update introduced a new licensing option for Nano Server containers, which allows customers to pay only for the virtual cores (vCPUs) allocated to the containers.
How to upgrade or convert to the core versions of Windows Server 2016?
If you want to upgrade or convert to the core versions of Windows Server 2016, you need to consider some factors such as your current version and edition of Windows Server, your licensing options, and your desired server roles and features. Here are some general guidelines for upgrading or converting to the core versions of Windows Server 2016:
- If you have an evaluation version of Windows Server 2016, you can convert it to a retail version of either Standard or Datacenter edition using the DISM command-line tool. You can also choose to install either Server Core or Nano Server as your installation option.
- If you have a licensed version of Windows Server 2016, you can upgrade it to a newer version or a different edition using the Windows Setup wizard or the DISM command-line tool. You can only upgrade from Standard edition to Datacenter edition, not the other way around. You can also switch between Server Core and Server with Desktop Experience installation options, but not to Nano Server.
- If you have a licensed version of Windows Server 2012 R2 or earlier, you can perform a clean installation of Windows Server 2016 using the Windows Setup wizard or the DISM command-line tool. You can choose either Standard or Datacenter edition, and either Server Core or Nano Server as your installation option. You cannot perform an in-place upgrade from previous versions of Windows Server to the core versions of Windows Server 2016.
