Manage Hyper-Converged Infrastructure with Windows Admin Center
Applies To: Windows Server 2019, Windows Server 2016
What is Hyper-Converged Infrastructure
Hyper-Converged Infrastructure consolidates software-defined compute, storage, and networking into one cluster to provide high-performance, cost-effective, and easily scalable virtualization. This capability was introduced in Windows Server 2016 with Storage Spaces Direct and Hyper-V.

What is Windows Admin Center
Windows Admin Center is the next-generation management tool for Windows Server, the successor to traditional "in-box" tools like Server Manager. It's free and can be installed and used without an Internet connection. You can use Windows Admin Center to manage and monitor Hyper-Converged Infrastructure running Windows Server 2016 or an Insider Preview build of Windows Server 2019.
Highlights of Windows Admin Center for Hyper-Converged Infrastructure include:
- Unified single-pane-of-glass for compute, storage, and soon networking. View your virtual machines, host servers, volumes, drives, and more within one purpose-built, consistent, interconnected experience.
- Create and manage Storage Spaces and Hyper-V virtual machines. Radically simple workflows to create, open, resize, and delete volumes; and create, start, connect to, and move virtual machines; and much more.
- Powerful cluster-wide monitoring. The dashboard graphs memory and CPU usage, storage capacity, IOPS, throughput, and latency in real-time, across every server in the cluster, with clear alerts when something's not right.
Windows Admin Center for Hyper-Converged Infrastructure is being actively developed by Microsoft. It receives frequent updates that improve existing features and add new features. Here’s what’s new in recent months:

Before you start
To manage your cluster as Hyper-Converged Infrastructure in Windows Admin Center, it needs to be running Windows Server 2016 or a preview build of Windows Server 2019, and have Hyper-V and Storage Spaces Direct enabled.
Windows Admin Center also offers a general-purpose management experience for any cluster supporting any workload, available for Windows Server 2012 and later. If this sounds like a better fit, when you add your cluster to Windows Admin Center, select Failover Cluster instead of Hyper-Converged Cluster.
Prepare your Windows Server 2016 cluster for Windows Admin Center
Windows Admin Center for Hyper-Converged Infrastructure depends on management APIs added after Windows Server 2016 was released. Before you can manage your Windows Server 2016 cluster with Windows Admin Center, you’ll need to perform these two steps:
- Verify that every server in the cluster has installed the 2018-04 Cumulative Update for Windows Server 2016 (KB4093120) or later. To download and install this update, go to Settings > Update & Security > Windows Update and select Check online for updates from Microsoft Update.
- Run the following PowerShell cmdlet as Administrator on the cluster:
Add-ClusterResourceType -Name "SDDC Management" -dll "$env:SystemRoot\Cluster\sddcres.dll" -DisplayName "SDDC Management"
You only need to run the cmdlet once, on any server in the cluster. You can run it locally in Windows PowerShell or use Credential Security Service Provider (CredSSP) to run it remotely. Depending on your configuration, you may not be able to run this cmdlet from within Windows Admin Center.
For deployments in non-English locales, there is a known issue in version 1804 of Windows Admin Center that prevents the Dashboard from loading (first time only). The workaround is to run
Add-ClusterResource -Name 'SDDC Management' -Group 'Cluster Group' -ResourceType 'SDDC Management' replacing 'Cluster Group' with the localized name, for example, 'Group du cluster' in French. This issue will be addressed in the next update.
Prepare your Windows Server 2019 cluster for Windows Admin Center
If your cluster runs an Insider Preview build of Windows Server 2019, the steps above are not necessary. Just add the cluster to Windows Admin Center as described in the next section and you're good to go! Download the latest preview build of Windows Server 2019.
Once your Hyper-Converged Infrastructure is deployed, you can manage it using Windows Admin Center.
Install Windows Admin Center
If you haven’t already, download and install Windows Admin Center. The fastest way to get up and running is to install it on your Windows 10 computer and manage your servers remotely. This takes less than five minutes. Download now or learn more about other installation options.

Frequently asked questions
Are there differences between managing Windows Server 2016 and Windows Server 2019 Insider Preview?
Yes. Windows Admin Center for Hyper-Converged Infrastructure receives frequent updates that improve the experience for both Windows Server 2016 and Windows Server 2019 Insider Preview. However, certain new features are only available for Insider Preview – for example, the toggle switch for deduplication and compression.
Can I use Windows Admin Center to manage Storage Spaces Direct for other use cases (not hyper-converged), such as converged Scale-Out File Server (SoFS) or Microsoft SQL Server?
Windows Admin Center for Hyper-Converged Infrastructure does not provide management or monitoring options specifically for other use cases of Storage Spaces Direct – for example, it can’t create file shares. However, the Dashboard and core features, such as creating volumes or replacing drives, work for any Storage Spaces Direct cluster.
What's the difference between a Failover Cluster and a Hyper-Converged Cluster?
In general, the term "hyper-converged" refers to running Hyper-V and Storage Spaces Direct on the same clustered servers to virtualize compute and storage resources. In the context of Windows Admin Center, when you click + Add from the connections list, you can choose between adding a Failover Cluster connection or a Hyper-Converged Cluster connection:
The Failover Cluster connection is the successor to the Failover Cluster Manager desktop app. It provides a familiar, general-purpose management experience for any cluster supporting any workload, including Microsoft SQL Server. It is available for Windows Server 2012 and later.
The Hyper-Converged Cluster connection is an all-new experience tailored for Storage Spaces Direct and Hyper-V. It features the Dashboard and emphasizes charts and alerts for monitoring. It is available for Windows Server 2016 and preview builds of Windows Server 2019.
Why do I need the latest cumulative update for Windows Server 2016?
Windows Admin Center for Hyper-Converged Infrastructure depends on management APIs developed since Windows Server 2016 was released. These APIs are added in the 2018-04 Cumulative Update for Windows Server 2016 (KB4093120), available as of April 17th 2018.
How much does it cost to use Windows Admin Center?
Windows Admin Center has no additional cost beyond Windows.
You can use Windows Admin Center (available as a separate download) with valid licenses of Windows Server or Windows 10 at no additional cost - it's licensed under a Windows Supplemental EULA.
Does Windows Admin Center require System Center?
Does it require an Internet connection?
Although Windows Admin Center offers powerful and convenient integration with the Microsoft Azure cloud, the core management and monitoring experience for Hyper-Converged Infrastructure is completely on-premises. It can be installed and used without an Internet connection.

Create a new virtual machine
- Click the Virtual Machines tool from the left side navigation pane.
- At the top of the Virtual Machines tool, choose the Inventory tab, then click New to create a new virtual machine.
- Enter the virtual machine name and choose between generation 1 and 2 virtual machines.
- Uou can then choose which host to initially create the virtual machine on or use the recommended host.
- Choose a path for the virtual machine files. Choose a volume from the dropdown list or click Browse to choose a folder using the folder picker. The virtual machine configuration files and virtual hard disk file will be saved in a single folder under the
\Hyper-V\[virtual machine name]path of the selected volume or path.
- Choose the number of virtual processors, whether you want nested virtualization enabled, configure memory settings, network adapters, virtual hard disks and choose whether you want to install an operating system from an .iso image file or from the network.
- Click Create to create the virtual machine.
- Once the virtual machine is created and appears in the virtual machine list, you can start the virtual machine.
- Once the virtual machine is started, you can connect to the virtual machine's console via VMConnect to install the operating system. Select the virtual machine from the list, click More > Connect to download the .rdp file. Open the .rdp file in the Remote Desktop Connection app. Since this is connecting to the virtual machine's console, you will need to enter the Hyper-V host's admin credentials.
Pause and safely restart a server
- From the Dashboard, select Servers from the navigation on the left side or by clicking the VIEW SERVERS > link on the tile in the lower right corner of the Dashboard.
- At the top, switch from Summary to the Inventory tab.
- Select a server by clicking its name to open the Server detail page.
- Click Pause server for maintenance. If it’s safe to proceed, this will move virtual machines to other servers in the cluster. The server will have status Draining while this happens. If you want, you can watch the virtual machines move on the Virtual machines > Inventory page, where their host server is shown clearly in the grid. When all virtual machines have moved, the server status will be Paused.
- Click Manage server to access all the per-server management tools in Windows Admin Center.
- Click Restart, then Yes. You’ll be kicked back to the connections list.
- Back on the Dashboard, the server is colored red while it’s down.
- Once it’s back up, navigate again the Server page and click Resume server from maintenance to set the server status back to simply Up. In time, virtual machines will move back – no user action is required.
Replace a failed drive
- When a drive fails, an alert appears in the upper left Alerts area of the Dashboard.
- You can also select Drives from the navigation on the left side or click the VIEW DRIVES > link on the tile in the lower right corner to browse drives and see their status for yourself. In the Inventory tab, the grid supports sorting, grouping, and keyword search.
- From the Dashboard, click the alert to see details, like the drive’s physical location.
- To learn more, click the Go to drive shortcut to the Drive detail page.
- If your hardware supports it, you can click Turn light on/off to control the drive’s indicator light.
- Storage Spaces Direct automatically retires and evacuates failed drives. When this has happened, the drive status is Retired, and its storage capacity bar is empty.
- Remove the failed drive and insert its replacement.
- In Drives > Inventory, the new drive will appear. In time, the alert will clear, volumes will repair back to OK status, and storage will rebalance onto the new drive – no user action is required.
