For example, dependencies on Active Directory Domain Services were removed. Support was added for the functional improvements in chkdsk , for interoperability with antivirus and backup applications, and for integration with general storage features such as BitLocker-encrypted volumes and Storage Spaces.

Windows Server R2 introduces additional functionality, such as distributed CSV ownership, increased resiliency through availability of the Server service, greater flexibility in the amount of physical memory that you can allocate to CSV cache, better diagnosability, and enhanced interoperability that includes support for ReFS and deduplication. For more information, see What’s New in Failover Clustering. Before using CSV in a failover cluster, review the network, storage, and other requirements and considerations in this section.

Multiple networks and multiple network adapters. To enable fault tolerance in the event of a network failure, we recommend that multiple cluster networks carry CSV traffic or that you configure teamed network adapters. If the cluster nodes are connected to networks that should not be used by the cluster, you should disable them.

To disable a network, in Failover Cluster Manager, select Networks , select the network, select the Properties action, and then select Do not allow cluster network communication on this network.

Network adapter properties. In the properties for all adapters that carry cluster communication, make sure that the following settings are enabled:. To enable SMB, also ensure that the Server service and the Workstation service are running and that they are configured to start automatically on each cluster node.

In Windows Server R2 and later, there are multiple Server service instances per failover cluster node. There is the default instance that handles incoming traffic from SMB clients that access regular file shares, and a second CSV instance that handles only inter-node CSV traffic. Also, if the Server service on a node becomes unhealthy, CSV ownership automatically transitions to another node. SMB 3. For more information, see Server Message Block overview.

The filter is disabled because it can cause issues with Hyper-V clusters which have a Guest Cluster running in VMs running on top of them. This can result in communication issues with the guest cluster in the VM. If you are deploying any workload other than Hyper-V with guest clusters, enabling the NetFT Virtual Adapter Performance Filter will optimize and improve cluster performance.

Cluster network prioritization. We generally recommend that you do not change the cluster-configured preferences for the networks. IP subnet configuration. If you want the memory to be dynamic, select the Use Dynamic Memory for this virtual machine check box. In Connection , select the NIC you want to assign to this virtual machine.

Click Next. The Connect Virtual Hard Disk window is displayed. In Name , enter a name for your virtual machine. This is the name that will be displayed in Hyper-V. In Location , enter a location on the cluster drive for the hard drive. Select the install location for your operating system.

If you intend to perform this installation at a later time, select Install an Operating System Later. This window displays the options that you have selected for the configuration of this Hyper-V machine. Review your selections and if you are happy with them, click Finish. When the Hyper-V machine has been configured, the Summary window displays a Success message. With the virtual machine turned off, in Hyper-V Manager , highlight the machine.

Expand Processor ; then click Compatibility. Select the Migrate to a physical computer with a different processor check box. Ensure that the new nodes are configured to accept the virtual machine in the event of a failover:.

In the Failover Cluster Manager , select Roles. On the General tab, under Preferred owners , select the nodes that you want to manage your virtual machine in the event of a failure. Specify Start Menu Folder. Enable the checkbox, if a desktop icon needs to be created. In the License key dialog box, provide the appropriate license key. Click Next. Click Browse… to locate the license file.

Press Next to continue. Review the licensing information. Verify the installation settings. Click Back to make any changes. Click Install to proceed with the installation. Click Finish to close the Wizard. StarWind Management Console will ask to specify the default storage pool on the server to which it connects for the first time. Configure the default storage pool to use one of the volumes that have been prepared previously. All devices created through the Add Device wizard will be stored on it.

In case an alternative storage path is required for StarWind virtual disks, use the Add Device advanced menu. Press the Yes button to configure the storage pool. If the storage pool destination needs to be changed, press Choose path… and point the browser to the necessary disk.

Other devices should be created in the same way. Right-click the Servers field and press the Add Server button. Select the StarWind server where the device needs to be created and press the Add Device advanced button on the toolbar. Add Device Wizard will appear. Select Hard Disk Device and click Next. Select Virtual Disk as a disk device type and click Next. Specify Virtual Disk Options and click Next. Define the caching policy and specify the cache size in GB.

The cache size should correspond to the storage working set of the servers. Define the flash cache parameters and size if necessary. Select the SSD location in the Wizard. Press Next. Specify the target parameters. Enable the Target Name checkbox to customize the target name. In this configuration, the cluster consists of two or more sites that can host clustered roles. If a failure occurs at any site, the clustered roles are expected to automatically fail over to the remaining sites. Therefore, the cluster quorum must be configured so that any site can sustain a complete site failure.

In this configuration, the cluster consists of a primary site, SiteA , and a backup recovery site, SiteB. Clustered roles are hosted on SiteA. Because of the cluster quorum configuration, if a failure occurs at all nodes in SiteA , the cluster stops functioning. In this scenario the administrator must manually fail over the cluster services to SiteB and perform additional steps to recover the cluster.

Note If you configure a file share witness or a cloud witness then shutdown all nodes for a maintenance or some reason, you have to make sure that start your cluster service from a last-man standing node since the latest cluster database is not stored into those witnesses.

Important It is usually best to use the quorum configuration that is recommended by the Configure Cluster Quorum Wizard. Note You can change the cluster quorum configuration without stopping the cluster or taking cluster resources offline.

Note You can also select Do not configure a quorum witness and then complete the wizard. Note You can also select No Nodes. Note You can also select Do not configure a quorum witness , and then complete the wizard. Note After you configure the cluster quorum, we recommend that you run the Validate Quorum Configuration test to verify the updated quorum settings.

It is always necessary to investigate why the cluster quorum was lost. It is always preferable to bring a node or quorum witness to a healthy state join the cluster rather than starting the cluster without quorum. Important After a cluster is force started, the administrator is in full control of the cluster. The cluster uses the cluster configuration on the node where the cluster is force started, and replicates it to all other nodes that are available.

If you force the cluster to start without quorum, all quorum configuration settings are ignored while the cluster remains in ForceQuorum mode. This includes specific node vote assignments and dynamic quorum management settings.

Important After a cluster is force started on a node, we recommend that you always start the remaining nodes with the quorum prevented. Note To force the cluster to start on a specific node that contains a cluster configuration that you want to use, you must use the Windows PowerShell cmdlets or equivalent command-line tools as presented after this procedure. If you use Failover Cluster Manager to connect to a cluster that is force started, and you use the Start Cluster Service action to start a node, the node is automatically started with the setting that prevents quorum.

If it is suitable for your cluster, and there is cluster shared storage available, the cluster selects a disk witness.

This option is recommended in most cases, because the cluster software automatically chooses a quorum and witness configuration that provides the highest availability for your cluster. You can add, change, or remove a witness resource. You can configure a file share or disk witness.
