The shares could be on a file server, or on a scale-out file server cluster using any of the cluster-supported storage systems.

Troubleshooting using Windows Error Reporting. Alternatively, you can connect your cluster nodes with one network that’s constructed with teamed network adapters, redundant switches, redundant routers, or similar hardware that removes single points of failure.
If you connect cluster nodes with a single network, the network will pass the redundancy requirement in the Validate a Configuration Wizard. However, the report from the wizard will include a warning that the network should not have single points of failure. You can use shared storage that’s attached, and you can also use SMB 3.
In most cases, attached storage should contain multiple, separate disks logical unit numbers, or LUNs that are configured at the hardware level.
For some clusters, one disk functions as the disk witness described at the end of this subsection. Other disks contain the files required for the clustered roles formerly called clustered services or applications.
Storage requirements include the following:. This is still considered as High Availability option because it takes less time to be executed compared to a physical server environment, where you would need to wait until the whole server is repaired. Last but not least, Hyper-V failover clustering has perfect scalability. Shared storage: The most important thing here is to have shared storage as a starting point. Since VM disks will not be moved to different storage, your storage should be able to work simultaneously with multiple hosts and provide them with read and write access.
Note: Shared storage is, in this case, still a single point of failure. Please note, there is no reason to attempt building failover cluster in a mixed environment.
Either Intel or AMD. Using chips from different CPU families, even from the same company, will also end up decreasing your chances to make the technology work. The best practice is to use identical chips. Networking: Besides connection to the shared storage, nodes should be interconnected with each other by some network.
Besides that, those servers must have either a full installation or a Server Core one. OS settings: From the settings point of view, servers should be joined to the same domain. In addition, they should have activated and installed Hyper-V and Failover Cluster roles with all dependences required within the installation. Figure 1. I joined them to the same domain and created a shared 10GB disk to use as the cluster shared volume CSV. Figure 2.

Also, if the failover cluster validation tests recognize that one or more nodes have the Hyper-V role installed, the Hyper-V configuration function is performed.
