Storage overview

Storage for Hyper-V is not primarily about capacity; it is about performance. Stop thinking in terms of capacities such as gigabytes and terabytes of data and calculate in IOPS from now on when Hyper-V Storage options are on the table. Of course, you still need to make sure there is enough capacity available. However, these typically neither influence the design nor the costs on a larger scale since high capacity hard drives are available for a very low price. There are very different approaches for a virtualization storage design.

In older versions of Windows Server and other virtualization products, a NAS system for smaller environments and enterprise-grade SAN systems were used as a storage backend. With a Fibre Channel or iSCSI connection to the Virtualization Server Systems, it provides a central storage for all nodes in a cluster, ensuring capabilities such as VM live migration and Cluster Failover.

The loss of cluster nodes does not impact the integrity and availability...
