In the R2 version of Hyper-V, Microsoft introduced a new concept of shared storage that can be used

to store data from virtual machines. This concept is called Cluster Shared Volume (CSV). Since CSV

needs to be accessible from all servers that are in the Hyper-V cluster, the virtual volume on which

CSV will be created must be exported to all these servers. In order to take advantage of Hyper-V

feature, it is recommended to always use CSV for virtual machine storage. The setup used for

developing this white paper is shown in the

Figure 41.

Licensing

For each Microsoft Hyper-V cluster environment it is required to have one On-line Extension for ONE

Windows / Linux system license. In addition, it is needed to have as many terabytes of Windows

Zero Downtime Backup licenses as the size of all CSVs, virtual volumes, which are going to be

protected.
