Cluster Shared Volumes ( CSV ) is a feature of Failover Clustering first introduced in Windows Server 2008 R2 for use with the Hyper-V role. A Cluster Shared Volume is a shared disk containing an NTFS or ReFS (ReFS: Windows Server 2012 R2 or newer) volume that is made accessible for read and write operations by all nodes within a Windows Server Failover Cluster.

The Cluster will automatically prioritize the most favorable network to route I/O operations by selecting the cluster shared network with the lowest cluster network metric value, this can also be manually configured. Public networks (i.e. networks that connect to users) are assigned higher cluster network metric values by default; this favors I/O operations from using

Cluster Shared Volumes simplifies storage management by allowing large numbers of VMs to be accessed off a common shared disk. CSV also increases
120-740: The cluster. Cluster Shared Volumes operates by orchestrating metadata I/O operations between the nodes in the cluster via the Server Message Block protocol. The node with ownership of the LUN orchestrating metadata updates to the NTFS volume is referred to as the Coordinator Node. Read / Write operations are passed directly to the Serial attached SCSI , iSCSI , Fibre Channel , or Fibre Channel over Ethernet shared storage via block based protocols. CSV builds
132-500: The physical disk resource does not need to be moved between nodes. CSV increases the chance that a live migration will complete within the TCP reconnect window and ensure a seamless operation to clients. To use CSV, a Hyper-V VM is configured and the associated virtual hard disk (s) are created on or copied to a CSV disk. Multiple VHDs can be placed on a CSV that in turn are associated with multiple VMs which can be running on different nodes in

While CSV is not required for Live Migration of VMs, it reduces the potential disconnection period at the end of the migration since the NTFS file system does not have to be unmounted/mounted as is the case with a traditional cluster disk. This helps ensure seamless live migration since
