What is CSV network?
Cluster Shared Volumes (CSV) enable multiple nodes in a Windows Server failover cluster or Azure Stack HCI to simultaneously have read-write access to the same LUN (disk) that is provisioned as an NTFS volume. CSV also help simplify the management of a potentially large number of LUNs in a failover cluster.
What is csv file in Hyper-V?
Cluster Shared Volumes are a Windows Server feature introduced with Windows Server 2008R2. CSVs allow a cluster of Hyper-V servers to share a set of disks or volumes. Any host in the cluster can access any of the shared disks, and any of the guests on those disks.
Is the iSCSI network in a cluster used for cluster communications?
iSCSI: If you are using iSCSI, each clustered server should have one or more network adapters or HBAs that are dedicated to the cluster storage. The network you use for iSCSI should not be used for network communication.
How do I create a cluster shared volume server 2019?
Creating a CSV in WSFC ^ To add a disk/LUN to CSVs, navigate to your Hyper-V cluster > Disks > right-click your disk > Add to Cluster Shared Volumes. After clicking the Add to Cluster Shared Volumes option, you will quickly see the Assigned To column to change the storage Cluster Shared Volume.
What is cluster shared volume in Hyper-V?
Cluster Shared Volumes allow multiple Hyper-V hosts to have simultaneous read-write access to the same shared storage. When a given node performs disk I/O, the node is communicating directly with the storage appliance.
What is scaled file server?
Scale-Out File Server is designed to provide scale-out file shares that are continuously available for file-based server application storage. Scale-out file shares provides the ability to share the same folder from multiple nodes of the same cluster. All file shares are simultaneously online on all nodes.
What is pass through disk in Hyper-V?
Hyper-V provides a simple way to migrate pass-through disks to a flexible . vhd or . vhdx file format on virtual machines. A pass-through disk refers to a physical hard disk that is directly attached to a virtual machine.
What is heartbeat in Hyper V?
The heartbeat service allows the parent partition to detect when a virtual machine has locked up, crashed or otherwise ceased to function. The parent partition sends heartbeat messages to the guest operating system at regular intervals.
Which cluster network is used only by cluster nodes to communicate with each other?
Private network: used by cluster nodes to communicate with each other.
Why must you add a disk as a cluster shared volume?
In a cluster without CSV, only one node can access a disk LUN at a time, so multiple disks are required for migration. With Cluster Shared Volumes, storage is simplified because multiple nodes can access the same disk at once and fewer overall disks are needed.
How is CSV used in a Hyper-V cluster?
There is also resiliency built into CSV including I/O fault detection allowed for alternate communication paths to be used in the event of communication failures that might be detected.

What do you need to know about Hyper-V networking?
Hyper-V and Networking within a Cluster Failover Clustering has its own special networking needs, and Hyper-V extends those requirements further. Each node begins with the same requirements as a standalone Hyper-V system: one management adapter and a virtual switch. A cluster adds the need for cluster-related traffic and Live Migration.
When was clustered shared volume introduced in Hyper-V?
The clustered shared volume or CSV was introduced in Windows Server 2008 R2 and was designed to be used with the Hyper-V role so that a virtual machine can have VHD files accessed by any node in the cluster.
Why is CSV traffic set for cluster network?
So based on the metric, the CSV Traffic will now be set for the CSV Cluster network because it’s the lowest metric. The other change you would want to do is change the network that’s set for the Live Migration network.
