Nutanix Volumes allows administrators to provision a volume group with one or more volumes that can be attached to multiple VMs or physical servers via iSCSI. This enables the creation of a Microsoft Server Failover Cluster that uses shared storage for a critical application. 

Microsoft Server Failover Cluster typically uses shared block storage for its quorum disk and application data. Nutanix Volumes provides this via iSCSI by provisioning a Volume Group, which can be accessed by both the AHV-hosted VMs and bare metal servers. This setup ensures maximum resiliency, as the shared storage is accessible to all nodes in the cluster, allowing failover between VMs and bare metal servers as needed.

Exact Extract from Nutanix Documentation:

From the Nutanix Volumes Administration Guide (available on the Nutanix Portal):

“Nutanix Volumes provides block storage via iSCSI, which is ideal for Microsoft Server Failover Clusters requiring shared storage. To deploy an MSFC with VMs and bare metal servers, provision a Volume Group in Nutanix Volumes and expose it via iSCSI to all cluster nodes, ensuring shared access to the storage for high availability and failover.”
