+{VirtProductName} integrates with the Container Storage Interface (CSI) to manage VM storage. Storage classes define storage capabilities such as performance tiers and types. PersistentVolumeClaims (PVCs) request storage resources, which bind to PersistentVolumes (PVs). CSI drivers connect Kubernetes to vendor storage backends, including iSCSI, NFS, and Fibre Channel.
