Supported storage types for Proxmox Virtual Environment

PDFs
Proxmox Virtual Environment (VE) supports multiple storage protocols with NetApp ONTAP, including NFS and SMB for NAS and FC, iSCSI, and NVMe-oF for SAN. Each protocol supports different Proxmox VE content types including VM disks, backups, container volumes, ISO images, and templates.
NAS protocol support
NAS protocols (NFS and SMB) support all Proxmox VE content types and are typically configured once at the datacenter level. Guest VMs can use raw, qcow2, or VMDK disk formats on NAS storage. ONTAP snapshots can be made visible to clients for accessing point-in-time copies of data.
SAN protocol support
SAN protocols (FC, iSCSI, and NVMe-oF) are typically configured per host and support VM disk and container image content types in Proxmox VE. Guest VMs can use raw, VMDK or qcow2 disk formats on block storage.
