Out of the box, Proxmox VE supports a variety of storage systems to store virtual disk images, ISO templates, backups, and so on. All plugins are quite stable and work great with Proxmox. Being able to choose different storage systems gives an administrator the flexibility to leverage the existing storage in the network. As of Proxmox VE 5.0, the following storage plugins are supported:

• The local directory mount points
• LVM
• LVM thin
• NFS
• iSCSI
• GlusterFS
• Ceph RADOS Block Devices (RBD)
• ZFS over iSCSI
• ZFS

We will learn the usage of different storage systems and the types of files they can store in detail in Chapter 4, Storage Systems.
