RHV storage is logically grouped into storage pools, which are comprised of three types of storage domains: data (vm and snapshots) , export (temporary storage repository that is used to copy and move images between data centers and RHV instances), and ISO.

The data storage domain is the only one required by each data center and exclusive to a single data center. Export and ISO domains are optional, but require NFS or POSIX.

Storage domains are shared resources and can be implemented using NFS, GlusterFS, POSIX, iSCSI or the Fibre Channel Protocol (FCP). On NFS, all virtual disks, templates, and snapshots are simple files. On SAN (iSCSI/FCP), block devices are aggregated into a logical entity called a Volume Group (VG). This is done using the Logical Volume Manager (LVM) and presents high performance I/O.

Luns can be directly attached to VMs as disks, but some feature are not supported when this option is used like snapshotting.

Local storage can be used to create non-shared local datacenter which allow a single host.
