10.4. Storage Domain Limitations
Storage domains provide space for the storage of virtual disks and ISO images as well as the import and export of virtual machines. While many storage domains may be created within a given data center, there are a number of limitations and recommendations that apply to each storage domain.
| Item | Limitations |
|---|---|
| Storage Types |
Supported storage types are:
New ISO and export storage domains in Red Hat Virtualization 4.1 can be provided by any file-based storage (NFS, Posix, or GlusterFS).
|
| Logical Unit Numbers (LUNs) | No more than 300 LUNs are permitted for each storage domain that is provided by iSCSI or FCP. |
| Logical Volumes (LVs) |
In Red Hat Virtualization, logical volumes represent virtual disks for virtual machines, templates, and virtual machine snapshots.
Red Hat Virtualization supports 1300 logical volumes per block-based storage domain.
