B.3. Storage Domain

Storage domains provide space for the storage of virtual machine disk images 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:
    • Fibre Channel Protocol (FCP)
    • Internet Small Computer System Interface (iSCSI)
    • Network File System (NFS)
  • All data storage domains within a data center must be of the same type. The type is specified as a step in the creation of the storage domain.
    • The data storage domain can be any of FCP, iSCSI, and NFS
    • Legacy FCP or iSCSI export storage domains from Red Hat Enterprise Virtualization 2.2 environments can be attached to data centers in Red Hat Enterprise Virtualization 3.0. New ISO and export storage domains must be provided by NFS.
Logical Unit Numbers (LUNs)
  • No more than 300 LUNs are permitted for each storage domain that is provided by iSCSI or FCP.

Note — Further Information

Further information about storage domains is available in the Red Hat Enterprise Virtualization Administration Guide.
