Description of problem:
document still references out of date information

Version-Release number of selected component (if applicable):

Actual results:
Data storage domain
Data domains hold the virtual hard disk images of all the virtual machines running in the environment. Templates and snapshots of the virtual machines are also stored in the data domain. A data domain cannot be shared across data centers, and the data domain must be of the same type as the data center. For example, a data center of iSCSI type must have an iSCSI data domain.

Expected results:
Data storage domain
Data domains hold the virtual hard disk images of all the virtual machines running in the environment. Templates and snapshots of the virtual machines are also stored in the data domain. A data domain cannot be shared across data centers. The data center is now capable of supporting multiple types of data domains within the same data center. For example, a data center may contain both FC and iSCSI data domains.
