A. The physical space required by the eDevLUN data volume occupies the space of the local system

B. An eDevLUN data volume is a logical abstraction of external LUN data

C. In the SmartVirtualization, feature heterogeneous storage systems include only storage systems of other mainstream vendors.

D. LUNs in the SmartVirtualization heterogeneous storage systems are mapped to the local system.
Therefore, you can discover the LUNs in the local storage system. However, the data is not managed by the local storage system.
