A VDC application design dictates the use of multiple hypervisors with array LUNs that are directly
provisioned to each VM. The application data has an active lifetime of 6 to 9 months, after which it
is rarely accessed. The need is to re-purpose several storage arrays from different vendors and
performance capabilities.
Which technology should be considered for the VDC storage design?

A.
Block-level storage virtualization

B.
File-level virtualization with global namespace

C.
Thin-on-thin provisioning

D.
Intra-array storage tiering
