B.
primary storage deduplication

C.
virtual replication

D.
thin provisioning

Explanation:

Thin provisioning promises higher capacity utilization rates and is a feature in most storage systems.
But buyer beware—not all thin technologies are created equal. HP Converged Storage offers the
most comprehensive and advanced set of thin technologies in the industry. With HP, your data
center can be lean and efficient.
With HP thin technologies, you can:
* Start thin, so you can get the most from every dollar and disk.
Easily utilize 80% or more of your purchased capacity with thin provisioning, which, unlike
competitive offerings, does not require pre-planning or space reservations.
* Cut storage capacity needs in half—guaranteed.1
Changes IT refresh cycles by providing simple data mobility across clusters or generations of storage
systems without downtime.
* Expect high efficiency and high performance—not tradeoffs.

With HP 3PAR StoreServ Storage, thin technologies are embedded in hardware, so you can run all of
your workloads in a thin state and still have high performance.
* Reclaim nearly 100% of unused space.
HP’s thin reclamation technology continually hunts down wasted space in fine-grained, 16k
increments and returns that capacity to the system for use by other applications.
