For budgeting purpose, a customer wants to set aside all the storage for a particular workload which will run on
12 LPARs in Power E870. The CIO is worried that allocating all the storage to each LPAR from the beginning
can lead to lack of storage in long term.
How can Shared Storage Pools benefit this customer?

A.
Shared Storage Pools provide automatic data archiving tools that prevent overconsumption of the storage.

B.
When storing data on Shared Storage Pools, the data is automatically compressed to take less space.

C.
All the storage will be allocated to the VIO servers but can be given to LPARs as required.

D.
Shared Storage pools automatically move data in the background to where it is needed most.

Explanation:
To create a shared storage pool, you group VIOS virtual servers that share physical volumes. A storage pool is
created and shared by all VIOS virtual servers that are members of the shared storage pool
