Your customer has four disk shelves attached to an HA pair of nodes running clustered Data ONTAP 8.3. One disk shelf has six SSDs and 18 HDDs installed. They
want to know how to partition the SSDs to use them in a flash pool aggregate.
In this situation, what should you tell the customer?

A.
Flash pool aggregates must have whole SSDs assigned, not partitions.

B.
When the disks are assigned to a storage pool, they are automatically partitioned into four equal parts that can be assigned to an existing aggregate where the
partition will be used as flash storage by the assigned aggregate.

C.
All SSDs in a mixed disk system are partitioned to a 25% and a 75% partition. The larger partition can be used for data.

D.
When the disks are assigned to a storage pool, you can partition each disk into as many partitions as needed. A partition can be assigned to an existing
aggregate where the partition will be used as a flash storage by the assigned aggregate.

Explanation:
Advanced drive partitioning for Flash Pool segments each drive into four pieces.
