What is the maximum size of a drive partnership group when expanding a Dynamic Pool?

The question contains a common point of confusion between Dynamic Pools and Traditional Pools. For Dynamic Pools, the underlying structures are Drive Partnership Groups (DPGs), and the maximum width (size) of a single DPG is 16 drives (e.g., 14+2 for RAID 6). However, for Traditional Pools, the maximum number of drives in a RAID 6 group is 32. Given the options, the question is likely flawed and incorrectly refers to a Dynamic Pool when intending to ask about the limit for a Traditional Pool's RAID 6 group.

A. 64 drives: This number does not correspond to a maximum RAID group or partnership group size for either Traditional or Dynamic pools on Dell Unity XT.
B. 84 drives: This is not a valid maximum group size for any pool or RAID type on the Dell Unity XT platform.
C. 96 drives: This is not a valid maximum group size for any pool or RAID type on the Dell Unity XT platform.

Page 11: "For traditional pools

the maximum number of drives in a RAID 5 private RAID group is 16

and the maximum for a RAID 6 private RAID group is 32."

with the maximum being 16 drives for a 14+2 RAID 6 configuration.
