Question #: 2
Topic #: 2

A company needs to expand their dynamic pool by 10 TB. The current dynamic pool consists of 63 7.6 TB SSD drives that are configured for RAID 5 (12+1).

What is the minimum number of drives needed for the pool expansion?

B15

C13

Show Suggested Answer

Suggested Answer: C

To expand a dynamic pool, the number of drives added must be equal to or greater than the stripe width of the pool. The stripe width is the number of data drives plus the number of parity drives in a RAID group. In this case, the stripe width is 12 + 1 = 13.Therefore, the minimum number of drives needed for the pool expansion is 13.Reference: Dell EMC Unity: Dynamic Pools Technical White Paper1, page 8.
