Dell EMC Specialist – Implementation Engineer, PS Series — Question 18

When installing an SC Series array, the customer indicated that they want the controller configured to provide the maximum amount of storage space. You discover that the storage controller was shipped with twelve 900 GB drives and twelve 1.8 TB drives of the same type.
Which redundancy level can be selected to provide the maximum amount of storage?

Answer options

• A. Put equal size drives in their own pagepool. Change the default redundancy level for the 1.8 TB drives.
• B. Put all drives in the same tier. Keep the default redundancy level for both the 900 GB and 1.8 TB drives.
• C. Put equal size drives in their own tier. Change the default redundancy level for the 900 GB drives.
• D. Put equal size drives in their own pagepool. Keep the default redundancy level for both the 900 GB and 1.8 TB drives.

Correct answer: C

Explanation

Choosing option C allows the 900 GB drives to be configured separately, enabling the adjustment of the redundancy level to optimize the overall storage capacity. Options A and D do not maximize the storage because they keep the default redundancy levels for larger drives while isolating the smaller drives. Option B limits the storage efficiency by maintaining the same redundancy level for both sizes without taking advantage of the larger drives' capacity.
