NetApp Certified Design Engineer – SAN — Question 18

You have a 4-node cluster with an AFF A300 HA pair and a FAS8200 HA pair. You plan on using the default storage efficiency settings. With inline data compaction, you estimate that you can save 6% of storage space. AFF A300 LUNs that use under 5000 IOPS are moved to a FAS8200 using the lun move command.
In this scenario, what happens to the data after the LUN is moved? (Choose two.)

Answer options

• A. The new written data is not compacted.
• B. The new written data is compacted.
• C. The existing data is compacted.
• D. The existing data is not compacted.

Correct answer: B, D

Explanation

After the LUN is moved, any new data written to the FAS8200 will be compacted, as indicated in option B. However, the existing data that was moved from the AFF A300 will not undergo compaction on the FAS8200, as stated in option D, since it retains the characteristics it had on the original AFF A300.
