Question Image

You are investigating high CPU utilization on a FAS8200 that uses only SAS HDDs. SAN hosts have LUNs in a volume called vol1. You need to reduce CPU utilization while retaining storage efficiencies.

With reference to the exhibit, which three actions accomplish this task?

Choose three
  • A Disable compression.
  • B Enable cross-volume deduplication.
  • C Disable inline deduplication.
  • D Enable post process deduplication.
  • E Enable data compaction.
Explanation

Inline compression and inline deduplication perform storage-efficiency work in the write path and consume controller CPU. Disabling compression and inline deduplication reduces that immediate CPU load. Enabling postprocess deduplication preserves deduplication-based space savings by running deduplication after data is written. Cross-volume deduplication is unnecessary for the single volume, and enabling inline data compaction on an HDD aggregate uses additional CPU resources.
