Compaction Compaction reduces the amount of physical storage required for a volume by taking data chunks that are stored in 4 KB blocks, but that are less than 4 KB in size, and combining them into a single block. Compaction takes place while data is still in memory so unnecessary space is never consumed on disks. It is enabled by default on AFF and ASA systems. You need to manually enable compaction on FAS systems. https://docs.netapp.com/us-en/ontap/concepts/storage-efficiency-overview.html
