Which NetApp ONTAP storage efficiency method provides storage savings by placing multiple different 1KB files...

Data compaction reduces physical storage consumption by combining multiple small data chunks into a single physical 4 KB block. ONTAP normally works with 4 KB blocks, meaning that a small object such as a 1 KB file could otherwise consume an entire 4 KB block. Inline data compaction combines such small pieces of data while they are still in memory, allowing several independently addressable data fragments to share one physical block. Compression differs because it reduces data size by encoding data into compression groups, while deduplication eliminates duplicate blocks. Thin provisioning controls capacity allocation rather than block packing. Therefore, when the requirement specifically refers to placing multiple different 1 KB files or data fragments into the same block, compaction is the applicable ONTAP storage-efficiency mechanism.
