How does Inline Compaction work in QuTS hero?
Applied Products:
-
The NAS runs QuTS hero
In addition to the two ZFS data reduction technologies,
- Inline Compression
- Inline Data Deduplication
QNAP also added "Inline Compaction" to QuTS hero.
The Data Compaction technology is used to further reduce the data and save storage space. When data is written, the system will compress the data first, and then store it in the disk.
Knowing that after data compression, the entire block space (usually 4 KB) is often not used up, the "online data compaction" technology can merge the small data to the same block, this will reduce the number of used blocks to pack as much data as possible, which improves the space utilization.
After the "Inline Compaction" step is completed, the "Inline Data Deduplication" will be executed again to achieve the best storage efficiency.
