ZFS-based QuTS hero ensures performance and data integrity
Faced with the explosive growth of data, VDI popularity, increasing SSD adoption, 8K media, and other disruptive IT trends, modern businesses need dependable storage systems to meet future demands. QNAP’s new “QuTS hero” operating system combines the app-based QTS with a 128-bit ZFS file system to provide flexible storage management, comprehensive data protection and optimized performance to meet the needs of business-critical applications.

Empower your business - Upgrade to QuTS hero now!
Improve your storage performance with inline data deduplication, compression, and compaction
Inline Data Deduplication
Inline deduplication is block-based and is carried out before data is written to storage. This greatly optimizes storage usage while significantly decreasing storage capacity requirements.
Compress data to reduce storage I/O workloads for improved performance. In VDI, deduplicated virtual desktops are easily cached to achieve optimal virtual desktop performance.
Especially helpful for increasing SSD storage efficiency when highly-repetitive data or massive small files (e.g. transaction logs of banks or e-commerce) are generated. It delivers higher cost efficiency for all-flash storage systems.
Self-Healing ensures data integrity and reliability
Data integrity is key to the reliability of applications and databases. As SSD adoption grows, businesses will encounter a greater risk of data loss as it is difficult to recover data from a dead SSD. Designed with a focus on data integrity, ZFS uses end-to-end checksums to detect and correct silent data corruption caused by hardware defects, bugs in firmware or metadata errors. If an integrity violation is detected, ZFS automatically repairs the damage using data from another mirror before the data is passed to applications. QuTS hero is also WORM (Write Once, Read Many Times) compliant to ensure that data, once written, cannot be modified.
Robust data protection and flexible capacity utilization with RAID Z
QuTS hero supports conventional RAID configurations (RAID 0 (Striped), RAID 1 (Mirror), RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60) and adds support of RAID Triple Parity for protecting against three-disk failures and Triple Mirror for an identical copy of data stored on three disks. Designed to deal with petabytes of data, RAID Z demonstrates an outstanding tool for creating ready-to-use high-capacity RAID in a matter of seconds.
Multi-level cache technology with both read and write boosts performance
ZFS simultaneously supports main memory read cache (L1 ARC), SSD second-level read cache (L2 ARC), and ZFS Intent Log (ZIL) for synchronous transactions. The L1 ARC works with the L2 ARC to minimize hard drive access requirements while boosting read performance. The ZIL is useful for applications with large synchronous random write workloads (such as databases), as data will be written to the ZIL first and then written to storage, helping to decrease latency and improve write performance.
Snapshots multiply backup protection
Near-limitless, instant snapshots bring you peace of mind
Supports up to 65,535 snapshots for iSCSI LUN and shared folders (if 1 snapshot is created every hour, 24 snapshots per day, then up to 7 years of snapshots can be created without needing to delete any!). Copy-on-write technology makes snapshot creation almost instantaneous without affecting ongoing data writing.
Snapshot Replica simplifies data protection
Efficiently replicates snapshots to a remote server by copying only the changes made. This can save time and bandwidth, and can be run manually or on a scheduled basis.
SnapSync for remote snapshot replication enables enterprise-class disaster recovery
Supports block-level SnapSync for remote snapshot backups. It only transfers changed data to save required storage space and to improve backup speeds. Real-time SnapSync ensures that when a change is made to the files in the target storage space, a remote replication will be processed. In the event of a primary site failure, SnapSync assists businesses to resume essential services in the shortest time.
(SnapSync will be available from Q3 2020)
Pool over-provisioning ensures write performance
With Pool Over-provisioning, space can be flexibly reserved in a storage pool to allow new data to be written into a complete block even if the pool is almost full, thus improving the performance of fragmented pools. For write-intensive workloads and performance-demanding applications (such as SQL transaction logs, backups, surveillance, and medical videos) you can set higher pool over-provisioning to attain higher write performance.

When small blocks are written to SSD
About NAS migration and RAID management for QuTS hero
As ZFS metadata management is different from Ext4, QTS-based NAS drives cannot be directly used by a QuTS hero-based NAS (and vice versa). Users can install new hard drives to start QuTS hero. If QTS users want to use their existing drives in QuTS hero, they must first ensure all of their drive data has been backed up, and then initialize the hard drives. It is recommended that users thoroughly evaluate their storage needs before installing QuTS hero.
Expanding the storage capacity of a QuTS hero NAS requires adding a complete RAID group to the Storage Pool. Once a RAID group is created, it does not support expanding a RAID group by adding an individual hard drive and does not support migrating RAID levels. Users can allocate spare hard drives for Hot Spare protection or creating additional RAID groups. Users must have enough drive bays to facilitate storage expansion needs in the future when configuring storage in different stages.
