QuTS hero 5.1 highlights
Enable SMB multichannel for full throughput and multi-path protection
SMB multichannel aggregates multiple network connections to maximize available bandwidth with higher transfer speeds – especially ideal for transferring large files and multimedia. If one connection fails, application I/O continues with the remaining network. Total bandwidth automatically reverts to full throughput once the failure recovers. Learn more
Secure login with two-factor authentication (2FA)
Apply a two-step log-in process to your NAS accounts to help prevent unauthorized access to your NAS and to ensure NAS data and network security. Install the QNAP Authenticator app on your mobile device, set up 2-Step verification, and log in your NAS securely and conveniently. Learn more
Delegated administration boosts management productivity and ensure data security
NAS administrators can delegate eight types of roles to other users with specific permissions to manage tasks and NAS data. For growing organizations, role delegation helps ease management workloads. Learn more
Expand ZFS RAID-Z capacity by adding a single disk
Expanding the capacity of a ZFS RAID-Z previously required adding another RAID group. Now, you can simply add a single disk to an existing RAID-Z for storage expansion, or conveniently add 2 to 3 disks for upgrading RAID level with Parity.
Improved iSCSI read performance by socket zero-copy
In high-speed data transmission, iSCSI performance is possibly affected by CPU overhead. QuTS hero 5.1 supports socket zero-copy technology that significantly offloads CPU resources, thus improving read performance for iSCSI LUN.
iSCSI Read Performance (25GbE x5)

-
Up to 5 petabytes capacity per shared folder
QuTS hero NAS supports up to 5 PB capacity for individual shared folders, enabling enterprises to tackle storage-demanding applications including Big Data analysis, edge computing, and AI.
-
Dedicated ZIL - SLOG
By storing the ZIL and read cache (L2 ARC) data on different SSDs for processing read and write workloads separately, you can benefit from better overall system performance and improved SSD utilization and lifespan, ensuring that your flash storage investments are fully optimized.
-
Increased security level
Supports TLS 1.3 to improve security and performance, auto-update of the operating system and apps to ensure your NAS operates under optimal conditions, and SSH keys for authentication that help secure access to your NAS, preventing password breaches or similar potential attacks.
-
Instant Clone
After synchronizing data via SnapSync from a primary to a secondary NAS, you can further conduct Snapshot Instant Clone on the secondary NAS. This assists in copy data management and data analysis without interfering with production server operations and the primary data. Instant Clone is also useful for DevOps, such as app development, database testing, analysis, and reporting.
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.
-
Inline Compression
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.
-
Inline Compaction
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 65,536 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.
1. SnapSync is supported by QNAP NAS models featuring the QuTS hero (4.5 or later) and QES ( v2.1.1 v11 or later) operating systems. These NAS can be paired with each other to provide the perfect backup storage solution.
2. To ensure successful synchronization of folder & file permission settings, it is strongly recommended that the SnapSync-paired NAS systems are deployed in an AD/LDAP compliant domain environment to prevent inconsistent system UIDs (especially when the paired NAS includes a QuTS hero NAS and a QES NAS).
Prevent simultaneous multi-SSD failures with QSAL
SSD lifespan is determined by a finite number of writes. It is highly possible that several SSDs in the same RAID reach their end-of-life at the same time, causing a RAID crash with data loss. QNAP’s patented QSAL (QNAP SSD Antiwear Leveling) algorithm regularly detects the lifespan and durability of SSD RAID. When SSD lifespan is in its final 50%, QSAL will dynamically distribute the over-provisioning space to guarantee each SSD has enough time to rebuild before it reaches end of life. This can effectively prevent simultaneous multi-SSD failures and improves the reliability of the entire system. QSAL has little effect on storage space utilization, only causes a negligible decrease in performance, and significantly improves overall data protection for flash storage.
QSAL can be activated at any time and is compatible with SSD Parity RAID that has not been configured before. It is recommended to enable QSAL before the SSD lifespan reaches 50% to prevent the risk of damage to the SSD RAID due to insufficient rebuild time.
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.
AES-NI acceleration for SMB 3 signing and encryption
For business applications that demand high-level security, SMB signing and encryption options help enhance file sharing security over the network, but can also negatively impact data transmission performance. QuTS hero NAS supports AES-NI hardware acceleration to increase data signing and encryption/decryption efficiency over SMB 3, boosting system performance while securing sensitive business data.

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.
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.
