ZFS-based QuTS hero operating system enhances NAS performance and data integrity
QuTS hero combines the app-based QTS with the 128-bit ZFS file system to provide flexible storage management, comprehensive data protection, and optimized performance to tackle the complexity and performance demands of modern IT. From storage management, virtualization, to collaborative media workflows, QuTS hero streamlines your business-critical tasks.
Data integrity is key
QuTS hero’s self-healing ensures data integrity and reliability. Write Once, Read Many (WORM) is also supported.
Data reduction improves storage efficiency and performance
Inline data deduplication, compression, and compaction reduce file sizes to conserve storage capacity and optimize performance.
Multi-level cache technology
Main memory read cache (L1 ARC), SSD second-level read cache (L2 ARC), and ZFS Intent Log (ZIL) for synchronous transactions with power failure protection are supported to boost performance and security.
RAID Z enables robust data protection
Multiple RAID levels allow flexible capacity utilization. RAID Triple Parity and Triple Mirror deliver higher levels of data protection.
QSAL (QNAP SSD Antiwear Leveling) enhances data protection
RAID-level SSD lifespan is automatically and regularly detected to prevent simultaneous SSD failure, improving your data protection and system reliability.
App Center ecosystem extends NAS functionality
Apps for backup/sync, virtual machines/containers, content management, productivity, and more features can be used to expand the application potential of the NAS.
Inline data deduplication, compression, and compaction improve SSD endurance
QuTS hero supports advanced block-based data reduction technologies (including inline data deduplication, compression, and compaction) to reduce file sizes, conserve storage capacity, and optimize performance. For example, if 20 virtual machines on a NAS are replicated using the same template, then storage space requirements for all 20 virtual machines can be reduced by up to 95%. Whether acting as primary or backup storage, the TVS-h874 optimizes storage utilization to provide a reliable storage cornerstone in the Big Data era. All-flash solutions thus achieve higher cost efficiency while improving both random write performance and SSD lifespan.
Inline Data Deduplication requires a NAS with at least 16GB memory (at least 32GB memory is recommended for optimal performance).
