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 | Data reduction improves storage efficiency and performance | Multi-level cache technology with both read and write |
---|---|---|
QuTS hero's self-healing ensures data integrity and reliability. Write Once, Read Many Times (WORM) is also supported. | Inline data deduplication, compression, and compaction reduce file size to conserve storage capacity and optimize performance. | Main memory read cache (L1 ARC), SSD second-level read cache (L2 ARC), and ZFS Intent Log (ZIL) for synchronous transactions with power fail protection are simultaneously supported to boost performance and security. |
RAID Z enables robust data protection | QSAL (QNAP SSD Antiwear Leveling) enhances data protection | App Center ecosystem extends NAS functionality |
Multiple RAID levels allow flexible capacity utilization. RAID Triple Parity and Triple Mirror deliver higher levels of data protection. | RAID-level SSD lifespan is automatically and regularly detected to prevent simultaneous SSD failure, improving your data protection and system reliability/ | Apps for backup/sync, virtual machines/containers, content management, productivity, and more features can be used to expand the application potential of the TS-h2490FU. |
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 TS-h2490FU 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.
More SSD performance and lifespan optimization technologies
Write Coalescing
Transforms all random writes to sequential writes along with reduced I/O, effectively increasing write performance in all-flash environments.
Pool Over-provisioning
Dedicated space can be flexibly reserved in an SSD 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.
TRIM
Allows QuTS hero to inform SSDs to delete unneeded data blocks and process the deletion tasks during system idle times, meaning it does not have to wait for when new data is written to the block.
Real-time SnapSync ensures minimal RPO with real-time disaster recovery
Real-time SnapSync ensures that both the primary and secondary NAS maintain identical data. When data is written to the source, it is immediately written to the destination. If the primary NAS goes offline, IT staff can simply adjust the privilege settings of the secondary NAS to ensure continuous operations. SnapSync provides the strongest support for nonstop business operations and helps users to reduce the risk of data loss.
The TS-h2490FU also supports snapshots and remote backup to help organizations accomplish routine backup tasks cost-effectively and efficiently.
Snapshots multiply backup protection
Attain peace of mind with near-limitless, instant snapshots. Copy-on-write technology makes snapshot creation almost instantaneous without affecting ongoing data writing. Snapshot Replica replicates snapshot files to the backup NAS, simplifying data protection with version control.
HBS simplifies 3-2-1 backup plans
HBS centralizes backup, restoration, and synchronization for easily transferring data in the TS-h2490FU to another QNAP NAS, remote server, or cloud storage space. HBS supports QuDedup technology that eliminates redundant data at the source and makes multi-version backup faster.
High availability (HA) and failover with dual-NAS architecture
Create a HA cluster with two TS-h2490FU — one as the active server, and the other as the passive server. If an unexpected failure or issue with the active server occurs, the passive server provides immediate protection with automatic failover. This ensures continuous storage service and system availability.
Easy management and monitoring
Use the High Availability Manager app to easily configure, remove, or rebuild clusters.
Guaranteed data consistency
Real-time data sync between active and passive servers minimizes the risk of data loss (RPO).
Ensured continuity of critical business
The passive server takes over within 1 minute if the active server fails (RTO < 60 secs).
Run VMs and Containers
With no additional fees, you can run multiple VMs of different OS on TS-h2490FU. This allows you to deploy multi-tenant environments and applications to increase management efficiency and save hardware costs.
VMs
Securely run Windows®, Linux®, UNIX®, QuTScloud VMs using Virtualization Station.
Containers
Run Docker®, LXD, Kata Containers and download Container Apps using Container Station.
VM High Availability (Coming soon)
VM Live Migration and HA (High Availability) guarantee continuous operation and minimal downtime.
Network & Virtual Switch
Flexibly allocate virtual network resources and configure VLANs to ensure virtual services via the virtual network topology in Network & Virtual Switch.
Single Root I/O Virtualization (SR-IOV)
By installing an SR-IOV compatible PCIe SmartNIC in the TS-h2490FU, you can allocate bandwidth resources from a physical network card directly to VMs. With traffic bypassing the Hypervisor vSwitch, it helps enhance I/O throughout and network efficiency, ensuring reliable VM applications and reduced CPU overheads.
License-free VMware® and Hyper-V backup appliance
With Hyper Data Protector, the TS-h2490FU becomes an agentless backup tool for unlimited VMware® vSphere and Microsoft® Hyper-V VM backup. Hyper Data Protector features incremental backup, global deduplication, backup scheduling and recovery compression. Hyper Data Protector also simultaneously backs up multiple VMs, providing you with a cost-effective and reliable disaster recovery plan, ensuring 24/7 operation of your services.
Move business data to the cloud and enjoy low latency access to cloud-based data
The TS-h2490FU perfectly integrates NAS with mainstream cloud services. By deploying cloud storage gateways and enabling local caching, organizations can seamlessly use the cloud for storage, backup, and data recovery with low-latency access. This greatly helps in realizing cost-effective, flexible and secure hybrid cloud applications.

HybridMount File-Based Cloud Gateway
Flexibly expand storage capacity by connecting to cloud storage. You can leverage QuTS hero apps to manage and edit your cloud files or multimedia files. HybridMount is ideal for file server online collaboration and file-level data analysis.

VJBOD Cloud block-based cloud gateway
VJBOD Cloud supports streamlined NAS backup to object cloud storage. The block-based data transmission uploads random data and large files to the cloud in blocks, and only transmits block-based volume or LUN changes (such as addition, modification, or deletion). This is ideal for enterprise-level applications with large file transfer requirements, such as databases, VM volumes, and videos.
High-performance, reliable storage solution for virtualization
- Supports block-based iSCSI LUN as a high-performance, reliable, and affordable storage solution for VMware®, Microsoft® Hyper-V®, and Windows Server® 2019 virtualization environments.
- Supports VMware VAAI and Microsoft ODX to increase performance by offloading server loading for ESXi server and Hyper-V respectively, and supports QNAP vSphere Client plug-in with enhanced operational efficiency and management in virtualization applications.
Build an affordable Fibre Channel SAN environment
Common Fibre Channel Storage Area Networks (SAN) devices are often costly. By installing QNAP dual-port 16Gb/32Gb Fibre Channel expansion cards in the TS-h2490FU, you have more budget-friendly options to add a NAS to a SAN environment. You can set a Fibre Channel Target using the iSCSI & Fibre Channel app. Moreover, the LUN Masking and Port Binding features provide an additional layer of data security.
