The NVMe all-flash TS-h2490FU is designed for providing extreme performance with high cost-efficiency. Featuring 24 U.2 NVMe Gen 3 x4 SSD bays, the TS-h2490FU delivers up to 472K/205K random read/write IOPS with ultra-low latency. The ZFS-based QuTS hero operating system supports inline data deduplication and compression for reducing I/O and SSD storage consumption, which significantly extends SSD lifespan with a higher price-performance ratio for all-flash storage arrays. Coupled with near-unlimited snapshots, real-time SnapSync, and petabyte-scale storage expansion capabilities, the TS-h2490FU is ideal for I/O-intensive and latency-sensitive applications, and eliminates productivity bottlenecks in modern data centers, virtualization, and mission-critical backup/restore tasks.

2nd Gen AMD EPYC processors and DDR4 ECC memory
The TS-h2490FU is armed with 2nd Gen AMD EPYC 7002 series processors (Rome). Based on the “Zen 2” architecture with cutting-edge 7nm process technology, up to 128 PCIe lanes of I/O are provided for 32Gb/s dedicated bandwidth per SSD. With DDR4 ECC memory that detects and corrects single-bit memory errors for higher reliability, the TS-h2490FU provides 8-channel modules and 16 Long-DIMM slots to fulfill memory-intensive workloads. Demonstrating immense computing power and multi-tasking capabilities, the TS-h2490FU is the ideal choice for uncompromising performance demands in HPC, virtualization, and hybrid/multi-cloud applications.

U.2 NVMe Gen 3 x4 All-Flash Storage Array
The 2U rackmount TS-h2490FU has 24 drive bays for U.2 NVMe Gen 3 x4 SSDs, with each individual SSD having 32Gb/s dedicated bandwidth for the utmost application response times. Coupled with powerful ZFS data deduction and SSD optimization technologies, the TS-h2490FU provides solid foundations for overcoming complexity and performance demands in today’s evolving data center workloads.

Empower high-speed data transfer with four 25GbE ports
The TS-h2490FU provides breakthrough network connectivity with two pre-installed dual-port 25GbE SFP28 SmartNICs (that use the Broadcom NetXtreme-E Series BCM57414, Mellanox ConnectX-4 Lx, or the same level SmartNIC). With failover and Port Trunking for up to 100Gb/s bandwidth, the TS-h2490FU empowers your organization with the bandwidth to tackle the most demanding applications, including data centers, virtualization, massive file transfer, high-speed backup/restoration, and multimedia transmission.

Multiple PCIe Gen 4 slots for flexible expansion
The TS-h2490FU is equipped with five PCIe Gen 4 slots. With twice the I/O performance of PCIe Gen 3, the TS-h2490FU can take advantage of many PCIe cards to expand application potential.

Robust hardware paralleled to boost all-flash NVMe performance
The TS-h2490FU features high-level hardware with an expandable architecture to provide businesses with high performance and low latency access. With a removable motherboard drawer design, IT staff can easily maintain the TS-h2490FU without needing to remove it from the rack.

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.

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.

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.

All-in-one virtual machine and container hosting solution
You can count on Virtualization Station and Container Station for comprehensive virtualization support. Coupled with the Network & Virtual Switch app that boosts interoperability between virtual machines, containers, QNAP NAS, and other physical devices on the network, you can flexibly allocate physical and virtual network resources to simplify network deployment.

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.

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.
