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 661K / 245K 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.
Inline data deduplication and compression, Pool Over-provisioning, and TRIM maximize SSD performance and lifespan.
Multi-connectivity of 25GbE SFP28 and 2.5GbE RJ45 accelerate virtualization, intensive file access, and large backup/restoration tasks.
PCIe Gen 4 slots allow for installing 10GbE/25GbE/40GbE/100GbE adapters, QM2 cards, or Fibre Channel cards to increase application performance.
Supports virtualization storage and hosting virtual machines and containerized apps.
Cloud storage gateways realize hybrid cloud applications by working with the cache space reserved on NAS to ensure low-latency data access to the cloud.
Scalable design to grow with your business by connecting SAS 12Gb/s expansion enclosures for up to petabyte-scale storage capacity.
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.
