24-bay U.2 NVMe all-flash NAS
AMD EPYC™ 7002 series processor
Up to 661K / 245K iSCSI 4K random read/write IOPS
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.
-
Optimal SSD performance
Inline data deduplication and compression, Pool Over-provisioning, and TRIM maximize SSD performance and lifespan.
-
4 x 25GbE SFP28 ports
Multi-connectivity of 25GbE SFP28 and 2.5GbE RJ45 accelerate virtualization, intensive file access, and large backup/restoration tasks.
-
5 x PCIe Gen 4 slots
PCIe Gen 4 slots allow for installing 10GbE/25GbE/40GbE/100GbE adapters, QM2 cards, or Fibre Channel cards to increase application performance.
-
Virtualization applications
Supports virtualization storage and hosting virtual machines and containerized apps.
-
Cloud storage gateway
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.
-
Petabyte-scale storage
Scalable design to grow with your business by connecting SAS 12Gb/s expansion enclosures for up to petabyte-scale storage capacity.
