24-bay EPYC U.2 NVMe all-flash NAS
QNAP TS-h2490FU-7302P-256G
A diskless 2U all-flash rackmount NAS supplied with an AMD EPYC 7302P 16-core processor, 256GB ECC DDR4, twenty-four 2.5-inch U.2 NVMe bays, four 25GbE SFP28 ports and two 2.5GbE ports. The title and technical table conflict on the number of U.2 bays.
High-throughput U.2 NVMe storage with four 25GbE ports
The QNAP TS-h2490FU-7302P-256G is presented as a 24-bay U.2 NVMe all-flash NAS with an AMD EPYC processor, 256GB ECC DDR4 and four 25GbE SFP28 ports. The opening and specification table both state twenty-four U.2 bays, while the product title ends with “4 × 2.5-inch U.2 PCIe NVMe”; that source conflict must be confirmed before publishing.
Key features and benefits
EPYC and ECC platform
The sixteen-core AMD EPYC 7302P is paired with 256GB ECC DDR4 and a listed maximum of 4TB.
U.2 NVMe all-flash design
The opening and technical table list twenty-four U.2 NVMe Gen 3 x4 SSD bays; the title lists four and needs confirmation.
Four 25GbE SFP28 ports
Four preinstalled 25GbE SFP28 SmartNIC ports and two 2.5GbE ports are supplied.
Five PCIe Gen 4 slots
Five slots support the supplied networking, QM2 and Fibre Channel adapter categories, subject to the listed lane-sharing notes.
SSD-focused data services
The source includes inline deduplication and compression, pool over-provisioning and TRIM.
Virtualisation and expansion
The supplied content positions the system for virtualisation, intensive file access, backup and SAS expansion.
Who is the QNAP TS-h2490FU-7302P-256G best for?
A strong choice for
- I/O-intensive and latency-sensitive storage
- Virtualisation and modern data-centre workloads
- Large backup and restoration tasks
- High-throughput 25GbE environments
- Dense U.2 NVMe all-flash deployments after confirming bay count
Consider another model if you need
- Publishing before confirming the four-versus-twenty-four U.2 bay conflict
- A SATA SSD or HDD storage platform
- A tower enclosure
- A system supplied with SSDs
- Lower network-speed requirements that do not need four 25GbE ports
