QNAP TS-h1655XeU-RP-8G
The QNAP TS-h1655XeU-RP-8G is a short-depth 10GbE ZFS NAS that combines twelve 3.5-inch SATA bays, four E1.S/M.2 PCIe NVMe slots, an Intel® Atom® C5125 8-core processor and redundant power supplies in a compact 3U rackmount chassis.
What is the QNAP TS-h1655XeU-RP-8G?
The TS-h1655XeU-RP-8G is a hybrid-storage rackmount NAS designed for virtualization, backup and data-intensive workloads. It provides twelve SATA drive bays, four E1.S/M.2 PCIe Gen 3 x2 slots, built-in 10GBASE-T and dual 2.5GbE networking, two PCIe Gen 3 x4 slots and redundant 300W power supplies.
Compact 3U Short-Depth Design
High-capacity rackmount storage for installations where rack depth is limited.
With a chassis depth of approximately 29.6cm, the TS-h1655XeU-RP reduces rack depth by 38% while retaining a 3U form factor. Its compact design suits space-constrained server rooms, small business offices, multimedia rooms and security monitoring systems.
The reduced depth also leaves additional room in standard racks for cable organisation or airflow optimisation.
Hybrid Storage and ZFS Data Protection
Flexible SATA and NVMe storage combined with the QuTS hero operating system.
12 SATA Drive Bays
Twelve 3.5-inch SATA bays support 3.5-inch hard drives, 2.5-inch hard drives and 2.5-inch solid state drives.
Four E1.S/M.2 NVMe Slots
Four PCIe Gen 3 x2 slots support E1.S SSDs or M.2 2280 PCIe SSDs through an M.2 adapter, enabling SSD caching and storage acceleration.
QuTS hero
The ZFS-based operating system provides data integrity features including self-healing, WORM, deduplication and SnapSync disaster recovery.
Processor, Memory and Acceleration
Eight-core processing with expandable memory and hardware acceleration.
Intel® Atom® 8-Core Processor
The Intel® Atom® C5125 8-core 2.8GHz processor supports demanding storage, virtualization and data-intensive applications.
Expandable DDR4 Memory
Includes 8GB DDR4 non-ECC memory and supports up to 64GB using two 32GB modules. ECC memory is supported, but ECC and non-ECC memory cannot be mixed.
