Compact 3U short-depth rackmount design

The chassis measures 133 × 432.4 × 297mm, providing a short-depth 3U form factor for installations with limited rack space.

The supplied description rounds the depth to approximately 29.6cm, while the detailed specification lists 297mm.

Net weight is listed as 10.77kg.
Three 80mm system fans are included.
The source positions the design for space-constrained server rooms, offices, multimedia rooms and monitoring systems.

Twelve SATA bays plus four E1.S/M.2 NVMe slots

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 PCIe Gen 3 x2 slots support E1.S SSDs or M.2 2280 PCIe SSDs through compatible M.2 adapters.

The system is supplied without hard drives.
The drive bays are listed as hot-swappable.
SSD cache acceleration is supported.

Intel Atom processing and expandable DDR4 memory

The Intel Atom C5125 provides eight cores at 2.8GHz for storage, virtualisation and data-intensive applications.

This configuration includes 8GB non-ECC SODIMM DDR4 memory and supports up to 64GB using two 32GB modules.

The memory slots support ECC memory, but ECC and non-ECC modules cannot be mixed.
AES-NI hardware encryption support is listed.
The supplied description identifies Intel QAT acceleration for compression and encryption workloads.

Built-in 10GbE, dual 2.5GbE and PCIe expansion

One 10GBASE-T port and two 2.5GbE ports provide built-in multi-gigabit networking. Optional 5GbE and 25GbE are supported through compatible adapters.

Two PCIe Gen 3 x4 slots support compatible network adapters, QM2 cards or Fibre Channel cards.

Wake on LAN is supported through the 2.5GbE ports only.
SR-IOV and Jumbo Frame support are listed.
An HDMI output is optional through a compatible PCIe graphics card.

QuTS hero protection and redundant operation

The supplied QuTS hero feature set includes self-healing, WORM, deduplication and SnapSync disaster recovery.

Two minimum 300W power supply units are listed for redundant operation.

The supplied product information lists VMware and Hyper-V virtualisation workloads.
Typical operating power is listed as 121.7W when fully populated with the specified test drives.
The supplied award reference applies to QuTS hero rather than the exact NAS.

Important purchasing and deployment notes

This system is supplied without hard drives; compatible SATA, E1.S or M.2 storage must be purchased separately.
M.2 2280 SSD support through the E1.S slots requires compatible adapters.
ECC and non-ECC memory modules cannot be mixed, and dual-DIMM configurations should use matching modules.
Confirm drive, adapter, network, PCIe card and rack compatibility before deployment.
