Purpose-built controller

This Qnap CTL-ES1686DC-2123IT-32G is a new rackmount NAS controller FRU designed for the ES1686dc chassis. It delivers an Intel Xeon D-2123IT 4-core processor running at 2.20 GHz with burst up to 3.0 GHz and 32 GB of installed memory across eight slots. The unit supports 16 SAS drive bays for 3.5-inch or 2.5-inch SAS/SATA hard disks and SSDs, scaling to a maximum raw capacity of 352 TB. It targets environments that need ultra-high performance for a large number of concurrent users.

Thermals and power

Redundant hot-swap power supplies accept 90 to 264 VAC input and are rated at 770 W, with typical operating draw measured at 500.87 W. The controller is specified for continuous operation between 0 and 40 °C and can be stored from -20 to 70 °C. Humidity tolerance spans 5 to 95 % RH non-condensing with a wet-bulb limit of 27 °C. No power supply or battery backup unit is included with this FRU.

Build integration

The controller occupies a 16-bay form factor measuring 132 by 483.05 by 630.62 mm and weighs 25.83 kg net. It requires a compatible ES1686dc chassis, separate power supply modules and a battery backup unit to become operational. Eight memory slots allow expansion up to 512 GB for workloads that outgrow the factory 32 GB. Builders who need integrated power supplies or a populated drive set should look elsewhere.

Questions sur cet article

How do I install the Intel Xeon D-2123IT controller into the 16-bay SAS chassis, and what step is often missed?

Slide the controller module into the dedicated slot until the latch clicks, then seat all 16 SAS drive trays; the step often missed is verifying both redundant 770 W power supplies are fully engaged before powering on.

Which components will need replacement first during long-term operation of this 32 GB system?

The hot-swap SAS drives and the dual 770 W power supplies are the primary field-replaceable units; memory can be expanded later using the eight DIMM slots up to 512 GB.

What thermal limit appears first when the dual-controller NAS runs sustained workloads at 500.87 W typical draw?

The operating temperature ceiling of 40 °C is the first limit reached; airflow must keep the 132 mm-high enclosure within the 5–95 % RH non-condensing range to avoid throttling.
