12-bay rackmount NAS with Xeon D-1726

The Synology RS3626xs is a 2U rackmount network-attached storage server built around a 6-core Intel Xeon D-1726 processor and 16GB of DDR4 ECC memory. It ships fully assembled and tested with twelve 8TB Synology Enterprise NAS drives providing 96TB of raw capacity. The platform targets organisations that need centralised file storage, virtualisation support, and multi-site collaboration in a single appliance.

Thermals noise and power draw

The unit operates from 0°C to 35°C with humidity tolerance of 8% to 80% RH. Dual redundant power supplies accept 100-240 VAC at 50/60Hz and protect service availability from a single power-supply failure. Integrated system fans manage airflow across the twelve drive bays and processor without external liquid cooling. Synology specifies sequential read performance exceeding 6,300 MB/s and write performance exceeding 3,700 MB/s under its test conditions.

Bundled accessories and software impact

The package includes a Synology 2-port 25GbE SFP28 adapter pre-installed in one of two PCIe Gen 4 x8 slots, adding high-speed connectivity beyond the two onboard 10GbE RJ-45 ports and a dedicated out-of-band management LAN port. Two USB 3.2 Gen 1 ports, two C13-to-C14 power cords, a front cover, and an accessory pack complete the physical bundle. DSM software provides the management interface for storage, backup, and surveillance workloads.

Questions about this item

How do I install the Synology 2-Port 25GbE Adapter in the RS3626xs, and what step is often missed?

Insert the adapter into one of the two PCIe Gen 4 x8 slots, secure the bracket screw, then install the driver package from DSM Package Center before configuring the SFP28 ports.

Which components in this RS3626xs will need replacement first under continuous operation?

The twelve 8 TB Synology Enterprise NAS drives and the two redundant power supplies are the primary field-replaceable units; DDR4 ECC memory and the Xeon D-1726 processor are not user-serviceable.

What thermal or power limit appears first when the RS3626xs runs sustained workloads at 35 °C ambient?

The operating-temperature ceiling of 35 °C is the first hard limit; exceeding it triggers protective throttling or shutdown before any power-supply or network-throughput ceiling is reached.
