Enterprise 12-Bay Rackmount NAS

The Synology RS3626xs is a 2U rackmount NAS with twelve drive bays, built for organisations that need centralised file storage, virtualization support and multi-site collaboration. It ships fully assembled with a 6-core Intel Xeon D-1726 processor, 32GB of DDR4 ECC memory, 1.6TB of enterprise SSD cache and 144TB of Synology enterprise hard drives pre-installed.

Thermals and power

The unit operates between 0°C and 35°C with redundant power supplies that accept 100-240 VAC at 50/60Hz, protecting service availability if one supply fails. Dual 10GbE RJ-45 ports and an out-of-band management port handle network traffic while the chassis dimensions of 88 mm × 482 mm × 724 mm fit standard racks.

Bundled drives and cache

Twelve 12TB enterprise NAS drives and two 800GB enterprise SSDs are installed and tested, delivering the full 144TB raw capacity and 1.6TB read-write cache immediately. Two PCIe Gen 4 x8 slots remain free for future 10GbE, 25GbE or Fibre Channel adapters, and two USB 3.2 Gen 1 ports provide direct peripheral connectivity.

Questions about this item

How do I install the 12 x 12TB Synology Enterprise drives into the RS3626xs, and what step is often missed?

Slide each 3.5-inch drive into a front bay until the latch clicks; the step often missed is confirming the storage pool is created in DSM before writing data.

What maintenance or replacement will the 1.6TB Synology Enterprise cache need later?

The 2 x 800GB cache modules are installed in PCIe Gen 4 x8 slots; monitor SSD health in DSM and replace a module when its endurance indicator reaches the warning threshold.

What thermal limit appears first when the Xeon D-1726 runs sustained workloads in a 35°C rack?

The operating ceiling is 35°C; sustained loads can push internal temperatures past this limit before the CPU throttles, so maintain front-to-rear airflow and clean filters regularly.
