12-Bay Rackmount NAS for Enterprise Workloads

The Synology RS3626xs is a 2U rackmount network-attached storage system built for demanding business environments. It ships with an Intel Xeon D-1726 processor, 48GB of DDR4 ECC memory, and twelve pre-installed 12TB Synology Enterprise drives providing 144TB of raw capacity. The unit includes a Synology 2-Port 10GbE adapter for high-speed network connectivity out of the box.

Verify Rack Space, Power, and Network Infrastructure

Confirm your rack can accommodate a 2U unit measuring 88 mm high, 482 mm wide, and 724 mm deep with a weight of 14.5 kg. The system requires two C13 to C14 power cords connected to 100-240 VAC 50/60Hz sources for redundant power supply operation. Ensure your network switches support 10GBASE-T RJ-45 connections to utilise the integrated and adapter 10GbE ports, and plan for the out-of-band management LAN port.

Pre-Installed Drives and 10GbE Adapter Accelerate

The twelve Synology Enterprise NAS drives arrive installed and configured within the chassis, eliminating drive mounting and initial volume creation steps. The included Synology 2-Port 10GbE adapter occupies one PCIe Gen 4 x8 slot, adding two additional 10GBASE-T ports for link aggregation or network segmentation. Two USB 3.2 Gen 1 ports remain available for external backup targets or license dongles, while a second PCIe slot stays open for future expansion cards.

Questions about this item

What drives and accessories come pre-installed in the RS3626xs?

The unit ships with twelve 12 TB Synology Enterprise NAS drives installed, providing 144 TB total capacity, plus 48 GB of DDR4 ECC memory and a Synology 2-Port 10GbE Adapter already fitted.

How does the 48 GB memory configuration differ from the base specification?

The base RS3626xs includes 8 GB of DDR4 ECC memory; this build expands it to the maximum 48 GB using Synology DDR4 modules for heavier virtualization and multi-user workloads.

What real-world throughput can I expect from the dual 10GbE ports?

Synology reports sequential performance exceeding 6,300 MB/s read and 3,700 MB/s write under its test conditions when the two integrated 10GbE RJ-45 ports are used with Link Aggregation.
