Enterprise Rackmount NAS for Business Workloads

The Synology RS3626xs is a 2U 12-bay rackmount NAS powered by a 6-core Intel Xeon D-1726 processor with 8GB of DDR4 ECC memory. It ships fully assembled and tested with twelve 20TB Synology Enterprise drives providing 240TB of raw capacity. Designed for centralised file storage, virtualisation and surveillance workloads.

Suited for Growing Organisations Needing Redundant

This unit fits IT teams that require high-capacity shared storage with dual 10GbE ports for link aggregation and failover. Redundant power supplies protect uptime from a single supply failure. PCIe Gen 4 x8 slots allow future network or caching upgrades. Buyers needing only a few terabytes or lacking rack infrastructure should consider smaller desktop alternatives.

Integrates into Standard Racks

The chassis measures 88mm high, 482mm wide and 724mm deep, weighing 14.5kg with drives installed. It operates on 100-240 VAC power within a 0°C to 35°C range. Two PCIe Gen 4 x8 slots free up I/O lanes for 10GbE, 25GbE or Fibre Channel adapters. Memory can be expanded to 48GB to support heavier virtualisation workloads.

Questions about this item

Does the RS3626xs require separate drives or are the 20 TB SATA drives already installed?

Twelve 20 TB Synology Enterprise SATA drives are pre-installed, providing 240 TB of raw capacity out of the box.

Can I connect the two 10GbE RJ-45 ports to my existing gigabit switches?

Yes, the 10GbE ports auto-negotiate down to 1 GbE, so they work with current gigabit infrastructure.

How can I verify the NAS is delivering the reported 6 300 MB/s read and 3 700 MB/s write speeds?

Run a sequential throughput test from a client over the 10GbE link and compare results to Synology's published figures.
