Ready-to-Run 12-Bay Rackmount NAS

The Synology RS3626xs arrives fully assembled with 48GB of DDR4 memory and a 2-port 25GbE adapter installed. Twelve 12TB Synology Enterprise drives provide 144TB of raw capacity out of the box. A 6-core Intel Xeon D-1726 processor handles demanding business workloads including virtualization and multi-site collaboration. Redundant power supplies protect service availability from a single power-supply failure.

Suited For Centralised File Storage

Organisations that need high-capacity storage with integrated 10GbE and optional 25GbE connectivity will benefit from the two RJ-45 ports and the pre-installed SFP28 adapter. Two PCIe Gen 4 x8 slots allow further expansion for networking or SSD caching as requirements grow. Buyers who require Fibre Channel connectivity should verify adapter compatibility before purchase. The operating range of 0°C to 35°C limits deployment to controlled environments.

144TB Raw Capacity With Twelve Enterprise Drives

The included drive set delivers 144TB across twelve bays using 3.5-inch SATA HDDs. Sequential read performance exceeds 6300 MB/s and write exceeds 3700 MB/s under vendor test conditions. Link aggregation on the dual 10GbE ports increases bandwidth and provides network failover. The 2U chassis measures 88 mm × 482 mm × 724 mm and weighs 14.5 kg.

Questions about this item

What rack depth and power cords do I need to install this 2U 12-bay unit?

The chassis measures 88 mm high, 482 mm wide and 724 mm deep and ships with two C13-to-C14 power cords for redundant 100-240 VAC supplies.

Can I keep using my existing 10GbE RJ-45 switches with the two onboard 10GbE ports and the add-in 25GbE adapter?

Yes, the two integrated 10GbE RJ-45 ports work with your current switches, while the included dual-port 25GbE SFP28 adapter adds separate 25 Gb/s uplinks.

How do I confirm the 48 GB of DDR4 ECC memory and all twelve 12 TB drives are recognised after first boot?

Log into the web-based DSM interface; the System Information page shows 48 GB DDR4 ECC RAM and Storage Manager lists twelve 12 TB SATA volumes totalling 144 TB.
