Enterprise 12-Bay Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for business workloads. It ships fully assembled with twelve 12TB Synology Enterprise drives providing 144TB of raw capacity. A 6-core Intel Xeon D-1726 processor and 8GB of DDR4 ECC memory drive file services, virtualization and surveillance tasks. Redundant power supplies protect uptime against a single unit failure.

Suited for Centralized Storage and Virtualization

This platform fits organizations that need high-capacity SATA storage with integrated 10GbE networking and PCIe Gen 4 expansion headroom. Buyers who require more than 48GB of memory, additional drive bays beyond twelve, or faster 25GbE networking without adding expansion cards should evaluate larger chassis or higher-tier models. The operating range of 0°C to 35°C also limits deployment to standard office or data-center environments.

Dual 10GbE Ports Define Network Throughput

Two onboard RJ-45 10GbE LAN ports set the baseline bandwidth for all client access, replication and backup traffic. Synology reports sequential reads above 6,300 MB/s and writes above 3,700 MB/s under its test conditions, so the 10GbE links become the practical ceiling for large sequential workloads. Teams needing higher sustained throughput must populate the PCIe Gen 4 x8 slots with compatible network adapters.

Questions about this item

How do I verify the RS3626xs is performing correctly after initial setup?

Check the front-panel Power, HDD and LAN LEDs for normal activity, then log into the web-based management interface to confirm all twelve 12 TB drives appear healthy and the two 10GbE RJ-45 ports show link aggregation status.

What ships with the RS3626xs and what must I purchase separately?

The box contains the main 12-bay unit, accessory pack, two C13-to-C14 power cords, a front cover and all configuration items plus twelve pre-installed 12 TB enterprise drives; additional DDR4 ECC memory up to 48 GB and PCIe Gen 4 x8 expansion cards are sold separately.

Which memory capacity should I choose for the Xeon D-1726 model?

The system arrives with 8 GB of DDR4 ECC installed and supports expansion to 48 GB; select 8 GB for standard file services or add modules up to the 48 GB limit for virtualization or heavy multi-user workloads.
