12-Bay Rackmount NAS for Enterprise Workloads

The Synology RS3626xs is a 2U rackmount network-attached storage server built for demanding business environments. It ships fully assembled with twelve 12TB enterprise drives providing 144TB of raw capacity, a 6-core Intel Xeon D-1726 processor, and 32GB of DDR4 ECC memory. Dual integrated 10GbE RJ-45 ports and two PCIe Gen 4 x8 slots support high-throughput networking and expansion.

Suits Teams Needing High-Capacity Centralised

Organisations that require a single appliance for file services, virtualization, backup, or surveillance workloads will benefit from the redundant power supplies and out-of-band management port. Buyers who need more than twelve drive bays or require native 25GbE or Fibre Channel connectivity without adding expansion cards should evaluate larger platforms.

Twelve 3.5-Inch SATA Bays Define Maximum Drive Count

The chassis accepts exactly twelve 3.5-inch SATA HDDs or 2.5-inch SATA SSDs, fixing the internal storage ceiling at the installed 144TB unless drives are replaced with higher-capacity models. Expansion units can add further bays, but the base unit itself cannot accommodate additional internal drives beyond the twelve provided.

Questions about this item

How do I install the Synology 2-Port 10GbE Adapter in the RS3626xs, and what step is often missed?

Insert the adapter into one of the two PCIe Gen 4 x8 slots, secure the bracket, then enable the ports in DSM Control Panel — the step most people miss is creating the bond or VLAN before moving production traffic.

Which components in this 144 TB RS3626xs will need replacement first under 24/7 operation?

The twelve 12 TB Synology Enterprise NAS drives are the primary wear items; plan to swap any drive that SMART reports as degraded, and keep a spare 12 TB SATA drive on site.

What thermal limit appears first when the RS3626xs runs sustained heavy workloads?

The operating ceiling is 35 °C ambient; if intake air exceeds that, the system will throttle the Xeon D-1726 to protect itself.
