Built for Enterprise Storage

The Synology RS3626xs is a 12-bay rackmount NAS that arrives fully assembled with 288TB of raw capacity across twelve 24TB enterprise drives. An Intel Xeon D-1726 processor and 8GB of DDR4 ECC memory power demanding workloads such as virtualization, surveillance, and multi-site file collaboration. Redundant power supplies protect service availability from a single power-supply failure.

Network and Expansion Ready

Two integrated 10GbE RJ-45 ports support link aggregation for bandwidth scaling and network failover. A factory-installed dual-port 25GbE SFP28 adapter adds high-speed connectivity for intensive data access. Two PCIe Gen 4 x8 slots remain open for additional network adapters, Fibre Channel cards, or SSD caching hardware as requirements change. The chassis fits a standard 2U rack space and operates between 0°C and 35°C.

Pre-Configured for Immediate Deployment

The package includes the main unit, accessory pack, two C13 to C14 power cords, and a front cover. All twelve drive bays are populated and the system has been tested before shipment, so administrators can rack the unit, connect power and network links, and begin configuration through the web-based management interface without handling drive installation or initial hardware validation.

Questions about this item

How much DDR4 ECC memory can the Xeon D-1726 CPU address before the system hits its ceiling?

The installed 8 GB of DDR4 ECC memory can be expanded to 48 GB using the available DIMM slots.

What are the thermal and acoustic limits when the twelve 24 TB drives and 25GbE adapter run continuously?

The 2U chassis operates within 0 °C to 35 °C ambient; redundant power supplies and system fans keep components within spec during sustained loads.

Which drive interfaces and network ports must already exist in the rack for this assembled unit to operate?

Twelve 3.5-inch SATA bays are populated; the rack must provide two C13 power receptacles and 25GbE SFP28 or 10GbE RJ-45 switch ports for connectivity.
