Enterprise 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need centralised file storage, virtualisation and multi-site collaboration. It ships fully assembled with twelve 20 TB enterprise drives providing 240 TB of raw capacity, 32 GB of DDR4 memory and a 3.2 TB Synology Enterprise cache. A 6-core Intel Xeon D-1726 processor handles demanding business workloads.

Redundant power and 10GbE connectivity

Dual redundant power supplies protect service availability from a single power-supply failure. Two integrated 10GbE RJ-45 LAN ports support link aggregation for increased bandwidth and network failover, while a dedicated out-of-band management port simplifies remote administration. Two USB 3.2 Gen 1 ports and two PCIe Gen 4 x8 slots allow future expansion with additional network adapters or caching hardware. Twelve 3.5-inch drive bays accept SATA HDDs or SSDs.

Rack-optimised thermal envelope

The 88 mm high chassis operates between 0 °C and 35 °C with humidity from 8 % to 80 % RH, drawing 100-240 VAC at 50/60 Hz. Front-panel LEDs give immediate status for power, drive activity and 10GbE links. Web-based management with DHCP client support enables configuration without a dedicated console. The unit weighs 14.5 kg and measures 482 mm wide by 724 mm deep for standard rack mounting.
