Synology RS3626xs Xeon D-1726 12-Bay rackmount NAS 8GB 1.6TB cache 240TB

Enterprise 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for businesses that need high-capacity, centralized data management. It arrives fully assembled with twelve 20 TB enterprise drives providing 240 TB of raw storage, plus two 800 GB cache drives for accelerated access. A 6-core Intel Xeon D-1726 processor and 8 GB of DDR4 ECC memory handle virtualization, surveillance, and multi-site collaboration workloads.

Verify rack space and network infrastructure

Confirm your rack can accommodate a 2U unit measuring 88 mm high, 482 mm wide, and 724 mm deep with a weight of 14.5 kg. The system connects through two 10 GbE RJ-45 LAN ports and a dedicated out-of-band management port, so ensure your switch supports the required speeds and link aggregation. Two USB 3.2 Gen 1 ports are available for direct-attached peripherals or backup targets. Redundant power supplies require two C13 outlets fed from separate circuits for full resilience.

Thermals noise and power in normal use

The chassis operates within a 0 °C to 35 °C ambient temperature range and 8 % to 80 % relative humidity, drawing 100–240 VAC at 50/60 Hz through dual redundant supplies. Twelve enterprise drives and the Xeon processor generate measurable heat, so front-to-rear airflow must remain unobstructed in the rack. Fan speed scales with internal temperatures, producing audible airflow under sustained load. Power consumption will vary with drive activity and CPU utilisation, but the redundant design ensures continued operation if one supply fails.
