Enterprise 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need high-capacity, centralised file storage and data protection. It arrives fully assembled with twelve 24 TB Synology Enterprise drives for 288 TB of raw capacity. A 6-core Intel Xeon D-1726 processor and 8 GB of DDR4 ECC memory provide a dependable platform for virtualization, surveillance and multi-site collaboration workloads.

Thermals noise and power draw

The unit operates within a 0 °C to 35 °C temperature range and 8 % to 80 % relative humidity. Redundant power supplies accept 100-240 VAC at 50/60 Hz and protect service availability from a single power-supply failure. Front-panel LEDs show power, drive and 10/100 LAN status for quick health checks during normal operation.

Build integration and expansion

Twelve 3.5-inch SATA drive bays support HDDs or 2.5-inch SATA SSDs, while two PCIe Gen 4 x8 slots allow the addition of compatible 10GbE or 25GbE network adapters, Fibre Channel connectivity or SSD caching hardware. Two integrated 10GbE RJ-45 ports support Link Aggregation for bandwidth scaling and failover, and an out-of-band management port simplifies remote administration.

Questions about this item

How do I install the twelve 24TB drives into the 12-bay chassis, and which step is commonly missed?

Slide each drive into its tray until the latch clicks, then insert trays until they lock; the step often missed is confirming every drive appears in DSM before creating a storage pool.

What maintenance will the pre-installed 24TB Synology Enterprise drives need later?

Monitor SMART health in DSM, replace any drive that reports reallocated sectors or excessive bad blocks, and keep firmware current via DSM updates.

What limit appears first under sustained heavy workloads on this Xeon D-1726 system?

The 8GB DDR4 ECC memory ceiling is reached first; DSM will swap to disk once active workloads exceed the installed 8GB.
