12-bay rackmount NAS with Xeon D-1726

The Synology RS3626xs is a 2U rackmount network-attached storage server built for enterprise environments. It arrives fully assembled with twelve 12 TB enterprise drives, 800 GB of SSD cache, and 48 GB of DDR4 ECC memory. The Intel Xeon D-1726 processor handles virtualization, backup, and multi-user file services.

Suits teams needing high-capacity shared storage

This unit fits IT departments that want a ready-to-run appliance for centralised data, snapshot replication, or surveillance recording. Buyers who require GPU-accelerated compute, fibre-channel connectivity, or a smaller desktop form factor should evaluate other platforms.

Twelve 3.5-inch SATA drive bays define capacity

The chassis accepts exactly twelve SATA hard drives or SSDs, delivering the 144 TB raw capacity shipped in this configuration. Expansion beyond twelve bays is not supported on this model, so storage growth must be planned within the installed drives.

Questions about this item

Will the two 10GbE RJ-45 ports work with my existing 1GbE switch?

Yes, the 10GbE RJ-45 ports auto-negotiate down to 1GbE so they connect directly to your current switch without extra modules.

How can I verify the 800GB cache and 144TB drives are active after setup?

Open DSM Storage Manager; the cache volume will show 800GB from the two 400GB modules and the storage pool will report 144TB across the twelve 12TB drives.

Do I need to buy rails or extra power cords for rack mounting?

The package includes an accessory pack and two C13-to-C14 power cords; sliding rails are not included and must be purchased separately if required.
