Enterprise Rackmount NAS
The Synology RS3626xs is a 12-bay 2U rackmount NAS built for organisations that need high-capacity centralised storage and virtualisation support. It ships fully assembled with twelve 24TB enterprise drives, 48GB of DDR4 ECC memory and 3.2TB of SSD cache. Redundant power supplies protect uptime from a single power-supply failure.
Capacity and Cache Headroom
The array delivers 288TB of raw capacity across twelve 3.5-inch SATA bays, while two 1.6TB enterprise SSDs provide a 3.2TB read-write cache tier for active workloads. This combination handles large file repositories, backup targets and virtual-machine datastores comfortably; it reaches its limit when sustained random I/O exceeds what the cache and drive count can absorb.
Network and Expansion Limits
Dual integrated 10GbE RJ-45 ports support link aggregation for bandwidth scaling and failover. Two PCIe Gen 4 x8 slots accept additional 10GbE, 25GbE or Fibre Channel adapters, so network throughput can grow with demand. Buyers who need more than twelve drive bays or higher base memory than 48GB will require a different platform.

Questions about this item
Will the two 10GbE RJ-45 ports on the RS3626xs work with my existing 1GbE switch?
Yes, the 10GbE RJ-45 ports auto-negotiate down to 1GbE so they connect to older switches without extra configuration.
How can I verify the 3.2TB cache and 288TB storage are active after installation?
Open DSM Storage Manager; the cache volume will show 3.2TB from the two 1.6TB SSD modules and the storage pool will report 288TB across the twelve 24TB drives.
What ships in the box and what must I supply myself?
The package includes the main unit, accessory pack, two C13-to-C14 power cords, front cover and all configuration items; you only need to provide network cables and rack rails.
