Enterprise 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for enterprise workloads. It ships fully assembled with twelve 24 TB Synology Enterprise drives providing 288 TB of raw capacity. A 6-core Intel Xeon D-1726 processor and 32 GB of DDR4 ECC memory power the system. Dual redundant power supplies protect against single-supply failure.

25GbE connectivity for high-throughput environments

This unit suits organisations that need 25 GbE SFP28 links for virtualization, heavy file sharing or backup targets. The included dual-port 25GbE adapter and two onboard 10GbE RJ-45 ports give flexible uplink options. Buyers who only need 1 GbE connectivity or who cannot use SFP28 cabling should consider a lower-tier model.

288 TB raw capacity with twelve enterprise drives

The decisive specification is the 288 TB raw capacity delivered by twelve pre-installed 24 TB Synology Enterprise SATA drives. This determines whether the appliance meets your storage target without additional drive purchases.

Questions about this item

How much heat and noise does the RS3626xs produce when running 24/7 with all twelve bays populated?

The unit operates from 0°C to 35°C ambient temperature and weighs 14.5 kg with dual redundant power supplies built for continuous operation.

What network cabling or switches do I need to use the 25GbE ports on the included adapter?

The adapter provides two SFP28 ports for 25GbE connections; you must supply compatible SFP28 transceivers and fibre or direct-attach cables plus a switch that supports 25GbE.

Can I keep using my existing 3.5-inch SATA drives alongside the twelve 24TB drives already installed?

The chassis accepts twelve 3.5-inch SATA HDDs or 2.5-inch SATA SSDs; all twelve bays are filled with the included 24TB drives, so no empty bays remain for additional drives.
