What the RS3626xs Is

The Synology RS3626xs is a 2U 12-bay rackmount NAS built around a 6-core Intel Xeon D-1726 processor. It arrives with 48GB of DDR4 ECC memory, 800GB of enterprise SSD cache in a two-drive configuration, and twelve 8TB Synology Enterprise HDDs pre-installed for 96TB of raw capacity. Dual 10GbE RJ-45 ports and an out-of-band management LAN port are integrated.

Suits High-Capacity Enterprise Workloads.

This system targets organisations that need a single chassis delivering high throughput, hardware redundancy, and room for PCIe Gen 4 expansion cards. Buyers who require only a few terabytes, lack rack infrastructure, or prefer a tower form factor should evaluate smaller platforms instead.

12-Bay 3.5-Inch SATA Chassis Dictates Drive Choice

The enclosure accepts twelve 3.5-inch SATA hard drives or 2.5-inch SATA SSDs. That bay count and interface determine the maximum raw storage and the type of media you can install. Expansion units can add further bays if the workload outgrows the initial array.

Questions about this item

How much heat does the RS3626xs produce when running continuously in a 35 °C server room?

The unit is rated for 0 °C to 35 °C ambient temperature; dual 10 GbE ports and the Xeon D-1726 processor draw power within the 100-240 VAC supply range.

What network infrastructure must I already have to use the two 10 GbE RJ-45 ports?

A 10 GbE-capable switch and Cat6a or better cabling are required to utilise the integrated RJ-45 ports at full speed.

Can the twelve 8 TB SATA drives stay in place if I later add PCIe expansion cards?

Yes, all twelve 3.5-inch bays remain usable; the two PCIe Gen 4 x8 slots are separate from the drive bays.
