Built for enterprise workloads

The Synology RS3626xs is a 12-bay rackmount NAS powered by a 6-core Intel Xeon D-1726 processor and 32 GB of DDR4 ECC memory. It arrives fully assembled with twelve 16 TB Synology enterprise drives providing 192 TB of raw capacity plus 3.2 TB of SSD cache. This configuration targets organisations that need centralised file storage, virtualization support or multi-site collaboration in a single 2U chassis.

Verify rack space and network infrastructure

The unit measures 88 mm high, 482 mm wide and 724 mm deep and weighs 14.5 kg, so confirm your cabinet depth and load rating before ordering. Two integrated 10GbE RJ-45 ports and a dedicated out-of-band management port require compatible switch ports and cabling. Two USB 3.2 Gen 1 ports are available for direct-attached backup or peripheral use, and dual C13 power inlets need matching PDU outlets.

Operating environment and thermal limits

Synology specifies an operating temperature range of 0 °C to 35 °C with humidity between 8 % and 80 % RH non-condensing. Redundant power supplies draw from 100-240 VAC 50/60 Hz sources and help maintain uptime if one module fails. Sequential throughput reaches 6,300 MB/s read and 3,700 MB/s write under vendor test conditions, indicating sustained drive and controller activity within the stated thermal envelope.

Questions about this item

What ships inside the box and what must I source myself?

The unit, accessory pack, two C13-to-C14 power cords, front cover and all configuration items are included; the twelve 16 TB drives, two 1.6 TB cache modules and 32 GB DDR4 are already installed.

Which drive and cache combination is already fitted in this build?

Twelve 16 TB Synology Enterprise NAS drives provide 192 TB raw capacity plus two 1.6 TB Synology Enterprise cache modules for 3.2 TB total cache.

What do the 6,300 MB/s read and 3,700 MB/s write figures mean for daily use?

Those are Synology's sequential benchmarks under test conditions; real-world throughput will depend on workload mix, RAID level and network configuration.
