Built for enterprise storage
The Synology RS3626xs is a 12-bay rackmount NAS populated with twelve 24TB enterprise drives for 288TB of raw capacity. It ships with 32GB of DDR4 memory and a 3.2TB dual-drive cache ready for demanding business workloads such as virtualization, surveillance and multi-site collaboration. The unit arrives fully assembled and tested so it can be racked and commissioned without additional integration effort. Buyers who need a smaller footprint or fewer drive bays will not match this density in a single 2U chassis.
Thermals and power in normal use
Dual redundant power supplies accept 100-240 VAC at 50 or 60 Hz and protect service continuity if one module fails. The system is rated for continuous operation between 0°C and 35°C with humidity from 8% to 80% RH. Two 10GbE RJ-45 ports and a dedicated out-of-band management port handle network traffic without adding external adapters that increase heat load. Builders who require passive cooling or operation above 35°C cannot meet those conditions with this hardware.
What the bundled kit changes
The package includes the main unit, an accessory pack, two C13-to-C14 power cords and a front cover so the rack installation is complete out of the box. Pre-installed Synology enterprise drives and cache modules eliminate drive-matching guesswork and firmware mismatch risk. Two PCIe Gen 4 x8 slots remain open for future 10GbE, 25GbE or Fibre Channel expansion as requirements evolve. Administrators who expect tool-less drive trays or hot-swap cache bays not described in the specifications will not find them here.

Questions about this item
How do I install the 2 x 1.6TB cache modules in the RS3626xs, and which step is often missed?
Insert the cache modules into the two PCIe Gen 4 x8 slots; the step often missed is enabling the SSD cache in DSM Storage Manager after the hardware is seated.
What maintenance or replacement will the 12 x 24TB Synology Enterprise drives need later?
The drives are rated for continuous operation; plan to replace any drive that SMART reports as degraded or after the manufacturer’s rated workload limit is reached.
What limit appears first on the RS3626xs under sustained 10GbE workloads?
The two 10GbE RJ-45 ports saturate at 10 Gbps each, so network throughput becomes the bottleneck before the CPU or cache.
