Enterprise 4-bay rackmount NAS

The Synology RS1626xs+ is a 1U rackmount NAS built for organisations that require consolidated file storage, virtualisation hosting and backup services in a single appliance. It ships fully assembled with four enterprise-class drives and cache modules installed and tested.

Thermals noise and power draw

The unit operates from a 100-240 VAC supply at 50/60 Hz and is rated for an ambient range of 5°C to 35°C with humidity between 8% and 80% RH. Dual power cords provide redundant connectivity to the chassis.

Sustained load behaviour

An Intel Xeon D-1726 six-core processor and 64 GB of DDR4 ECC memory maintain throughput during extended virtualisation and multi-user file sessions. The 1.6 TB NVMe cache tier absorbs write bursts while dual 10GbE ports sustain high network throughput over long periods.

Questions about this item

How do I install the Synology RS1626xs+ into a rack and what step is often missed?

Mount the 1U chassis with the supplied accessory pack and front cover, connect both C13 to C14 power cords, attach the two 10GbE RJ-45 LAN ports and the out-of-band management LAN, then configure DSM via web browser.

What maintenance will the 1.6TB NVMe cache and 48TB of 12TB drives need later?

Monitor SMART health of the four 12TB drives and two 800GB NVMe cache modules in DSM; replace any drive that reports reallocated sectors or the cache modules if endurance thresholds are reached.

What limit appears first when the Xeon D-1726 runs sustained workloads in the 5°C to 35°C range?

The 64GB DDR4 memory ceiling is reached before CPU thermal throttling occurs, capping concurrent virtual machines or heavy caching tasks.
