Ready for virtualisation and file workloads
The Synology RS1626xs+ is a 1U rackmount NAS built around an Intel Xeon D-1726 processor with 16GB of DDR4 memory. It ships fully assembled with four 8TB Synology enterprise drives for 32TB of raw capacity and two 400GB NVMe cache modules. The platform targets businesses that need consolidated storage, virtualisation support and backup services in a compact form factor.
Dual 10GbE ports and managed thermals
Two RJ-45 10GbE LAN ports handle high-throughput traffic while a dedicated out-of-band management port keeps administration separate. The chassis operates between 5°C and 35°C with humidity tolerance from 8% to 80% RH, drawing power from a 100-240 VAC supply. Fan curves and airflow are tuned for continuous operation in standard server racks.
Front-access bays and expansion headroom
Four hot-swap drive bays sit behind a removable front cover for quick drive replacement without tools. Two USB 3.2 Gen 1 ports on the front provide direct attach storage or peripheral connectivity. A PCIe Gen4 x8 slot allows future addition of network cards, and the unit supports expansion to 16 drives with a compatible Synology expansion unit.

Questions about this item
How do I install the RS1626xs+ in a rack, and what step is often missed?
Mount the 1U chassis using the included accessory pack, then connect both C13 to C14 power cords for redundancy; the step often missed is wiring the out-of-band management LAN port before powering on.
Which components in the RS1626xs+ will need replacement first?
The four 8TB Synology Enterprise NAS drives and the two 400GB NVMe cache modules are the primary field-replaceable parts; the 16GB DDR4 ECC RDIMM memory can also be upgraded to 64GB later.
What thermal limit appears first when the RS1626xs+ runs sustained workloads?
The operating temperature ceiling is 35 °C; if ambient air exceeds this, the Xeon D-1726 will throttle before any other component hits its limit.
