Enterprise 4-bay NAS for virtualization workloads

The Synology RS1626xs+ is a 1U rackmount server built around an Intel Xeon D-1726 processor with 16GB of DDR4 ECC memory. It targets businesses that run virtual machines, host collaborative file services or need a consolidated backup target for mission-critical data.

Dual 10GbE ports and PCIe Gen4 expansion

Two RJ-45 10GbE LAN ports and a dedicated out-of-band management port handle high-throughput traffic and remote administration simultaneously. A PCIe Gen4 x8 slot and dual M.2 NVMe slots allow the platform to grow with additional networking, storage cache or specialised accelerator cards as requirements evolve.

Pre-populated with enterprise drives and cache

The unit ships fully assembled with four 4TB Synology enterprise drives providing 16TB of raw capacity and two 1.6TB NVMe cache modules totalling 3.2TB for read-write acceleration. This configuration eliminates initial drive sourcing and RAID setup time so the system can enter production immediately.
