Enterprise rackmount NAS for business workloads

The Synology RS3626xs is a 12-bay 2U rackmount NAS built for centralized file storage, virtualization and multi-site collaboration. It ships fully assembled with twelve 24 TB enterprise drives delivering 288 TB raw capacity plus 3.2 TB of SSD cache. A 6-core Intel Xeon D-1726 processor and 8 GB DDR4 ECC memory provide the compute headroom for demanding business applications.

Redundant power and flexible expansion

Dual redundant power supplies protect service availability from a single power-supply failure. Two 10 GbE RJ-45 ports support Link Aggregation for higher throughput and network failover. Two PCIe Gen 4 x8 slots accept additional network adapters or cache hardware as requirements change. Front-access drive bays support 3.5-inch SATA HDDs and 2.5-inch SATA SSDs for straightforward maintenance.

Managed thermals within standard operating range

The chassis operates from 0 °C to 35 °C with humidity between 8 % and 80 % RH. Redundant fans and airflow design keep drive and processor temperatures stable under sustained loads. Power input accepts 100-240 VAC at 50/60 Hz for worldwide deployment without extra configuration.
