12-bay rackmount NAS for enterprise workloads
The Synology RS3626xs is a 2U rackmount network-attached storage server built around a 6-core Intel Xeon D-1726 processor with 32GB of DDR4 ECC memory. It arrives fully assembled and tested with twelve 20TB Synology Enterprise NAS drives delivering 240TB of raw capacity plus an 800GB Synology Enterprise cache pool. This configuration targets organisations that need centralised file storage, virtualization hosting, and multi-site collaboration in a single validated platform.
Dual 10GbE and PCIe Gen 4 expansion
Two onboard 10GbE RJ-45 ports support link aggregation for bandwidth scaling and network failover without extra cards. Two PCIe Gen 4 x8 slots remain open for adding compatible 10GbE or 25GbE adapters, Fibre Channel connectivity, or additional SSD caching hardware as requirements grow. The twelve drive bays accept 3.5-inch SATA HDDs or 2.5-inch SATA SSDs, and the unit includes redundant power supplies fed by two C13 to C14 cords for service continuity.
Sustained throughput for heavy datasets
Synology reports sequential performance exceeding 6,300 MB/s read and 3,700 MB/s write under its test conditions, indicating consistent throughput for large dataset access and backup windows. The Xeon D-1726 and DDR4 ECC memory combination maintains stability during prolonged virtualization or surveillance workloads. Operating limits are 0°C to 35°C and 8% to 80% relative humidity, so the rack environment must stay within those ranges for reliable 24/7 operation.
