12-Bay Rackmount NAS for Enterprise Workloads
The Synology RS3626xs is a 2U rackmount NAS built around a 6-core Intel Xeon D-1726 processor with 48GB of DDR4 ECC memory. It ships fully assembled with twelve 12TB Synology Enterprise drives providing 144TB of raw capacity plus 1.6TB of SSD cache. This configuration targets organisations needing centralised file storage, virtualisation support, and multi-site collaboration in a single validated appliance.
Installation Simplicity and Common Pitfalls
The unit arrives pre-populated with drives, memory, and cache modules, so physical installation is limited to rack mounting and connecting the two 10GbE RJ-45 ports, the out-of-band management port, and dual power cords. Web-based management handles initial volume creation and service configuration. The main risk is underestimating rack depth; the chassis extends 724mm, so verify cabinet clearance before delivery. Ensure the operating environment stays within 0°C to 35°C and 8% to 80% humidity to avoid thermal throttling.
Sustained Load Behaviour
Under continuous demand the RS3626xs leverages its Xeon D-1726 and 48GB DDR4 pool to maintain consistent throughput for virtualisation and multi-user file access. Synology quotes sequential figures of 6300 MB/s read and 3700 MB/s write in its test environment. Dual redundant power supplies protect uptime during a single module failure. Two PCIe Gen 4 x8 slots remain available for future 25GbE or Fibre Channel upgrades if workload growth demands higher network bandwidth.
