Synology DiskStation DS3622xs+ rackmount NAS Xeon D-1531 2.2GHz 48GB 48TB

12-bay rackmount NAS for multi-user workloads

The Synology DiskStation DS3622xs+ is a 12-bay rackmount NAS built around a Xeon D-1531 6-core CPU running at 2.2 GHz with a 2.7 GHz turbo. It ships with 48 GB of DDR4 ECC SODIMM memory and twelve 4 TB SATA 3.5-inch drives installed for high-capacity storage. The platform targets small and medium businesses running intensive, multi-user workloads such as iSCSI backup targets, file storage, email servers and domain controllers.

Capacity and headroom for virtualisation and video

The 48 TB raw array provides headroom for large virtual-machine libraries, container storage and high-bitrate video editing projects. Dual 10 GbE RJ-45 ports with link aggregation and failover keep throughput high when many clients access data simultaneously. Twelve drive bays allow future expansion without adding another chassis, though the single power supply means no redundancy if that unit fails.

Thermals, noise and power in normal use

A single power supply feeds the Xeon processor, memory and twelve spinning drives under typical multi-user loads. The rackmount form factor relies on front-to-rear airflow through the 12-bay chassis to keep component temperatures stable during sustained file serving or surveillance recording. Fan speed ramps with drive count and CPU utilisation, so noise rises when all bays are active but remains within expectations for a 1U-class rackmount server.
