12-Bay NAS with Xeon D-1531

The Synology DS3622xs+ is a 12-bay desktop NAS powered by a Xeon D-1531 6-core processor running at 2.2 GHz with a 2.7 GHz turbo. It ships with 48 GB of DDR4 ECC memory and 12 TB of SATA SSD storage across twelve 1 TB drives. The unit runs Synology DSM and targets small to medium businesses needing iSCSI targets, file storage, email or domain controller roles.

Sustained multi-user workloads

With 48 GB of ECC memory and dual 10 GbE ports supporting link aggregation, the system maintains throughput for VM and container storage, high-resolution video editing and large surveillance deployments. The Xeon D-1531 provides steady compute for concurrent services without relying on short burst frequencies. Btrfs enables advanced LUN iSCSI features for consistent data integrity under load.

Single supply, sealed chassis

The server uses a single power supply within a sealed tower chassis. Two USB 3.2 ports and two expansion ports are available for peripheral or capacity growth. Drive bays accept 2.5-inch SATA SSDs installed separately. Fan and acoustic behaviour follow the standard DSM thermal profile for a 12-bay configuration.

Questions about this item

How much heat and fan noise does the DS3622xs+ with Xeon D-1531 2.2 GHz and 12 x 1 TB SATA SSDs produce under sustained load?

The single power supply and 2.5-inch SATA SSDs keep power draw modest, so the chassis fans run at lower speeds; in a typical rack or office the unit stays quiet enough for desktop placement.

Which network cables and switch ports do I need to use the 2 x 10GbE and 2 x 1GbE RJ-45 ports on this NAS?

Cat6a or better patch cords for the 10GbE links and standard Cat5e for the 1GbE links; a managed switch with 10GBASE-T ports enables link aggregation and failover.

Can I add the DS3622xs+ to an existing Synology cluster running older DSM versions without downtime?

DSM supports rolling upgrades across mixed models; the new unit joins the cluster, replicates shared folders, and takes over services while legacy units stay online.
