6-Bay Xeon NAS for Business Workloads

The Synology DiskStation DS1621xs+ is a desktop NAS built for small and medium business environments. It runs an Intel Xeon D-1527 4-core processor at 2.2 GHz with a 2.7 GHz turbo and 32 GB DDR4 ECC SODIMM memory. Six 1 TB SATA 2.5" SSDs provide 6 TB of high-speed storage. The unit includes DSM software for file, backup, surveillance and virtualisation services.

Who This Suits and Who Should Look Elsewhere

This NAS suits teams needing iSCSI targets, email or domain controller roles, VM and container storage, fast file sharing or video editing storage. The 10 GbE port with link aggregation and failover supports heavy multi-user traffic. Buyers who need more than six drive bays, dual power supplies or a rackmount form factor should look at other platforms.

Xeon D-1527 CPU Decides Fit

The Xeon D-1527 4-core CPU at 2.2 GHz sets the compute ceiling for every workload. Its turbo to 2.7 GHz helps bursty tasks, but sustained multi-threaded performance is fixed by this silicon. If your workloads demand higher core counts or newer instruction sets, this processor will be the limiting factor.

Questions about this item

Do I need to install the six 1 TB SATA 2.5" SSDs and the 32 GB DDR4 ECC SODIMM modules myself?

Yes, the chassis ships sealed and the drives and memory are packed separately, so you must install all six SSDs and the memory modules before first use.

Will the single 10 GbE RJ-45 port and two 1 GbE RJ-45 ports work with my existing gigabit switch?

The two 1 GbE ports connect directly to any gigabit switch, while the 10 GbE port will negotiate down to 1 GbE if the switch only supports that speed.

How can I verify the Xeon D-1527 CPU is running at its 2.2 GHz base clock and 2.7 GHz turbo after setup?

Open DSM Resource Monitor or the SSH command line and check the CPU frequency readout; it should show 2.2 GHz at idle and climb to 2.7 GHz under load.
