12-bay Xeon NAS for multi-user workloads

The Synology DS3622xs+ is a 12-bay desktop NAS powered by a six-core Intel Xeon D-1531 processor running at 2.2 GHz with turbo up to 2.7 GHz. It ships with 16 GB DDR4 ECC memory expandable to 48 GB across four SODIMM slots. The diskless chassis supports up to 216 TB raw capacity using 3.5" or 2.5" SATA drives.

Network limits of 10GbE and 1GbE ports

Two 10GbE RJ-45 ports and three 1GbE ports provide the only built-in network interfaces. Throughput tops out at the line rate of each port, so sustained sequential reads reach 4,719 MB/s while 4K random reads hit 260,691 IOPS. Two USB 3.2 Gen 1 ports and two Mini-SAS HD expansion ports add direct-attached and shelf connectivity without extra network bandwidth.

Single PCIe 3.0 x8 slot governs upgrade path

One PCI Express 3.0 x8 slot is the only internal expansion available for adding NICs, HBAs or accelerator cards. Buyers who need more than two 10GbE ports or additional storage controllers must fit everything into this single slot. The system cannot accept a second add-in card, limiting I/O growth to what one x8 device provides.

Questions about this item

Which memory configuration should I choose for this DS3622xs+?

It ships with 16GB DDR4 ECC installed across four SODIMM slots and can be expanded to 48GB total capacity.

What does the 4,719 MB/s sequential read figure mean once the unit is in a real machine?

That throughput is achieved with the Xeon D-1531 processor and 10GbE ports under optimal workloads such as VM storage or video editing.

What interface does the PCIe 3.0 x8 slot cap in practice?

The slot supports expansion cards at PCIe 3.0 x8 speeds for additional 10GbE, SAS or other add-in controllers.
