Enterprise 4-bay rackmount NAS

The Synology RS1626xs+ is a 1U rackmount network-attached storage server built for business workloads. It ships fully assembled with an Intel Xeon D-1726 6-core processor, 64GB of DDR4 ECC memory, and 16TB of raw capacity across four Synology Enterprise drives. Dual 10GbE RJ-45 ports and a dedicated management LAN port are included for high-speed connectivity.

Suited for virtualization

Organizations running virtual machines, containerized apps, or heavy multi-user file sharing will benefit from the Xeon CPU and large ECC memory pool. The four drive bays limit internal expansion, so buyers who need more than four drives inside the chassis should look at larger platforms. Environments requiring faster networking than the supplied 10GbE ports will need additional adapters.

64GB DDR4 ECC memory configures the workload ceiling

The installed 64GB of DDR4 ECC RDIMM sets the practical limit for concurrent virtual machines, cache size, and database performance. This capacity is fixed in the supplied configuration and determines whether the RS1626xs+ can handle your projected memory-intensive tasks.

Questions about this item

How do I verify the Xeon D-1726 and 64GB DDR4 are running correctly after first boot?

Open DSM Control Panel, choose Info Center, and confirm the processor shows six cores and memory reads 64 GB; the built-in health dashboard will also report drive SMART status and 10GbE link speed.

What ships with the unit and which parts must be sourced separately?

The package includes the main chassis, accessory pack, two C13-to-C14 power cords, front cover, four pre-installed 4 TB enterprise drives, 64 GB DDR4 ECC RDIMM, and a Synology dual-port 10GbE PCIe card; no additional components are required for basic operation.

Which memory or drive configuration should I select for virtualization workloads?

The system arrives with 64 GB DDR4 ECC RDIMM and 16 TB of enterprise drives already installed, a combination suited for virtual machines and cache acceleration via the dual M.2 NVMe slots.
