Enterprise 4-bay rackmount NAS for virtualization

The Synology RS1626xs+ is a 1U rackmount server built for businesses that need high-throughput file services, virtualization hosting and backup targets. An Intel Xeon D-1726 six-core processor and 32GB of DDR4 ECC memory drive demanding multi-user workloads. Four pre-installed 24TB enterprise drives deliver 96TB of raw capacity out of the box.

Dual 25GbE and 10GbE networking with redundant

Two SFP28 ports on the included PCIe adapter provide 25GbE connectivity while two RJ-45 ports handle 10GbE traffic, plus a dedicated 1GbE management link. The unit operates between 5°C and 35°C on 100-240 VAC input with two C13-to-C14 cords supplied. No acoustic or power-draw figures are published by the manufacturer.

96TB of Synology Enterprise drives in a 4-bay

The four included 24TB drives fill every bay, so no further internal expansion is possible without an external expansion unit. Buyers who need more internal bays or a different drive count should consider other form factors.

Questions about this item

How do I install the Synology 2-Port 25GbE Adapter in the PCIe Gen4 x8 slot, and what step is often missed?

Power down the unit, open the chassis, insert the adapter firmly into the PCIe Gen4 x8 slot until it clicks, secure the bracket screw, then power on and enable the ports in DSM — the step often missed is installing the Synology driver package before configuring IP addresses.

What maintenance will the four 24TB Synology Enterprise NAS Drives need over time?

Monitor SMART health via DSM, apply firmware updates when released, ensure the 5°C - 35 °C operating temperature and 8% to 80% RH humidity limits are maintained, and replace any drive that reports reallocated sectors or excessive bad blocks.

At what point does the Intel Xeon D-1726 6-core processor become the bottleneck during sustained heavy workloads?

The 6-core Xeon D-1726 hits its compute ceiling first when running multiple virtual machines, heavy deduplication, or real-time transcoding simultaneously, before the 32GB DDR4 ECC memory or the 25GbE network interfaces saturate.
