Enterprise 12-bay rackmount NAS
The Synology RS3626xs is a 2U rackmount storage server built around a 6-core Intel Xeon D-1726 processor. It arrives fully assembled with 48GB of DDR4 ECC memory and twelve 16TB Synology Enterprise SATA drives for 192TB of raw capacity. Integrated 10GbE RJ-45 ports and an included dual-port 25GbE SFP28 adapter provide high-throughput networking for virtualization, backup and multi-site collaboration workloads.
Upgrade from slower or smaller arrays
This unit replaces older NAS appliances limited to 1GbE uplinks, lower drive counts or non-ECC memory. The jump is worth it when workloads demand sustained sequential throughput above 6,300 MB/s read or 3,700 MB/s write, or when 25GbE connectivity is required for hypervisor clusters and intensive backup windows. Two PCIe Gen 4 x8 slots remain open for future cache or networking expansion.
Straightforward rack deployment
The chassis slides into a standard 19-inch rack using the included rails and dual C13-to-C14 power cords. Drives and memory are pre-installed and validated, so initial setup is limited to network configuration through the web-based management interface. Installers should verify rack depth clearance for the 724 mm chassis and confirm ambient temperature stays within the 0°C to 35°C operating range.

Questions about this item
What rack depth does the 724 mm deep RS3626xs require?
The chassis is 724 mm deep, so a rack with at least that depth is needed for the unit to seat fully.
How is the included 25GbE adapter installed, and what step is often missed?
Insert the adapter into a PCIe Gen 4 x8 slot, secure the bracket screw, then attach the SFP28 cables before powering on.
When will the twelve 16TB Synology Enterprise drives need replacement?
Replace any drive that SMART reports as degraded or that the DSM storage pool marks as failed.
