Synology RS3626xs Xeon D-1726 12-Bay Rackmount NAS 48GB 800GB Cache 48TB

12-Bay Rackmount NAS with Xeon D-1726

The Synology RS3626xs is a 2U rackmount network-attached storage server built around a 6-core Intel Xeon D-1726 processor. It ships fully assembled with 48GB of DDR4 ECC memory, 800GB of enterprise SSD cache, and twelve 4TB Synology Enterprise drives providing 48TB of raw capacity. This configuration targets businesses needing centralized file storage, virtualization, or backup in a single validated appliance.

Pre-deployment checklist

Verify that your rack provides a 2U slot with at least 724mm of usable depth and can support 14.5kg of equipment weight. Confirm the site operates within 0°C to 35°C ambient temperature and 8% to 80% relative humidity. Ensure two C13 power outlets are available for the redundant 100-240 VAC supplies and that your network infrastructure can terminate two 10GbE RJ-45 links plus the dedicated out-of-band management port.

Integration into the rack

The unit occupies 88mm of vertical rack space and 482mm width, leaving the two PCIe Gen 4 x8 slots accessible for future 10GbE, 25GbE, or Fibre Channel adapters. Twelve front-accessible drive bays accept 3.5-inch SATA HDDs or 2.5-inch SATA SSDs, while the pre-installed cache and memory free internal DIMM and M.2 slots for other upgrades. Dual USB 3.2 Gen 1 ports on the rear simplify local backup or peripheral attachment without consuming PCIe lanes.
