Enterprise rackmount NAS for heavy workloads

The Synology RS3626xs is a 12-bay 2U rackmount server built around a 6-core Intel Xeon D-1726 processor with 8 GB of DDR4 ECC memory. It ships fully assembled with twelve 16 TB Synology Enterprise SATA drives for 192 TB of raw capacity. Redundant power supplies and an out-of-band management port support continuous operation in business environments.

Upgrade from smaller arrays or slower links

This unit replaces 4-bay or 8-bay NAS appliances when capacity, CPU threads or 10GbE throughput become bottlenecks. The jump is worth it when workloads demand sustained sequential speeds above 3,700 MB/s write or 6,300 MB/s read, or when virtualisation and multi-site collaboration require ECC memory and PCIe Gen 4 expansion headroom.

Limits of 10GbE and PCIe Gen 4 x8

Two onboard 10GBASE-T ports and two PCIe Gen 4 x8 slots cap network upgrades at 25GbE or Fibre Channel without changing chassis. Twelve 3.5-inch SATA bays restrict future density gains to larger SATA drives only. Maximum memory is 48 GB, so memory-heavy databases may outgrow the platform before the drive bays fill.

Questions about this item

What rack depth does the 88 mm high 12-bay chassis require?

The unit measures 482 mm wide and 724 mm deep, fitting a standard 19-inch rack with at least 724 mm of usable depth and 2U of vertical space.

Which PCIe slot should the included 2-port 10GbE adapter occupy for best performance?

Install the adapter in one of the two PCIe Gen 4 x8 slots; the step often missed is securing the low-profile bracket screw so the card stays seated during rack vibration.

How many DDR4 ECC modules can be added later to reach the maximum memory?

The system ships with 8 GB installed and supports up to 48 GB total, so additional DDR4 ECC modules can be added to the available DIMM slots when capacity needs grow.
