Enterprise 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need centralised file storage, data protection and virtualisation capacity in a single chassis. It ships fully assembled with twelve 8 TB enterprise-class SATA drives providing 96 TB of raw capacity and an Intel Xeon D-1726 processor with 8 GB of DDR4 ECC memory.

Sustained multi-user workloads

Under continuous demand the Xeon D-1726 six-core processor maintains consistent throughput for file serving, backup and surveillance tasks without the thermal throttling seen in burst-only benchmarks. Synology reports sequential rates exceeding 6,300 MB/s read and 3,700 MB/s write in its test environment, while redundant power supplies keep the system running during a single supply failure.

10GbE and PCIe Gen 4 expansion limits

Two onboard 10GBASE-T RJ-45 ports support link aggregation and failover, but total bandwidth cannot exceed the 10 Gb/s per port ceiling without add-in cards. Two PCIe Gen 4 x8 slots accept compatible 10GbE, 25GbE or Fibre Channel adapters, yet the chassis provides no additional bays beyond the twelve 3.5-inch SATA slots already populated.

Questions about this item

How loud and hot does the RS3626xs get when the Xeon D-1726 runs continuously?

The unit operates between 0 °C and 35 °C ambient temperature with humidity from 8 % to 80 % RH. Redundant power supplies help maintain uptime during sustained loads.

Which cables and network gear do I need to use the two 10GbE RJ-45 ports on this NAS?

Each 10GbE port uses standard RJ-45 Cat 6a or better cabling. A 10GbE-capable switch or direct peer link is required to achieve the reported 6 300 MB/s read and 3 700 MB/s write throughput.

Can I keep my existing 3.5-inch SATA drives and add them to the twelve 8 TB drives already installed?

The 12-bay chassis accepts any 3.5-inch SATA HDD or 2.5-inch SATA SSD. All twelve bays are populated with 8 TB Synology Enterprise drives, so expansion would require replacing drives or adding an expansion unit.
