Ready-to-deploy 12-bay rack NAS

The Synology RS3626xs arrives fully assembled with twelve 12 TB enterprise drives, 3.2 TB of SSD cache and 8 GB of DDR4 ECC memory. A 6-core Intel Xeon D-1726 processor handles file, virtualization and surveillance workloads in a 2U chassis. Redundant power supplies protect uptime from a single supply failure.

Dual 10 GbE ports with link aggregation

Two integrated RJ-45 10 GbE LAN ports support link aggregation for higher throughput, load balancing and network failover. An out-of-band management port keeps remote administration separate from data traffic. Two PCIe Gen 4 x8 slots remain open for future 10 GbE, 25 GbE or Fibre Channel adapters.

0 °C to 35 °C operating range

The unit runs between 0 °C and 35 °C at up to 80 % relative humidity. Dual redundant power supplies share the load from a 100–240 VAC source, reducing thermal stress on any single module. Front-panel LEDs give immediate status for power, drive activity and 10 GbE links.

Questions about this item

How do the 6300 MB/s read and 3700 MB/s write figures translate once the RS3626xs is loaded with the twelve 12 TB drives?

Synology measured those sequential speeds under its own test conditions with a comparable configuration; actual throughput in your environment will depend on workload mix, RAID level, and network path.

What does the dual 10GbE RJ-45 interface actually cap in daily use?

Each port runs at up to 10 Gbps; Link Aggregation can combine them for higher aggregate bandwidth, load balancing, and failover, but a single stream still maxes out at one port's line rate.

What physical space and power does the 2U chassis need to fit in a rack?

The unit measures 88 mm high, 482 mm wide, 724 mm deep and weighs 14.5 kg; it requires two C13 to C14 cords on a 100-240 VAC 50/60 Hz supply.
