Synology RS3626xs 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server with twelve drive bays. It ships fully assembled and tested with twelve 20TB enterprise drives providing 240TB of raw capacity. An Intel Xeon D-1726 processor and 48GB of DDR4 memory power the platform for business workloads.

Suited for high-capacity centralised storage

This unit fits organisations that need a single appliance for large-scale file storage, backup, virtualization or surveillance. Buyers who require more than twelve drive bays or higher single-thread CPU performance for specialised compute tasks should evaluate alternative configurations.

Dual 10GbE RJ-45 ports with Link Aggregation

Two integrated 10GbE RJ-45 ports support Link Aggregation for increased throughput, load balancing and network failover. Sequential read performance exceeds 6,300 MB/s and write exceeds 3,700 MB/s under vendor test conditions. Two PCIe Gen 4 x8 slots allow future network or cache upgrades.

Questions about this item

What rack space and power connections does the RS3626xs need to operate?

The RS3626xs occupies a 2U rack space and requires two C13 to C14 power cords connected to 100-240 VAC 50/60Hz sources.

Can the twelve 20TB Synology Enterprise NAS drives be mixed with older SATA drives in the same volume?

The RS3626xs supports twelve 3.5-inch SATA HDDs or 2.5-inch SATA SSDs; mixing drive types is possible but volume performance will follow the slowest drive.

How do I confirm the 1.6TB cache and 10GbE ports are active after setup?

In DSM Storage Manager verify the two 800GB cache drives show as Read-Write cache, and in Control Panel Network check both 10GbE RJ-45 ports report link speeds of 10Gbps.
