16-bay 3U rackmount NAS for enterprise

The Synology RS6426xs+ is a diskless 3U rackmount storage server designed for business and enterprise deployments. An Intel Xeon D-1739 eight-core processor running at 3 GHz provides compute power for demanding workloads. Sixteen gigabytes of DDR4 memory are installed from the factory.

Suits IT teams needing high-density 10GbE storage

Dual 10GbE RJ-45 ports deliver high-throughput networking for virtualisation, backup and file serving. The Mini-SAS HD backplane supports sixteen drive bays in a compact 3U form factor. A single USB 3.2 Gen 1 port is available for peripheral attachment. Organisations requiring fibre-channel connectivity or more than two 10GbE ports should evaluate other platforms.

Mini-SAS HD drive interface determines drive

The chassis uses a Mini-SAS HD interface for the drive backplane, so drive selection must match this connector type. Sixteen bays allow raw capacity to scale with the chosen drives. Confirm that your drive caddies and cables are designed for Mini-SAS HD before purchase.

Questions about this item

What type of drives and trays do I need to populate the 16 bays of this RS6426xs+?

The unit uses Mini-SAS HD backplane connections; you must supply 3.5-inch drives and the matching drive trays for this 3U chassis.

Will my existing 1 GbE switches bottleneck the dual 10GbE ports on this Xeon D-1739 system?

The two 10GbE RJ-45 ports will negotiate down to 1 GbE on older switches, so the NAS works but throughput is limited to the slower link speed.

How can I confirm the 16 GB DDR4 and 8-core Xeon D-1739 are recognised after first boot?

Open DSM Control Panel → Info Center; the System page lists 16 GB DDR4 memory and Intel Xeon D-1739 3 GHz 8-core processor.
