4-Bay Rackmount NAS for Enterprise Workloads

The Synology RS1626xs+ is a 1U rackmount network-attached storage server built for businesses running virtualization, backup and file-collaboration workloads. An Intel Xeon D-1726 six-core processor and 64GB of DDR4 ECC memory provide the compute headroom for simultaneous VMs and heavy multi-user access. Dual 10GbE RJ-45 ports and a dedicated management LAN keep throughput high without contending with admin traffic.

32TB Raw Capacity with 800GB NVMe Cache

Four pre-installed 8TB Synology Enterprise drives deliver 32TB of raw storage in a single volume or RAID array. Two 400GB NVMe SSD cache modules accelerate random read and write workloads such as databases and virtual-machine disks. The four-bay chassis limits internal expansion; adding a compatible Synology expansion unit is the only path to grow beyond the installed drives.

1U Chassis with Dual Power Cords and Front Cover

The unit measures 44mm high, 481.9mm wide and 668.5mm deep, weighing 9.5kg with drives installed. Two C13-to-C14 power cables support redundant power supplies for continuous uptime in rack environments. A removable front cover secures the drive bays while allowing tool-less access for drive replacement. Front-panel LEDs show power, drive and 10GbE link status at a glance.

Questions about this item

Will the 10GbE RJ-45 ports on the RS1626xs+ work with my existing 1GbE switch?

Yes, the dual 10GbE RJ-45 ports auto-negotiate down to 1GbE, so they connect directly to your current switch without extra adapters.

How can I verify the 800GB NVMe cache is active after powering on the unit?

Open DSM Storage Manager; the SSD Cache section will show both 400GB modules as healthy and display current read/write hit rates.

Which drives and accessories arrive pre-installed versus what I must add myself?

The chassis ships with four 8TB Synology Enterprise drives, two 400GB NVMe cache modules, 64GB DDR4 ECC RAM, two C13-C14 power cords, a front cover and the accessory pack — no extra parts are required for basic operation.
