Enterprise 12-bay rackmount NAS
The Synology RS3626xs is a 2U rackmount network-attached storage server built for businesses that need high-capacity, centralised file storage and data protection. It ships fully assembled with twelve 24 TB enterprise drives providing 288 TB of raw capacity, plus 32 GB of DDR4 ECC memory and a 1.6 TB SSD cache for accelerated workloads. The Intel Xeon D-1726 six-core processor handles virtualization, surveillance and multi-site collaboration tasks.
288 TB raw capacity with 1.6 TB cache
Twelve 3.5-inch SATA drives deliver 288 TB of storage headroom for large file repositories, backups and media archives. The included 1.6 TB enterprise SSD cache (2 × 800 GB) absorbs frequent random reads and write bursts, keeping latency low for databases and virtual machines. When the drive bays are full, capacity can only grow by replacing drives with larger models or adding an external expansion unit.
Dual redundant supplies in 0–35 °C range
Redundant power supplies protect uptime if one unit fails, drawing 100–240 VAC at 50/60 Hz. The chassis operates between 0 °C and 35 °C with humidity from 8 % to 80 % RH, and front-panel LEDs show power, drive and network status at a glance. Fan noise scales with load but remains within typical rack-environment limits for a 2U server.

Questions about this item
Will the two 10GbE RJ-45 ports work with my existing 1GbE switch and cabling?
Yes, the 10GbE ports are backward compatible with 1GbE networks so you can connect to your current switch using standard Cat5e or Cat6 cables and still benefit from the RS3626xs processor and 32GB DDR4 memory.
How can I verify the 1.6TB Synology Enterprise cache is active after the unit is racked and powered on?
Log into DSM, open Storage Manager and confirm the two 800GB cache drives appear as a read-write cache volume; the dashboard will also show cache hit-rate statistics once workloads start running.
Does the package include drive trays and rails for the twelve 24TB drives, or must I order them separately?
The unit ships fully assembled with all twelve 24TB Synology Enterprise drives pre-installed in their trays, plus an accessory pack, two C13-C14 power cords and a front cover — no extra drive hardware is required.
