4-Bay Expansion Unit increases capacity of 1U RackStation servers


Synology RX415 delivers an effortless volume expansion and data backup solution for Synology's 1U RackStation servers by providing an additional 4 drive slots. With its new short-depth chassis design, RX415 ensures easy installation and deployment in 2-post racks and wall mount racks.







  • Plug-and-Use Design for Seamless Storage Space Upgrade
  • Online Volume Expansion
  • 12-Inch Depth to Fit in 2-Post Racks & Wall Mount Racks
  • Energy-Saving Deep Sleep Mode
  • Managed from Synology DiskStation Manager (DSM)





Volume Expansion & Backup


When drive capacity is running low on a Synology 1U RackStation, Synology RX415 provides an easy way to immediately scale capacity by providing an additional 4 slots. A RAID volume on the Synology RackStation can be expanded directly without having to reformat the existing drives, ensuring the Synology RackStation continues providing services during capacity expansion.


Synology RX415 can serve as a dedicated local backup solution for a Synology RackStation. When created as a separate volume, the Synology RX415 provides a great backup solution for local drives in case of system failure.



Reliable Plug-and-Use and Short-Depth Chassis Design


RX415 securely connects to Synology's 1U RackStation servers with a specially designed eSATA cable, ensuring easy connection and maximum data throughput. With its exceptional 12-inches short-depth chassis design, RX415 can be deployed in both industrial standard environments and smaller server rooms with limited space. Optional Synology Rail Kits are also available for easy system maintenance.



Green & Easy to Manage


Deep Sleep can be manually configured to start automatically when the system has been inactive for a period of time. This not only saves energy but also extends the lifespan of hard drives. RX415 will also smartly power on/off with the attached RackStation, so no user intervention is needed to keep this system running smartly and efficiently.
