Synology RX1217 Expansion for RackStation (Diskless)

The Synology RX1217 is a 12-bay rackmount expansion unit purpose-built to extend the storage capacity of compatible Synology 2U RackStation NAS devices. In environments where data growth has outpaced existing drive bays, the RX1217 provides a clean path to scaling up without replacing your primary NAS or migrating data. Its plug-and-use design means you connect the unit, populate it with drives, and manage everything through the same Synology DiskStation Manager interface you already use — no additional software or management tools required.

One of the RX1217's key strengths is online volume expansion: you can add the unit and configure new storage volumes while your RackStation continues serving files, running applications, and performing backups without interruption. The 2U form factor houses 12 drive bays in a durable plastic and metal chassis measuring 88 mm x 482 mm x 696 mm, fitting standard server racks. Sold diskless, the unit gives administrators full flexibility to choose drives that match their capacity, performance, and budget requirements. Synology's 5-year limited warranty provides added assurance for what is typically a long-term infrastructure investment.
