Synology RX1214 12-Bay Diskless Rackmount Expansion Unit

The Synology RX1214 is a dedicated storage expansion unit designed to extend the capacity of compatible Synology RackStation network-attached storage systems. With 12 drive bays in a 2U rackmount chassis, it allows administrators to significantly scale up available storage without replacing their existing NAS hardware. The unit connects to a supported RackStation — specifically the RS2414+ or RS2414RP+ — via an expansion cable, and the host NAS manages the additional drives as part of its overall storage pool. Drives can be added or swapped while the system is running thanks to hot-plug support, minimizing disruption in production environments.

The RX1214 ships diskless, giving administrators the flexibility to choose drives that match their performance and capacity requirements. Its primary limitation is its strict compatibility list — it is engineered for a specific generation of Synology RackStation hardware, and it cannot function as a standalone storage device. For organizations already running an RS2414+ or RS2414RP+ that are approaching their built-in storage limits, the RX1214 provides a clean, rack-efficient way to add up to 12 additional drives without migrating to a larger NAS platform.
