Volume expansion & backup

When drive capacity is running low on a Synology RackStation, Synology RX1217RP/RX1217 offers an easy way to immediately expand storage by providing 12 additional drive slots. The RAID volume on the Synology RackStation can be expanded directly without having to reformat the existing hard drives, ensuring service continuity during the expansion process. To ensure 24/7 service uptime, Synology RX1217RP is equipped with redundant power supplies, allowing automatic failover support if one of the PSUs fail.

When created as a separate volume, Synology RX1217RP/RX1217 also serves as an additional local backup destination for Synology RackStations.

Reliable plug-and-use design

Synology RX1217RP/RX1217 securely connects to Synology RackStation servers with a high-bandwidth expansion cable, ensuring maximum data throughput and smooth operation — as if they are part of the internal drives of Synology RackStation. SATA 6Gb/s interface ensures the installed drives provide high quality, outstanding data processing performance.

Green & easy to manage

Hibernation mode 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. RX1217RP/RX1217 will also smartly power on/off with the attached RackStation, so no user intervention is needed to keep this system running smartly and efficiently.

Backed by Synology drives

Leverage high sustained performance and reliability with enterprise-grade drives with built-in data protection designed for Synology systems.

  • To have better performance, we recommend creating storage volumes physically located within the same NAS or Expansion Unit, rather than creating volumes across your NAS and Expansion Unit.
  • DSM version requirement: 6.0.1-7393 or later version
