Synology offers the flexibility to start with a smaller storage capacity and expand as your business grows. The RX1217 and RX1217RP are 12-bay storage expansion units designed to provide seamless capacity expansion for select Synology RackStations. When drive capacity is running low on a Synology RackStation, Synology RX1217/RX1217RP 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 reformatting existing hard drives, ensuring service continuity during the expansion process. For 24/7 service uptime, Synology RX1217RP is equipped with redundant power supplies, allowing automatic failover support if one of the PSUs fails. When created as a separate volume, Synology RX1217/RX1217RP also serves as an additional local backup destination for Synology RackStations. The reliable plug-and-use design securely connects to Synology RackStation servers with a high-bandwidth expansion cable, ensuring maximum data throughput and smooth operation. The SATA 6Gb/s interface ensures installed drives provide high quality, outstanding data processing performance. In green mode, hibernation can be configured to start automatically when the system is inactive, saving energy and extending drive lifespan. RX1217/RX1217RP also powers on/off with the attached RackStation, requiring no user intervention.
