Plug-and-play capacity expansion for Synology servers Expand your Synology rackmount SAS storage 12 bays at a time, for up to 84 additional 3.5"/2.5" SAS/SATA drives with a maximum of seven Synology RX1222sas expansion units. Add volumes when and where needed without interrupting services, thanks to Synology DiskStation Manager (DSM)’s online volume expansion and powerful volume management options. Connect the RX1222sas through the included expansion cable and start managing the additional storage in minutes with Storage Manager and other intuitive tools in Synology DSM. Online volume expansion enables you to add a new volume or expand RAID volumes without reformatting drives. RX1222sas’s hot-swappable drive trays, fans, and power supplies reduce the impact of maintenance on service availability, while the redundant power supply units keep your system online even in case one power source fails.
