Overview

Accommodate massive storage growth

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.1 Add volumes when and where needed without interrupting services, thanks to Synology DiskStation Manager (DSM)'s online volume expansion and powerful volume management options.

Easy setup and management

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.

Fast and stable with Synology drives

Achieve higher levels of reliability with Synology's SAS and SATA enterprise drives. Backed by hundreds of thousands of hours of rigorous testing, they ensure maximum integration and optimal performance when paired with your Synology deployment.

Built with service uptime in mind

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.
