Synology RX1222sas Expansion Unit - Storage enclosure - 12 bays (SATA-600 / SAS) - rack-mountable - 2U
The Synology RX1222sas is a 12-bay expansion unit for Synology's rack-mount NAS/SAN systems — it isn't a standalone network storage server on its own, but plugs into a compatible Synology unit (via SAS expansion cable) to add extra raw drive capacity when a primary system's own bays are full or when planned storage growth needs headroom from day one. It supports both SATA and SAS hard drives/SSDs in 3.5-inch or 2.5-inch form factors across its 12 hot-swappable drive bays, and up to seven RX1222sas units can be daisy-chained off a single compatible host system for very large-scale storage expansion.
Built as a 2U rack-mountable chassis (19-inch wide, roughly 28.5-inch deep), it includes a 500W power supply and is designed with hot-swappable drive trays, fans, and dual redundant power supplies so a drive, fan, or power-supply failure can be serviced without taking the whole storage pool offline — important for business-critical file storage. Typical uses include growing a Synology NAS's total capacity for video surveillance archives, backup targets, media libraries, or virtualization datastores well beyond what a single chassis can hold internally. Backed by a 5-year manufacturer warranty. Box contents: the RX1222sas unit, 2 AC power cords, 2 expansion (SAS) cables, an accessory pack, and a quick installation guide.
