Synology 12 Bay Expansion Unit DX1215 (Diskless)

Volume Expansion & Backup
When drive capacity is running low on a Synology DiskStation, Synology
DX1215 provides an easy way to immediately scale capacity by
providing an additional 12 drive slots. A RAID volume on the Synology
DiskStation can be expanded directly without having to reformat the
existing drives, ensuring the Synology DiskStation continues providing
services during capacity expansion.

Synology DX1215 can serve as a dedicated local backup solution for a
Synology DiskStation. When created as a separate volume, the Synology
DX1215 provides a great backup solution for local drives in case of
system failure.

Reliable Plug-and-Use Design
DX1215 securely connects to Synologys DiskStation servers with a
specially designed expansion cable, ensuring easy connection and
maximum data throughput. The expansion cable allows the drives in the
connected Synology DX1215 to operate as the internal ones of Synology
DiskStation.

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. DX1215 will
also smartly power on/off with the attached DiskStation, so no user
intervention is needed to keep this system running smartly and efficiently.
DX1215 comes with a fast detachable fan module with two 120 X 120mm
fans and screwless drive trays, making system components replacement
fast and tool-free
