Synology DX1211
12-Bay Expansion Unit for Increasing Capacity of the Synology DiskStation
Synology DX1211 delivers an effortless solution for volume expansion and data 
backup for Synology DiskStation DS2411+/DS3611xs. The DX1211 seamlessly 
scales up the storage capacity of the DS2411+/DS3611xs by an additional 12 
hard drives on-the-fly when connected directly to DS2411+/DS3611xs.
Volume Expansion & Backup
When running out of the hard drive capacity on DS2411+/DS3611xs, the DX1211 provides an easy 
way to immediately scale capacity by additional 12 hard drives. The RAID volume on DS2411+/
DS3611xs can be expanded directly without having to reformat the existing hard drives, ensuring 
the Synology DiskStation continues its service during the capacity expansion. When created 
as an independent volume, the DX1211 provides an easy solution for backing up the Synology 
DiskStations.
Reliable Plug-n-use Design
The Synology DX1211 securely connects to the DS2411+/DS3611xs via an Infiniband cable to 
carry 12 Gb/s SATA signal for the maximum throughput. It allows the hard drives in the connected 
Synology DX1211 to operate as they are the internal ones of DS2411+/DS3611xs, with no lag in data 
retrieval.
Green & Easy to Manage
HDD hibernation or HDD Deep Sleep mode can be configured to take effect automatically when the 
system has been inactive for a specified period of time. This not only saves energy but also extends 
the lifespan of the hard disks.
Synology DX1211 is managed by DSM, no additional software installation is required.
