Instant Volume Expansion & Backup
Synology DX517 provides an easy way to scale up to 5 additional hard drives
on-the-y. The RAID volume on the host Synology DiskStation can be expanded
directly without having to reformat the existing hard drives, which ensures seamless
capacity expansion without service downtime.
Synology DX517 can also be used as a dedicated local backup destination for
Synology DiskStation. When created as a separate volume, DX517 provides a great
backup solution to its local hard disks in case of system failure.
Reliable Plug-n-Use Design
Synology DX517 is connected to Synology DiskStation by an expansion cable with
custom-designed connectors on both ends. The convenient hot-swappable drive
tray design ensures simple and quick hard drive installation and recovery in the
event of failure or when additional drives are to be installed.
Green and Easy to Manage
Deep Sleep can be manually congured to take eect 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. DX517 will also power on/o automatically
along with the attached DiskStation without handling. The operation of the DX517
is entirely integrated with DSM on the host DiskStation. This design allows full
control of the whole system with your browser only.
