Can the DX517 be set up as a backup unit? So that the main data is stored on a DS1821+ and a 1:1 backup is then created on the DX517? And can the DX517 be controlled separately from the main unit (e.g. DS1821+), e.g. in terms of sleep mode, fans, etc.?

Moin - Yes - ideally suited for backup, we use it for a cold backup and control the "decoupling" box via external mechanisms ...

Does the DX517 really go into Deep Sleep as described by Synology? Do they stay in Deep Sleep for longer or are they also switched on regularly, even though there is no access to the NAS?

When I used the DX517 as a backup extension, the discs went to sleep. If services are running on the NAS that constantly access the discs, this is logically not possible. I don't know whether the controllers in the unit also sleep. Switching on and off with the Synology always worked. I have never measured the power consumption, so I don't know how much it makes up.

Salut together, I own several Synology NAS - one of them is the DS413 - I now have to install an extension - according to the compatibility list, the DX513 should fit - is the DX517 (this one) also suitable (is probably the successor model)? In my opinion - due to the eSATA connection - this one should actually also fit, especially as the DSM versions are up to date. Thanks for a short info bg Rainer

According to Synology, DX17 is not officially on the compatibility list. It is best to send a short email to Synology for clarification.

Hello Digitec Community, Does anyone know if it is possible to set up a dedicated power schedule for the DX517 on the host DS? I really only want to use the 517 as a backup and therefore only start it once a week, make a programmed backup, then shut it down again automatically and leave the host DS (918+) running of course... LG And thx!

I have not noticed such a setting option in my setup (DS918+/DX517) so far.

Hello Digitec Community, I have a DS1515 with the DX513 expansion unit in use. Now one HDD is defective in the expansion unit. At least I thought so when I replaced it, the error was still there. I now strongly suspect that my DX513 is defective. Now my question, can I remove all the HDDs and install them in the DX517 without losing all the data? I am currently making a current backup just to be on the safe side.

I would definitely not do that because the DMS has a file table for the raid in the DX517 that corresponds to the previous configuration of the HDs. If you install the HDs of the expansion unit in the DX517, the DMS can no longer create the raid and the data is lost. This is a case for Synology support: https://www.synology.com/de-de/support (solve a support ticket at the bottom). The support generally answers the questions in a reasonable period of time (1-2 days).
