How does the DX513 Expansion Unit work?

Unread post by artis1sysop » Thu Dec 07, 2017 5:44 pm

How is the DX513 Expansion Unit treated when it's connected to our DS916+?

If we have 4 x 4TB drives in a DS916+ yielding 12TB of available space on Volume1 with SHR, then what would we have in Volume1 if we connect a DX513 with 3 x 4TB drives?

According to the Synology RAID calculator:

7 x 4TB = 24TB usable space with SHR


Is that how it works? Are the 4 drives in the DS916+ and the 3 drives in the DX513 seen as 7 drives total when calculating total available space?

How do I add the 3 drives in the DX513 to the Volume1 available space in DSM?

It is very straight forward - the expansion cabinet attaches via an e-sata cable and is completely transparent as far as adding drives. The one thing to be aware of with this however is not ever to remove the cabinet from the ds916+ when powered on if it has discs that expand the volume on it as it can break your array.

The disks are treated as internal disks.
