Powerstore 500T - Add more drives to enclosure, what is supported?

We have a Powerstore 500T which is not filled up with drives, but contains the following drive: SAMSUNG PM1733 1.92 TB MZWLJ1T9HBJR-00AC9.

1. Is this a Dell specific drive regarding firmware?  Can this drive only be purchased from Dell, or is it a generic SAMSUNG Drive?

2.  Does a compatibility matrix or an overview exist regarding supported drives for Powerstore 500T?
