Sorry, I was mixed up, thanks for pointing it out. Previous posts striked out, as apparently wrong.
What confused me, is the sales blurb, seemed to say "It has SAS and SATA interfaces", but they meant that you could get particular drives in that range with either SAS, or SATA interfaces, NOT both.
Also, later in the data sheet, it says Interface: DUAL
But on further research (I already knew this, but forgot, so I should have realized), dual actually means there are two SAS interfaces.
But that is so that the HDDs, can be extra reliable, even if a disk controller (card) fails, as it can be connected to two.
tl;dr
SAS drives, don't seem to work with/as SATA drives, I was mixed up.
