Clustered storage Space + near-line SAS or SAS JBOD

Hello everybody,

This is probably a stupid question but I haven't found a definitive answer anywhere.

Clustered storage pools seems to be supported only with SAS disks (No SATA / USB Disks / Whatever) and this is OK for me but in which category are near-line SAS disks? Are they considered as SAS disks and are they supported for a clustered storage space?

Same question for a SAS JBOD. What happens if you have for example a "DataON DNS-1640D" JBOD which is certified for Windows 2012 storage space?

Is the SAS controller of the JBOD enough for Windows 2012 to consider it as acceptable for a clustered storage space EVEN if it is populated with SATA disks?

Must it also be populated exclusively with near-line SAS or SAS disks (Or even only SAS disks)?

Thank you for your help.
