Will the SAS12 work with SAS6 disk shelf?

[Nipp]

Hi team!

I am planning an update to my existing NAS, that is currently connected to NetApp DS4246. I have a dell R640 that needs an HBA for that connection. So I wonder, if it makes sense to go with SAS12 HBA? The reason is to future-proof and to have longer/better support in future ESXi.

The NetApp uses QSFP connectors and I see some options like this one: 12G External SAS Cable QSFP to SFF-8644 HD Hybrid SAS 0.5~3 Meters | eBay that seems to do what I need. Or am I wrong?

Another question: Is there a SAS12 version of JBOD shelf, that is cheap, reliable and widely used (like DS4246 for the SAS6)?

Thank you.

I am certain that a SAS3 card will work with a SAS2 shelf - otherwise something is really strange. All that matters is that you get the correct cable and you should be golden.

Yes, that converter cable will work. It will be limited to SAS 6 Gb/s speeds though that will not impact the performance of mechanical hard drives.
