I currently have a FAS2050 with two heads running DataOnTap 18.104.22.168P4. It's connected to a DS14-AT shelf. We're at a point where we're going to need more storage, but might not have enough capital for a new controller, so I'm looking around for DS4243 shelves. I know that this is a SAS shelf that will need a new HBA on our controllers. My question is if I can run both the DS14 via SFP fiber and the DS4243 via SAS at the same time. My intention would be to eventually move everything off the DS14 entirely, given I can make the DS4243 big enough.
Also, is there a specific part number for the SAS HBA? I can't seem to find any on the Netapp website.
