Right now I have a HP ProLiant DL360p Gen8 with two SATA disks in the disk bays. These are the OS disks. I choose SATA disks to bypass the internal raid controller, so ZFS could do the raid.
I now need a 2U host, and would like to use SAS disks instead of SATA disks for the OS. Looking at pictures of opened HP hosts, I can only see one SATA cable going to the mainboard, where I was hoping to see one from each disk bay, as it then would be more likely that I can completely bypass the onboard controller.
So my question is
Can I just buy a LSI SAS 9207-8i, and connect the disk bays directly to that controller? Or do I need a specific HP host to do that?
