I think you're using an SR1625URSAS system with RAK and MINIDIMM installed right?
The backplane is hard wired to the midplane, so there is no way to connect any external storage to SROMBSASMP2. You can add an add-in SAS controller with external SAS ports, but the backplane can't be routed to the add-in card, which means you'll use SROMBSASMP2 for internal drives, and the add-in card for JBOD.
Make sure you select an add-in card from the Tested hardware list.
Yeah, sorry. We used to buy sr1550 systems for a long time and I messed up 1625 with 1550. sr1625ursas is what I was speaking of.
I just remember there were some Intel raid controllers with zero ports which used hdd attached to built-in motherboard host controller. So I thought if it might be possible this srombsasmp2 controller can use hdd attached to some host controller as well.
Thank's for reply
