I've got an older IBM x3200 M2 Server (MT: 4368) and I recently acquired a used internal IBM LTO 4 tape drive (FRU: 45E1125). The back of the tape drive requires an Internal SAS 29 pin connector (SFF-8482) .
I'm trying to purchase a PCIe SAS HBA that will allow me to utilize this internal tape drive and I'm having issues. I tried an Adaptec 1405 but the Server refused to move beyond POST with it installed. After talking with IBM support, they directed me to the "Server Proven" page which identified this 46M0907 SAS HBA as a proven working controller. However, when I received it, it had an external SFF-8088 external SAS connector and 4 internal connectors that appeared to be SATA. This seems to be different than the documentation which lists 4 x1 SFF-8087 ports.
I found pictures on the web of cables that looked like they went from a SATA style port to SFF-8482.
First, am I taking crazy pills? Is it that simple? Do I just need to adapt from a SATA connector to a SFF-8482? Is it possible their documentation is wrong? Can someone make a recommendation or shed some light on this issue?
