I want to connect an old 12-bay DataStor InfoStation (which is an external storage cabinet) to an LSI MegaRAID SCSI 320-2E host bus adapter and now wonder what bus termination guidelines to follow.
The InfoStation has two HD68 ports but nowhere in the user manual is there any hint at the requirement of termination, nor does it say that it has a built in termination. The manual hints that the two ports represent separate channels and that it is possible to connect the InfoStation to two different hosts, each through each port. Also, the two ports are listed separately in the configuration menus where you set separate LUN Maps and SCSI IDs for each port. There are no "daisy-chain" or "auto-termination" options in the configuration menus and the back panel doesn't say anything about it.
The LSI HBA has two VHDCI ports and the manual explicitly states that there should be a proper termination both when connecting external units and internal units.
Perhaps this is a "point-to-point" setup which doesn't require explicit termination. Is it implicitly understood that the InfoStation is a "point-to-point" unit where the termination is built in to the device? If not, how am I supposed to terminate it when the two ports on the device appear to be on separate SCSI channels?
