I've got an interesting question regarding SCSI bus termination and newer 80 pin devices.
I have: 1 x Adaptec 2100S RAID controller 2 x 36 GB 80 pin SCSI drives & hot-plug boxes.
I have done a lot with SCSI over the years, and it was my understanding that the SCSI bus must be terminated at both ends. The controller (normally) handles one end and the other with either active or passive terminators. (on the disk or the bus)
I had some problems with the configuration and when querying Adaptec, they came back and said:
If you do have drive enclosures, note that you cannot use the Adaptec supplied cable with the card. This cable has terminating
resistor built-in and cannot be used on hard-drive enclosures. Basically, you do not want to use terminated cable under any circumstances if you have drive enclosures or back plane.
Anyone familiar with this? Are drive enclosures 'auto terminating' now?
TIA
Andy
