The Scorpion 40 supports the following SCSI interfaces: 68-pin Ultra 2 SCSI (LVD) 68-pin SCSI Wide (single-ended) 50-pin SCSI-2(requires 68- to 60-pin adaptor) I currently have my hard drives on an adaptec 2120S with hot swap card. The cable runs from the raid adaptor to the card. The 2120s card is a 64bit pci card. Also, I use scsi 5 raid array and don't know if that would require me to install the tape drive on another scsi adaptor. So is the 2120S considered an Ultra 2 SCSI (LVD)? Do I need to go into the adaptec setup of the 2120s to setup the tape drive? I do not want to purchase another expensive scsi card if possible. The server will hold up to 7 320 scsi drives but currently I only have 4 and don't think I will add any more hotswap hard drives. I spent a lot of money for this tape drive and want the best performance! Oh, I also need a ribbon cable - no cable in the box, or do I really need a cable? The cable from the 2120s to the hot swap card is long and has extra connections! jay
