Termination for SCSI?

[tontod]

I just ordered a yamaha scsi cdrw. I'm also thinking of ordering a small scsi 10k drive for OS. I guess I have to terminate the scsi bus? How is this done? Software or hardware? Also, is a 10K drive going to be noisy and would I need active cooling? Thanks.

Yes, the last device on the scsi chain(cable) will have to be terminated. Unless you have an lvd HD, the termination will be done via a jumper on the drive.

Most of them are kinda noisy. Depends how quiet you are used too (system fans, etc.) You may or may not need active cooling depending on how well your case ventalates.

Depends ... your SCSI CDROM is most likely a 50 pin Ultra SCSI drive. The only 68 pin Ultra wide I know of is a plextor model. If you only have that unit on the bus, then you usually terminate it with a jumper setting on the unit. Now the hard drive is a diffent matter. I can't think of any 10K drive that is not LVD 68 pin. so that will be on a different bus ( I hope you have an LVD multi channel SCSI card). If it is LVD then the SCSI card you have usually comes with a LVD cable which has a Terminator attached.
So the short version :
CD ROM term on the unit

HD Term with external terminator

The cdrw is a yamaha ultra-scsi, the 16x write, 10x rewrite. The scsi card is an Adaptec 2940 UW.
