SCSI Bus

Does anyone has an idea how to setup a SCSI bus that is accessible with 2 computers, as well what materials is needed to have this done?

Thanks in advance

You'd need some sort of controller between the 2 head-ends (I'm presuming you want to share drives or something between 2 machines?). I don't know of any controllers off hand that will just let you do it as an option, has to be something specialised in between, besides logic problems there'd be no termination otherwise. The only time I've seen this done is with sharing an external drive array, the one we use has 2 SCSI terminals and each can connect to a dif. server.

I see what you mean, so I need 2 scsi controllers on both machine? I wonder if one SCSI harddrive is enough for this, I wanted to setup a quorum on a physical disk that will be recognized by 2 computers/nodes.

I will try this, thanks for the advice

Not so much 2 controllers but one that is specially built to allow 2 different PCs access to it. Ours is a Dell Powervault Drive array, custom made to handle this kind of access (it's really like a SCSI versions of NAS). You may be able to buy specialised internal controllers to do the job but I think you are more likely to find it in dedicated drive arrays.
