If separate configs, which I can't personally find an overpowering reason for, you would need, most likely, two separate tape "libraries" each containing its own drive(s), or 2 separate big hard drives.
Actually two separate configs do not require separate tape libraries or drives, just tapes labelled with different "labelstr".
By this I don't mean to imply that two separate configs are the best solution for OP.
