Hello managers,

I apologies if this question does not belong to this list. I found these
lists very useful and helped me alot.

We going to have a high demand for tape backup (200GB per day) from
various platforms. We are considering the SCSI tape drives. I am
wondering if someone has experience dealing with high volume backups.
We would like to know:

(1) Effect of (n)number of tape drives on a SCSI controller.

(2) Is there an option to increase the buffer on tape drive to
    improve the performance.

(3) Is it possible to backup on two or more than two tape drive
    on one controller at the same time and get the same performance
    as if the tape drives were on different controllers.

(4) What is the best hardware configuration (controllers and drives) to
    get better performance. Any advice on type of tape drives or on any
    related info will be appreciated.

Thanks in advance.
I will summarize.
