UNIX was intended to be efficient, not to do eight Times the amount of work of any other system. This uses 8 times the memory, 8 times the processor, and 8 times the bus (only 4 times if two channels, but you get the idea). A properly written CD burning tool would use the SCSI commands to send the data only once to all of the devices. This solution requires that you have a machine that is 8 times more powerful than you should actually need. We do not. We have an HP Netserver 5: a P100 with a built in narrow SCSI2 controller. Given the hardware, is there a way to burn 8 CDs at one time, or is there some mirroring code that is well written enough to facilitate it?
