Rob,

Most recently I did this on an 825 with 4 Processors, 6G (I think) memory and 50 15K rpm drives. Tape drives on the box are 3581s. Even paralleling the 3581's used about 10% of the CPUs. With four parallel *SAVFs we push the CPUS to 60+% and that's good for now. My CL is set to support up to 16 parallel saves.

In one case we even break the largest library into four parallel save pieces. The program that copies the *SAVFs to disk also authors a CLP that will restore everything and saves it at the beginning of the tape.

Larry,

There was quite a discussion on whether or not save files were any faster. And lots of people reported the opposite. The only new argument you bring the table is the parallel concept. That might be significant.

I'd like to know the system specs: Model and tape drive, that you enhanced. Too often I hear stuff that someone discovered in V1R2 on a B10 and take as gospel today.
