Ulrich, I don't have a spare array to test this on, but how much do you loose in creating PAV's in terms of usable space on the shark / performance / internal memory usage in the shark...
Is 64 3390-3's such a bad thing considering the bottleneck on the control block?

I'm hoping to replace 64 3390-3s. If you do go to -27 disks, please make sure that the DASD string(s) for your new SPOOL volumes are defined with enough PAV aliases available so that you don't get I/O performance issues.

DSNTYPE=LARGE is exactly what I needed. Skip and Sam, thanks for your input, too. I'm going to give the 3390-27 a try, on at least on my largest system. I'm hoping to replace 64 3390-3s.
