One thing I would look at is which datasets might run into conentions when on the same Mod27. I am not sure if this still holds true, but I would hesitate to put the JES2 Checkpoint, SPool and CA1 TMC all on the same volume. Nor would I want to put page datasets with other datasets on the same volume.
I believe you might see some poorer performace from doing this. I think there are still system datasets that need to be kept on separate volumes to prevent poor performance. However, if you are going to put on RACF Data Base on one Mod27 - nothing else on that volume, then some might question the waste of space. I am sure there is a balance to those issues.
