One could enlarge those data set if a new unit type with larger tracks would be defined. I admit I'm too busy (lazy) right now to RTFM but would appreciate any toughts on this (just curious). Why do we still keep the ~55k track size and increase only the number of cylinders? With modern DASD subsystems it shouldn't matter, right? What are the track size limits in z/OS? I guess it's 64k, but still this would be 16% more.
