Needless to say... it really depends on the question that is being asked.
How do I calculate the amount of space a dataset needs?
Don't use IBM's 56664 track space number for anything but a sales thing?
The 3390 DASD under normal use, do not have 56664 bytes per track available.
Short block more efficient? Elaborate please. Space utilization and efficient
are not necessarily the same. Latency issues vary a lot depending on the exact
box being used for DASD. DS6K v DS8K. DS8K with rotating v solid-state ...
QSAM v BPAM v BSAM v etc...
General guidelines ...
John, The simple view is that with DASD, the bigger the block as a multiple of
the track size, the more data you can store on a track.
It almost like an IBG on the older tapes.
Best allocation or space calc is to use 1/2 track if possible, for QSAM, and
PDSs. For PDSEs using 32760 is fine

The BASIC CPU hardware for zServer is a collection of POWER PC processors with

Even Intel CPUs are Emulators
The use of the word "KEYS" in caps to indicate a mechanism that protected

As a stated, and you rightly corrected, It was more conjecture as I have no
insights into IBMs trade secrets.
I can only base my experience upon what we designed at Andor Systems, which was
Present day z/Arch machines are the combination of several POWER PC chips
working together. With the inclusion of LPAR as the only mode to operate the
machine, logically, the storage management is more than just the old storage
keys, there are also additional KEYS to manage the LPARs themselves
