The Extended Addressability Guide for z/OS says:

"While there is no practical limit to the virtual storage above the bar,
(IBM's name for the 2G limit set by the 2 ** 31 address pre-System Z)
practical limits exist to the real storage frames and auxiliary storage
slots that back the area."

At least from a design standpoint there doesn't appear to be any built in
limitation. The APIs all support getting all the virtual storage you
want. It's just until memory gets cheap enough we can actually test how well
this works but knowing IBM, it will work up to whatever they tell you will
work for physical storage and probably more than that.
