There is no z/OS Linux. There *is* Linux for Sun hardware, but I don't
actually know too many people running Linux for Sparc.
Did you mean Unix up
And the answer to all of those is (drumroll please) ...
it depends.

Well, to take your original question:
The main reasons for running zSeries Linux are:
1) Direct application compatibility from other platforms while adding
the reliability of the zSeries hardware.
