Linux can run on a mainframe
under the following three modes:
- BASIC
- A single operating system that owns the entire mainframe.
- LPAR
- A mainframe divided into logical partitions, with each partition
running its own operating system image. There can be up to 15 LPARs.
- VIRTUAL
- z/VM® supports hundreds
to thousands of guests. Each guest runs its own operating system—for
example, one guest using Linux and
another using z/OS®, all on
the same hardware.
