Your software plan needs to include the operating systems that you want to load on your server and how you want to integrate them, and the software that you want to facilitate your solution.
It is important to know which applications best fit your solution, and under which operating systems those applications run. IBM® Systems hardware allows you to run multiple operating systems on multiple partitions on the same server. This enables you to run the best applications in each class without concern for the operating systems under which they run. But, it also increases the complexity of your solution, which makes software planning important.
