Keys depend on the vendor. They can create keys for the entire machine
or for a partition. Each has rules that you'll need to find out from
them. Some just charge more for 'whole system' while some charge a fee
for each partition. IBM's keys are for the whole machine not for the
If you host all the guest partitions on one then you get most of the
benefit of lots of disk arms even on the smaller partitions.
The smaller partitions allow you to do various maintenance bits
independently such as PTFs for example. Will need to do PTFs etc on
multiple partitions. A Trade off.
You can also have things like web servers, libraries, IFS directories,
etc. with the same names because they are on separate partitions.
Backing up each smaller partition is quicker of course but you'll need
to do several instead of one. A trade off.
Of course each partition is separate so developers can't even
accidentally trash 'the other guys' data. They can be separately secured
In larger shops we see one LPAR for Production, One for pre-production
QA validation, one for user approval testing, one that is the 'official'
development partition that contains all source, and then various testing
partitions where data gets mucked about with.

What would be the pros/cons of one large R&D i5OS partition vs several smaller i5OS hosted partitions
For 3rd party products, do each hosted partition need separate license/key codes.
This would be non-VIOS.
