Currently, jobs like the following:
are duplicating the servers for running several tests.
The problem is it takes 4 times the space needed because the 4 test suites run sequentially thus don't need the datas until they begin.
The same applies to the following jobs through scripting;
This could be improved by preparing the data only before each test suite. This would divide the disk space needed by roughly 4 times in each job concerned.
Database tests for example run 2 test suites so twice the space needed.
The situation is even worse when 2 HF releases are in progress the same day.
