3.7. Consolidation of test systems

Requirement

[ug] To test software and applications, there are many test systems in the data center environment that are only ever used for tests. They are mostly used only for qualitative tests where systems are not stressed as with performance tests. However, switching between test environments by re- installation or restore of a shared test computer is out of question. The testers want to access their environment without waiting period or hassle over the right to access. Test systems are therefore underutilized.

Solution

[ug] Test systems are implemented by zones on a larger server. The details:

∙Sparse root zones / whole root zones, as needed.

∙File system decisions analogous to the production system.

∙Option: Resource management with processor sets for simultaneous tests.

∙Option: Automatic zone creation.

∙Option: Software installation per mount.

∙Option: Moving the zone among computers.

∙Option: Automatic quick installation of a zone.

Assessment

[ug] This use case has the following characteristics:

∙The operating division requires far fewer computers serving as test systems. Far fewer installations need to be performed.

∙Expensive systems for performance tests only need to be purchased once, and not for every application. Performance tests on the machines shared by the use of zones must, however, be coordinated (operation).

∙The operators can access the test installation at any time, qualitatively, at any rate; possibly not with full performance.
