Mixing UAT and DR in the same box

Rafae Lopez — Wed, 27 Oct 2004 13:35:02 GMT

I have a quicky one for you guys. I am struggling understanding the risks and possible controls that I could put in place in the situation of having DR and UAT environments sitting on the same box. The reason is strcitly economic.
I need some light please!
Thanks,
R.

It shall not be a problem according to my knowledge. We had it a lot in big environment.

You will have to refresh the environment before you plan for DR.
Hope it helps
Thanks'

One box could be used for the both purposes. DR has to assume that the box is blank so User Acceptance Testing must be suspended while DR testing is underway.

I really prefer separate boxes for Test and DR. The DR box is also a sandbox where new OS releases, new database and OS patches are applied without caution --- you want them to blow up here and normal test/development is not affected. DR and Sandox are a much better fit because user testing (and generally development) then has no impact upon DR testing.

Hi.

It could depend on what hardware you're thinking of using, the individual requirements of each environment, and on the impact of those environments on each other should they sit together in the same operating environment.

You could, for example, VPAR a system and use one partition for DR and the other for UAT. That way you can keep the environments separate from each other, but there is a cost involved for VPAR. Plus side is you can use it on existing hardware. We have N-Class servers running VPAR for development purposes.

If you're looking at new hardware (like an rp84xx for example), then you could nPAR the system. You don't have to worry about buying VPAR then.

Trouble is, an rp84xx isn't cheap - then again, I don't know what your 'economic reasons' are and how far you can stretch them!
