we're in the process of deploying a clustered SQL 2008 R2 platform running on windows 2008. I'm toying with building our test infrastructure to mimic production - being clustered as well. This comes at an expense as it's more hardware. I'm trying to weigh up if this expense will be worth reducing the risks that I'd have by not having a clustered test environment. Can anyone give me some pointers, links to white papers/BOL, or other ideas and suggestions on this?
Thanks in advance
