Hi folks This is the third and the last part of our article series about MS SQL Server 2008 R2 clustering and untill now we completed the creation of virtual machines and Windows clustering on them.
I’ve been managing SQL Server virtualized in production environments for nearly five years now, and in that time, I’ve had to do a significant amount of reading/learning about VMware as a hypervisor so that I could properly track down performance problems and in a lot of cases, prove to vendors that the problem wasn’t virtualization. It wasn’t very long ago that nobody supported virtualization, including Microsoft, despite the fact that it generally wasn’t the cause of problems.
On my blog post Virtualizing SQL on VMware Reference List , Oscar Zamora ( Blog | Twitter ) asked the following question in a comment: As a virtualized instance has the benefit of "failing over" to another physical box, would you consider clustering a virtualized instance? The answer to this question more than I want to write up in a comment, so I decided instead to blog my response.
