We have a pair of powerful servers configured for fail-over, using windows servers built in fail-over clustering and hyper-V sharing san storage.
The configuration is slightly jagged as there is a Windows service running on one of these hardware nodes outside of the cluster. We then have 3 virtual machines (each windows 2008 r2 server) that are managed within the cluster, a web server, a sql database, and an application server.
All of our processing requirement fits comfortably in one hardware node, and I have recently had a hard time defending the hardware redundancy. So fail-over is now considered an expensive luxury, which has never been used.
I need to split apart (un-cluster) the servers, and run on a single hardware node (for now). This is a live environment.
What gotchas will I face?
What do I need to be aware of if anything?
Thanks.
